Due to its lighter properties, aluminium has become a key material within the manufacture of auto structures and as a company, we pride ourselves on assisting automotive tier 1 & sub tier suppliers to best utilise aluminium within integral lightweight engine and suspension components.

Alloy Heat Treatment also has a strong presence within the motorsport sector; working with OEM’s such as Mercedes and McLaren. We are able to heat treat high performance peripheral parts such as cam covers engine blocks suspension parts etc.
