Prestige Metals Supplies stock copper chromium zirconium (CW106C) to upgrade your engineering projects. Copper chrome zirconium is a high copper alloy with improved mechanical performance due to the presence of 0.5 – 1.2% chromium and 0.03 – 0.3% zirconium. Copper is soft and ductile on its own, but when combined with chromium and zirconium the strength and durability are enhanced while the heat resistance is maintained.

Copper chromium zirconium alloy is a unique material that is specifically engineered to meet the demands of various industries from automotive to manufacturing. The heat resistance and unrivalled strength of CW106C make it an ideal choice for demanding applications that require long-lasting performance, even under extreme conditions.

As leading chromium zirconium copper suppliers, Prestige Metals Supplies stock CW106C copper in round, hexagon and flat bar profiles as well as in sheet form. Contact our technical team to discuss which form of CUCR1ZR material is best for your engineering needs.

Key Features of Copper Chromium Zirconium (CW106C)

The main features of CW106C copper make it the preferred choice for industries that demand optimal performance and reliability. Some of the key features include: 

  • High electrical conductivity
  • Excellent thermal conductivity
  • High mechanical strength and durability 
  • Very good resistance to corrosion
  • Outstanding heat resistance

Copper Chromium Zirconium Properties

CUCR1ZR material exhibits remarkable properties that combine high strength with exceptional wear and corrosion resistance. The wear resistance and toughness make it perfectly suited for demanding applications where long-lasting performance is necessary.

Copper chrome zirconium has an exceptional ability to withstand high temperatures making it ideally suited for resistance welding applications. While the addition of chromium and zirconium gives this alloy its durability, the presence of copper makes CW106 resistant to softening up to 525 degrees Celsius.

In addition to its mechanical and thermal properties, copper chromium zirconium alloy has excellent electrical conductivity. This means that CW106C copper is excellent for applications requiring electrical current flow with minimal resistance like developing current-carrying components or electrical contacts.

The copper chromium zirconium properties include excellent resistance to corrosion making it an ideal choice for harsh chemical environments. This property increases the lifespan of components made from copper chrome zirconium and reduces the risk of degradation.
