What Are the Characteristics of High-Performance Alloys?

Chromium zirconium copper rod is an alloy copper rod made by smelting, casting, and other processes using elements such as chromium, zirconium, and copper. It combines the advantages of chromium, zirconium, and copper, with excellent corrosion resistance, good conductivity, and processing performance. Common chromium zirconium copper grades include C18150, C18200, C15000, which are widely used in electrode contact materials, welding electrodes, electrode holders, electrode seats, resistance welding electrodes and equipment components, spot welding machine abrasives and fixtures, seam welding wheels, electrical discharge spark electrodes, and soldering iron tips.


The so-called chromium zirconium copper is actually a type of bronze, namely chromium bronze. Chromium zirconium copper has high hardness at high temperatures. Chromium zirconium copper can be made into rods, tubes, wires, etc. The hardness of chromium zirconium copper is >75HRB; the softening temperature of chromium zirconium copper is 550℃; the electrical conductivity of chromium zirconium copper is >75%IACS. Chromium zirconium copper is a high-performance copper alloy that can be used in various industries. Its main components are Cu/Cr/Zr, with high strength and hardness, conductivity and thermal conductivity, good wear resistance and anti-wear properties, and significantly improved hardness, strength, conductivity, and thermal conductivity after aging treatment, and it is easy to weld.

Precautions for Processing Chromium Zirconium Copper

Chromium zirconium copper is prone to oxidation after processing, so rust protection should be applied in a timely manner after processing.

Chromium zirconium copper has good machinability and can be machined with lathes, grinders, milling machines, stamping machines, and other processing equipment.

Chromium zirconium copper alloy is non-magnetic, so please ensure that the product is securely fixed before operation.
