Overview
CuCrZr is a high-performance copper alloy that combines chromium and zirconium to enhance its mechanical and thermal properties. This alloy is prized for its excellent electrical conductivity, which is close to pure copper, while offering superior strength and resistance to softening at elevated temperatures. Developed for demanding industrial applications, CuCrZr is commonly used in environments where both high conductivity and mechanical durability are required. Its unique composition makes it a preferred choice in aerospace, power generation, and electronics industries.
Physical and Chemical Properties
CuCrZr exhibits a density of approximately 8.89 g/cm³ and a melting point around 1080°C. The alloy's electrical conductivity is typically 80-90% IACS (International Annealed Copper Standard), making it highly efficient for electrical applications. Its mechanical properties include tensile strengths ranging from 300 to 500 MPa, depending on the heat treatment. The addition of chromium and zirconium improves its resistance to softening and fatigue, making it suitable for high-stress environments.
Main Applications
CuCrZr is extensively used in electrical contacts and resistance welding electrodes due to its high conductivity and durability. It is also employed in heat sinks and cooling components for electronic devices. In the aerospace industry, this alloy is utilized in rocket engine components and other high-temperature applications. Its reliability under extreme conditions makes it indispensable in power generation equipment, such as turbine blades and connectors.
Safety and Storage
CuCrZr is generally non-toxic and poses minimal health risks under normal handling conditions. However, standard metalworking precautions, such as wearing gloves and eye protection, should be followed to prevent injuries from sharp edges or hot surfaces. Storage recommendations include keeping the alloy in a dry, cool environment to prevent oxidation. Avoid contact with corrosive substances, as they can degrade the material over time.
B2B Procurement Guide
When procuring CuCrZr, it is crucial to verify the alloy's composition and request material certification from the supplier. This ensures the material meets the required specifications for your application. Consider the form (e.g., rods, sheets, or wires) and the required mechanical properties when selecting the product. Prices vary based on purity and form, with typical ranges between $20 and $50 per kg. Bulk purchases may offer cost savings.
