Scope:

ASTM B221-21 test method covers aluminum and aluminum alloys. The method proceeds with the quality check, heat treatment, and testing of the chemical composition of materials. The results obtained from this method help in quality control, research, and performance evaluation of various aluminum alloys.

Procedure:

The specimen is manufactured as per the specified measurements, and limits are specified for the chemical composition of the material. The analysis is done by the agreement between the purchaser and the producer. Tensile strength is measured, and heat treatment is applied. Then, a stress-corrosion resistance test is performed, and various alloys’ cracking capabilities are tested. The method also covers the packaging and certification. 

Specimen Size:

Specimen size should be as per the requirements. In this case, the material should be thinner than 0.062 inches, and the diameter of the wire should be about 0.125 inches.

Data:

The method covers the certification, sampling, testing, and specimen inspection within the set limits. 

Conclusion:

ASTM B221-21 test method is specifically important for the quality assurance and durability check of aluminum alloys. In this regard, the top service provider is the Infinita Lab, which ensures efficient and reliable testing.
