Wolfmet Tungsten Alloy Proves More Is Less
Recent increases in fuel prices and forecasts for more to come have focussed aircraft owners and operators into doing all they can to minimise their use of fuel.
With a density over sixty percent greater than lead, Wolfmet tungsten alloys may be a less-than-obvious choice of material for use in airframes, yet in mid-sized aircraft design they deliver key advantages.
Wolfmet’s high density, coupled with good mechanical properties and machining characteristics, allows designers to make significant reductions in the physical size of components. For a given moment about a pivot, Wolfmet alloys therefore allow a lighter balance weight to be sited further from the pivot point. Lower aircraft weight means better fuel efficiency, increased payload availability or greater speed capability.
Due to the very high melting point of tungsten (in excess of 3000 °C), Wolfmet alloys cannot be manufactured by traditional casting methods. To overcome this, Wolfmet alloys are manufactured by powder metallurgy techniques. One of the advantages of manufacturing by powder metallurgy methods is that small batch quantities, even single pieces, can be achieved without the severe cost penalties associated with other production methods.
M&I Materials has AS 9100 accreditation, and produces Wolfmet materials in accordance with an ISO 9001:2000 approved QA system, including Aerospace Sector Certificate Scheme TS 157-1993. Wolfmet components also meet the United States military MIL-T-21014 specification.
