Casting

Cast log from Northwest Aluminum Specialties is among the highest quality material produced anywhere in the world.

All material is cast with Wagstaff AirSlip™ billet casting tooling.

This casting technique produces ingot with:

• a minimal chill zone
• wrought T6 properties without hot or cold work

• very smooth surfaces
• extremely fine homogeneous grain structure (30 to 80 microns) in 2.9" to 6" diameters
• See - Direct Forge® for more information

Homogenization

• Canefo™ furnaces are used for homogenization.
• Individual customer load cycle profiles are developed and pre-programmed into a cycle controller
• Load temperatures integrating heat-up, soak, and cooling are computer controlled to assure uniform physical properties between heats.
