SupremEX® 255XE is a specialist aluminium-based alloy boasting impressive performance characteristics.

---

Based on 2124A aluminium, the material is reinforced with 25% silicon carbide, which results in a metal matrix composite (MMC). The mechanical alloying process results in a homogenously stable microstructure. This heat-treatable product provides high strength, increased component stiffness and high fatigue resistance. The alloy also benefits from improved hardness, low friction and wear-resistant characteristics.

Impressive Performance:

The impressive mechanical properties also result in a product with an excellent strength to weight ratio. We offer SupremEX® 255XE in billets (to AMS 4355), forgings and extrusions. Overall machinability is good when using conventional techniques.

Processing:

We use state-of-the-art processing equipment to cut your material to your specific size requirements. We undertake processing in-house and often process and dispatch material on the same day. We also stock material in metric and imperial sizes.

Suitability:

The alloy is highly suitable for applications requiring high strength and stiffness, with examples including structural and chassis components.
