Chrome Zirconium Copper Round Bar CuCrZr Copper Hardness C18150 Copper Bar/Plate/Disk

Chrome zirconium copper, also known as C18150 or chrome zirconium copper alloy, is a specialized copper alloy that contains chromium (Cr) and zirconium (Zr) as alloying elements. This alloy exhibits unique properties that make it suitable for specific applications requiring high strength, conductivity, and resistance to wear and corrosion.

Here's some information about chrome zirconium copper:

Composition: Chrome zirconium copper typically consists of copper as the base metal, with chromium and zirconium added as alloying elements. The exact composition may vary depending on the specific manufacturer or supplier, but a typical composition range is approximately 0.1-1.2% chromium and 0.02-0.5% zirconium.

Strength and conductivity: Chrome zirconium copper offers a combination of high strength and excellent electrical conductivity. The addition of chromium and zirconium enhances the alloy's strength without significantly compromising its electrical conductivity, making it suitable for applications that require both mechanical strength and good electrical performance.

Wear and corrosion resistance: Chrome zirconium copper exhibits improved wear and corrosion resistance compared to pure copper. The presence of chromium and zirconium enhances the alloy's resistance to abrasion, erosion, and certain corrosive environments. This property is advantageous in applications involving sliding or rubbing contacts, such as electrical connectors, electrodes, and mold inserts.

Thermal conductivity: Copper is already known for its excellent thermal conductivity, and chrome zirconium copper retains this property to a large extent. It allows efficient heat transfer, making the alloy suitable for applications requiring both electrical and thermal conductivity, such as heat sinks and electrical components in high-power electronics.

Applications: Chrome zirconium copper finds applications in various industries, including:

Electrical and electronics: The alloy is often used in electrical connectors, switchgear components, circuit breakers, and electrical discharge machining (EDM) electrodes due to its combination of high strength, good electrical conductivity, and wear resistance.

Plastic injection molding: Chrome zirconium copper is employed in mold inserts and cores for plastic injection molding due to its excellent heat transfer properties, wear resistance, and resistance to corrosive plastic materials.

Welding and resistance welding electrodes: The alloy's high strength and resistance to wear make it suitable for welding electrodes, including spot welding and projection welding applications.

Aerospace and automotive: Chrome zirconium copper is used in certain aerospace and automotive applications that require high-strength electrical connectors, terminals, and conductive components.

Heat sinks and thermal management: The alloy's combination of thermal conductivity and mechanical strength makes it useful in heat sinks and thermal management applications, where efficient heat dissipation is crucial.

Machinability: Chrome zirconium copper can be machined using conventional techniques, although its high strength and toughness may require appropriate cutting tools and machining parameters to achieve optimal results.

It's important to note that specific properties and compositions of chrome zirconium copper may vary depending on the manufacturer or supplier. It's advisable to consult the relevant specifications and technical data provided by the specific source when using this alloy for a particular application.
