Mandatory emissions reduction targets for passenger cars and on-road commercial vehicles, in particular, the European Commission standards, are putting pressure on automotive designers and engineers to come up with a solution for reducing emissions and fuel consumption of combustion engines – and get that solution into production before the 2020 penalties go into effect.


Engine downsizing is a proven method for cutting emissions and fuel use, but the higher power densities of more efficient engines result in increased temperatures and pressures. In high temperature, high pressure environments, engine components made of conventional materials cannot reliably deliver the horsepower that consumers expect.

With our specialty automotive alloys and composites, you can push past the limitations of conventional materials, achieving greater engine efficiency, higher performance and long-term reliability. 


Our specialty alloys and composites have been proven to meet – and exceed – the demands for greater strength and thermal stability in some of the harshest, most demanding applications, including aerospace landing gear, heavy mining vehicles, oil and gas drilling equipment, automotive racing and more. 

The same specialty materials are ideal as drop in replacements for solving the emissions challenge for on-road passenger autos and commercial vehicles.


“I found ToughMet by visiting NASCAR shops and drag racing teams and finding out this is what they're using in their applications and race motors.”

- Charlie Lawlor, Owner, Short Block Charlie’s

For years, teams in Formula 1, Le Mans, NASCAR, MotoGP and other racing classes have improved their performance on the track simply by changing out engine components made of conventional materials with those made of alloys and composites such as Alloy 3, Alloy 10X, Alloy 25, PerforMetTM alloy, SupremEX® MMCs and ToughMet® alloys. 

Parts made of our alloys and composites are proven to keep engines on the track running at optimum efficiency longer than parts made of other materials. In fact, using our copper-based alloys for critical engine components such as valve guides, pistons, valve seat inserts and bearings significantly improved part life -- more than four times in some applications.

To reduce vehicle weight and component inertia, our aluminium alloys and metal matrix composites have been used in brake calipers, pistons, connecting rods and valve spring retainers.


Simply drop in components made of our materials to replace conventional steels, bronzes, aluminum alloys and rolling element bearings. Learn more about the following automotive alloys and composites:

Low Friction Alloys:

  • ToughMet alloys – high strength, low friction copper-nickel-tin alloys that provide outstanding results as valve guides, thrust washers, shims, piston rings, bearings and bushings. 

Thermal Management Alloys:

  • Alloy 3, Alloy 10X, and Alloy 25 – copper beryllium alloys that perform better than traditional materials when used for valve seats and guides.
  • PerforMet alloys – a copper-nickel-silicon-chromium alloy that outperforms other types of valve seat and guide materials.

Lightweight Composites and Alloys:

  • SupremEX MMC – a high strength metal matrix composite ideal for pistons, piston pins, connecting rods, brake caliper, turbocharger impellers and push rods. 
  • AMC4632 – an aluminum silicon alloy that is ideal for brake calipers, connecting rods and pistons.
