A390 Aluminum

A specialty die-cast aluminum alloy prized for wear resistance most alloys can't match.

Example: cast A390 Aluminum

What is it?

A high-silicon aluminum alloy built for wear resistance without needing a separate liner.

Key behavior

Extreme wear resistance and hardness from its high silicon content.

Why choose it

Parts facing repeated wear or friction that would degrade a standard aluminum casting.

Applications

Internal combustion engine cylinders, brake pistons, compressor components.

Casting notes

A specialty alloy reserved specifically for wear-critical applications.
