CrCu (Copper-Chromium) Alloy Wire is a high-performance conductor designed for demanding applications requiring a balance of high conductivity, mechanical strength, and thermal resistance. The copper-chromium (CrCu) alloy core offers excellent current-carrying performance, enhanced wear resistance, and high-temperature stability, making it ideal for applications where both electrical and mechanical properties are crucial.
The CrCu alloy is particularly valued for its improved strength and durability compared to pure copper, while maintaining good electrical conductivity. It is commonly used in applications where resistance to wear and high-strength are needed, such as in welding, aerospace, and high-frequency applications.
Maintains excellent electrical conductivity while offering superior wear and fatigue resistance.
High tensile strength, making it suitable for demanding mechanical applications.
Exceptional performance under high-temperature conditions, with good thermal stability.
Enhanced durability against wear and tear, ensuring long service life in harsh environments.
Suitable for various forms, including single wire, multi-stranded wires, and fine wire bundles.
Available in custom diameters, and can be coated for additional properties like corrosion resistance.
Used in welding electrodes where high wear resistance and electrical conductivity are essential.
Suitable for high-stress environments where mechanical strength and thermal stability are critical.
Used in high-frequency applications such as RF cables and microwave components.
Ideal for power transmission applications requiring both strength and conductivity.
Perfect for use in heavy-duty electrical connectors or contact wires where reliability and wear resistance are key.
