Aluminium Tooling Plate

C250 Aluminium Tooling Plate

Manufactured from 5083 aluminium alloy, C250 is a cast aluminium tooling plate product with a fine grain, homogenised structure.


The material offers excellent dimensional stability combined with high mechanical strength. C250 tooling plate is stress relieved while still able to retain 85% - 90% of its core strength when compared to rolled plate products. With excellent flatness, C250 provides enhanced corrosion resistance and retains excellent dimensional tolerances and flatness after machining. The plate product has excellent machining, welding and anodising capabilities, and both sides of the plate are foiled. This precision milled plate also benefits from extremely low residual stress. It is precision milled to a roughness Ra of 0.4 microns.

Typical Applications

Commercial applications for this engineering material include:

  • Jig making
  • Support plates
  • Fixture construction

We stock C250 in plate and sheet.
