What is a double alloy barrel?

Update:09 Oct 2021

The bi-alloy material tube is made of a composite of two alloy materials. The barrel body is formed by machining and heat treatment of steel-based alloy; the inner wall alloy layer is made of nickel-based, iron-based, and cobalt-based alloys under pressure and high temperature special process conditions to combine with the barrel matrix to form a double-alloy barrel.

The material tube has excellent corrosion resistance and wear resistance. It can be used in conjunction with steel-based metal ceramic screws, double alloy screws and other screws.

Suitable for: PA, PC, PE, PVC, PTFE, PSU, PP, ABS, PFA, PAR, PPO, POM, PMMA and other glass fiber plastic molding equipment.
