Extrusion Design Tips

Aerospace Alloys

2014, 2024, 7075 & 7050 require special processing and heat treating.

We have a limited capability to extrude and process these alloys. If we cannot extrude your design due to our capabilities we will be happy to give you a referral.

Critical Dimensions

Be sure to identify the 1-2 most critical dimtensions, and tolerances required.

Cosmetic Surfaces

Be sure to identify the surfaces that are cosmetically import.

Part Size

The parts we manufacture need to fit in a 3.50” circle
