W164 Copper Alloy Manufacturer

Precision Alloy is a leading manufacturer and global supplier of W164 Copper Alloy, a specialised copper-cobalt-beryllium (CuCoBe) alloy designed for exceptionally high hardness, thermal fatigue resistance, and moderate electrical conductivity. W164 is engineered for spot welding of high-strength steels, die-casting tools, and thermal-critical applications.

We provide W164 alloy in the form of electrodes, rods, bars, forged blocks, and fully-machined custom parts, backed by material certification and quality control per RWMA Class 3 and Class 4 standards.

What is W164 Copper Alloy?

W164 is a high-performance alloy composed primarily of copper, beryllium, and cobalt, combining the strength and wear resistance of tool steel with the conductivity of copper. This alloy offers exceptional resistance to deformation, erosion, and thermal crackingβ€”even at elevated temperaturesβ€”making it ideal for use in automated welding systems, injection molds, and critical tool inserts.
