CMW® 100 Copper Alloy


Subcategory: Copper Alloy; Nonferrous Metal

Key Words: UNS C17500 or UNS C17510 (Wrought)

Material Notes:
CMW® 100 material is a heat treatable, high strength, high conductivity copper base alloy. Its properties are a combination of highest strength and hardness with relatively high electrical and thermal conductivity. CMW® 100 material has excellent properties. The properties are developed largely by heat treatment although in some wrought forms, the alloy is additionally cold worked.

The high hardness, good wear resistance and high annealing temperatures of CMW® 100 material, coupled with sufficiently high electrical conductivity, make it ideal for electrodes used in spot and seam welding high resistance materials such as stainless steel, Nichrome, Monel metal and many of the high temperature heat resisting alloys. Its heat treatment capabilities allow forming custom bent electrode designs. The excellent casting properties of CMW® 100 material makes possible exceptionally smooth, clean castings for use as flash and projection welding dies and current carrying bushings. In resistance welders, high strength, current-carrying members formerly made of low electrical conductivity aluminum bronze can be decreased in section if made of CMW® 100 material for the same electrical requirements. Much higher currents can be handled if the sections are left the same size.CMW® 100 material is ideal for current carrying springs and structural parts where high conductivity and high strengths are required.
