7050 aluminium alloy combines stress corrosion resistance and toughness with exceptional strength.

---

The alloy shares many similarities with 7075 aluminium, although there are subtle differences.

Characteristics:

7050 aluminium includes increased copper, magnesium and zinc levels in the alloying mix. The alloy provides slightly improved density, toughness and corrosion resistance and benefits from exceptional strength, especially in thicker sectioned material. Such outstanding performance comes at a price - the material is unweldable, machinability is fair, and formability is poor. However, the alloy boasts the highest strength of all aluminium and excellent fatigue resistance, high fracture toughness and high resistance to stress corrosion cracking.

Suitability:

7050 aluminium is ideal for applications subjected to significant stresses and heavy loads. The alloy offers higher electrical and thermal conductivity than 7075 and may be heat-treated and anodised.

Applications in Motorsport:

Typical applications for 7050 aluminium alloy include suspension components, anti-roll bars, gears and shafts.
