The Wolfmet tungsten alloy production unit of M&I Materials is accredited to aerospace standard, AS9100 Rev D (BS EN 9100). In addition Wolfmet tungsten can be supplied in accordance with aerospace standards ASTM B777-15 or AMS 7725E.

AS9100 Rev D

This is the single common quality management standard for the aerospace industry. It is used and supported by the World’s leading aerospace companies and throughout their supply chains. AS9100 Rev D can be used by organisations across the aerospace sector, including design, manufacturing, maintenance and distributing companies.

AMS 7725

Issued by the SAE, AMS 7725 is an internationally recognised specification that outlines the conditions tungsten alloy must achieve to meet the industry standard. The guidelines consider four categories of tungsten alloy based on their tungsten percentage, magnetic and non-magnetic alloys, tensile strength, microstructure and condition. The standard also outlines specific conditions for the annealing process, as well as rules covering quality assurance and delivery.

ASTM B777

ASTM International’s ASTM B777 standard establishes the requirements for high-density tungsten base metal produced by consolidating metal powder mixtures. In addition to defining the chemical, physical and mechanical properties of tungsten alloy, it also looks at composition requirements for tungsten alloy grades.
