2070 Aluminium Lithium

2070 is a non-silver aluminium lithium plate product developed specifically for use in the motorsport sector.

Our alloy plate product is designed for high-strength and damage-tolerant applications requiring low density, high stiffness and excellent corrosion resistance. The addition of lithium in the alloying process increases the strength and modulus of the material while lowering the density. Our aluminium lithium plates are available in thickness from 50.8mm to 165mm (2 to 6.5 inches), and we supply in the T8E57 temper.

Toughness & Fatigue:

2070-T8E57 plate has shown comparable fracture toughness and fatigue (smooth and open hole) to the 7050 T7451 plate plate product. Fatigue crack growth in L-T and T-L orientations across gauges is generally improved compared to 7050 T7451 plate product.

Corrosion Resistance:

2070-T8E57 plate has shown excellent resistance to exfoliation corrosion and stress corrosion cracking in alternate immersion (ASTM G47) and seacoast environments.

Applications:

2070 aluminium finds use in various motorsport engineering applications, including engine components and blocks, chassis components and stiffness dominated design. The alloy is also used in drivetrains and gearboxes.
