Hardiall® is a wrought spinodally hardened copper alloy CuNi15Sn8 (C72900) designed for high strength applications where toughness is required.
It is non-magnetic and resists mechanical wear, galling, stress relaxation, corrosion and erosion.
It is also non-sparking.
Hardiall® can be easily machined into complex components whilst being environmentally friendly being both lead and
beryllium free, Lebronze alloys can offer it in customized sizes and shapes.
Hardiall® is used within the automotive industry for high performance and reliability automotive & motorsport
components thanks to its outstanding physical and mechanical properties.
- Key applications include Racing Cars, Powertrains (valve guides, thrust washers, bearings, piston pins and rings,…), Braking and Steering Systems (Brake caliper bushings, Steering bushings)
- Compared to conventional materials, Hardiall® enhances design optimization, with reduced mechanical clearances.
- Hardiall® also enables better fuel efficiency and lower CO2 emissions
