ASTM B398/B398M is the ASTM specification for aluminum-alloy 6201-T81 and 6201-T83 wire for electrical purposes. It defines a clear technical reference for wire made from these conductor alloys, helping buyers, manufacturers, and quality teams align on acceptable product requirements. By focusing on the alloy temper and electrical-purpose application, the standard supports more consistent material selection, procurement, and compliance review for wire used in electrical assemblies and related work.

What is ASTM B398/B398M?

ASTM B398/B398M is a material specification that focuses on aluminum-alloy 6201-T81 and 6201-T83 wire intended for electrical purposes. In practical terms, it serves as a common basis for describing the wire's alloy type, temper condition, and general requirements under an ASTM standard. This helps reduce ambiguity when sourcing or evaluating wire products and provides a shared technical document for manufacturers, purchasers, and inspectors working with electrical conductor materials.

Where is ASTM B398/B398M used?

This standard is commonly used wherever 6201 aluminum-alloy wire is specified for electrical applications, especially in procurement and product qualification workflows. It is relevant to organizations that manufacture, supply, test, or purchase electrical wire and conductor materials. ASTM B398/B398M is also useful in engineering and quality control settings where a defined specification is needed to support material comparison, acceptance decisions, and documentation for wire intended for electrical service.

Why is ASTM B398/B398M important?

ASTM B398/B398M matters because it helps establish a consistent basis for evaluating aluminum-alloy electrical wire against recognized requirements. That consistency supports compliance, reduces sourcing uncertainty, and helps teams compare products more reliably during purchasing and testing. For companies managing electrical materials, the standard can also improve quality control by giving everyone a common technical reference for the wire designation, temper, and expected specification framework.
