Aluminum ASTM B211 vs B221
When a product is consistently represented. An attitude of excellence with an objective of error-free performance shared by all employees. Achieved through dedicated and Skilled employees, mode m facilities, controlled manufacturing processes, continuing education, and a positive work environment.
Directly related to superior value and performance and is provided to customers in terms of productivity improvements, reduced operating costs, and outstanding service. For the rest of this book, quality is simply defined as: providing goods and services that meet or exceed customer requirements.
To provide goods and services that meet this definition, the executives of the organization must have a strategic plan to lead the company along this path. The plan should contain both long-term and short-term objectives.

The window for long-term objectives should be no more than four years and preferably three years. The world changes so fast that planning more than four years ahead is not practical. Markets change at almost a constant pace. Customers' requirements do the same. A long-term strategic plan should consist of four main programs. There should be: 1 a program for futuristic quality planning, 2 a program for service and product improvement, 3 a program for employee involvement and education, and 4 a program for business systems.
These programs require a mission statement so that the goals of the program are understood. As with the quality policy statement, the mission statements for these programs should be short and to the point.
This gives precise direction to steering committees implementing these programs. Mission statements for the programs I recommend are: 1. Futuristic quality planning--Develop and drive business decisions that utilize quality tools and concepts to assure the successful introduction and implementation of new products, processes, and services to our customers. Service and product improvement--Develop and implement programs to improve office and manufacturing operations, processes, and systems leading to improvements and consistency in service and products, and reductions in internal waste.
Employee involvement and education--Utilize the inherent knowledge and expertise of our employees to identify and participate in opportunities for improvement, and provide appropriate education as needed in support of these goals. Business systems--Develop and manage the business systems required to assure quality, improve operations, and support our internal and external customers. These programs require further definition to understand how they are applied to effect continuous improvement.
Futuristic quality planning applies equally well to existing processes or products because it perpetuates continuous improvement. This planning program almost always requires the use of cross-functional teams.
The core members of this team should consist of people who have the necessary authority to make decisions that support the program.
During the course of planning activities, it will often be necessary to recruit employees who have special insight or knowledge of the process being evaluated. This will assure consistency of purpose and allow easy inclusion of participants who have had experience on other quality planning teams.
A method I have applied over the years fits the needs of both service and product manufacturing.
Both activities require futuristic quality planning to assure efficiency of operations and customer satisfaction. It does not matter if we are working in a manufacturing or service environment.
It does not matter if we are looking to improve office systems or manufacturing processes. The principles are the same: 1 flow chart the process chain for the activity or product; 2 assess the current method and effectiveness of quality control; 3 do a failure mode and effects analysis of highrisk process steps; and 4 develop a control plan to assure quality.
The SPQP process is designed to improve the quality of current services and products. When new services or products are under consideration, another quality tool should be applied to achieve maximum customer satisfaction. This other tool is quality function deployment QFD.
QFD is a very structured and extensive analysis of customer requirements and needs.
The study and application of QFD warrants a book of its own and will not be covered in this manual. We can still develop a strategic plan for customer satisfaction using only the tools contained within SPQP when applied toward new services or products if the customer is permitted to participate. I feel that most readers of this book are more interested in finding methods to improve current services, processes, or products.
The study of QFD is recommended for marketing functions and design engineers. A square box should be used to describe each major process step involved in creating the service or product. Arrows should be used to show the direction each process step takes as the total process evolves. Diamonds should indicate decision points along the process chain. Either inside or adjacent to the diamond is usually a question. Process flow lines arrows from the diamond points are used to act upon the answer and lead to the next process step.
Other universal symbols are used to reduce the amount of text contained in a flow chart. One example is an inverted triangle to indicate that an evaluation or an inspection must take place at a particular process step. An example of a flow chart using these symbols is shown in Fig. This is a flow chart for heat treating a threaded bolt in a molten salt bath. This flow chart has ten process steps.
Each individual process step could be expanded to describe the actions necessary to complete its task, but generally this is not necessary unless that particular step needs to be improved upon. This process has two decision points controlled by the furnace operator. A "yes" answer by the fur- nace operator allows the process to continue, but a "no" answer requires assistance from quality control.
At best, we can only say that these alloys are representative. Is this right?
Mike , 25 April UTC series is an open category, used for compositions not covered by any of the other 7. Sigmund , 9 May UTC Move individual alloy pages to alloy series[ edit ] I suggest we create separate articles for each alloying system and move all the different alloy articles, , etc, into their respective alloy series page, e. Otherwise there would be a whole lot of duplicated text for alloys that share the same properties.
What about the other alloy designation systems non-wrought alloys, etc? Georgewilliamherbert , 9 May UTC It's possible to do the same for cast alloys, although the nomenclature is not that standardized.
Then there could be two main sections, one for cast and one for wrought alloys. If others do, then they can reinstate it. Listed is order for most to least hits. Do you know of any other references I can use instead? Simply because a search engine or two gives the most results for x, y, z aluminium alloy doesn't mean that it's the most produced alloy.
I recommend that you search for production values for aluminium alloys. I do see your point, and agree with you though.

Where can I find an authoritative reference for the top 5 aluminium alloys produced? Apparently I'm not searching in the right places because I can't find any. The problem is, if your a backyard metal caster and hobby machinist like me you don't have access to a spectroscopy machine to determine the alloy type.
This makes knowing the production statistics and the properties and applications of the top alloys the next best thing for identifying scrap aluminium to melt. The first X can be a 1,2,3, or 4 and designate how the material was processed to the desired property limit.
The second X designates the strength level, with 8 designating full hard, 4 being half hard, and 2 being quarter hard. In other words, the property level desired is obtained by working the metal. There are other tempers, including T solution heat treated, with an array of XXX in its own right , O full annealed , W solution heat treated in process , and F in process.
This designation system is also used Magnesium Alloys. Plenty of flashlight companies and others claim their product is made from aircraft aluminium, so i came to see what the general consensus as to what it is. First, in the opening paragraph it says "Aluminium alloys can be improperly heat treated.
This causes internal element separation, and the metal then corrodes from the inside out. Aircraft mechanics deal daily with aluminium alloy corrosion. The second point of interest for me is about flashlight metal, as mentioned by the first poster in this section, and it relates to my first curiosity too In Nitecore's catalog there is a new flashlight design described as die cast, but twice as strong as their standard machined metal.
I always thought that cast almuninium was weaker than wrought aluminium presumably that includes cold rolled machinable stock , so this is interesting.
Firstly, if it's true, how so? Secondly, does the method run the risk of the type of internal corrosion that may result from the heating required to cast it? If this really works it's an excellent system for avoiding waste energy and material, and for gaining strength, and Nitecore seem to claim this as a new method, while I suspect that if this were possible, it might have been known widely for a long time by now.
Increased strength may be true of some properties, but not necessarily characteristics that are important for a flashlight. If you have the time, perhaps you could email the company and ask for a link to a paper on this.
That information is of interest to me as well and I added a comment requesting expansion. BTW: It is usually best to add something like this to the bottom of the page as most are going to look under a 7 y. Cheers Jim talk , 11 June UTC Corrosion Protection[ edit ] Can somebody add info about protecting from corrosion powder coating etc , it would be appreciated. I'd like to be able to identify alloys so I can check scrap pieces of Aluminum in my garage for suitability for casting, anodizing, welding processes, etc.
Can anybody out there share any tips such as an acid test for the presence of copper? Wizard talk , 30 May UTC Scandium in aluminum alloys[ edit ] The Scandium article mentions that there are positive benefits of alloying Scandium with Aluminum; e.
There seems to be no mention of Scandium in this article on Aluminum alloys. Any ideas why?
Is the info in the Scandium article incorrect?What about the other alloy designation systems non-wrought alloys, etc? At best, we can only say that these alloys are representative. The policy's length is not as important as its contents. F The aluminum content shall be calculated by subtracting from There are other tempers, including T solution heat treated, with an array of XXX in its own right , O full annealed , W solution heat treated in process , and F in process. N2e talk , 31 July UTC In the absence of any subject-matter experts on Aluminum alloys coming forward, I have made an initial attempt to improve the Aluminum Alloy article with the addition of a section of very well-cited text on Al-Sc alloys from the Scandium article.
NOTE 3It is standard practice in the United States aluminum industry to determine conformance to the chemical composition limits prior to further processing of ingots into wrought products. For "parts are positioned to assure even heat transfer," a 4 was chosen on severity because failure to satisfy this requirement could result in nonconformance to metallurgical properties.
A three-tiered system should be developed that includes: 1 day-to-day recognition, 2 informal recognition, and 3 formal recognition programs.
