CuCrZr (CuCr1Zr, DIN 17666 - C15000, W .NR. 2.1293 – Class 2 (II), CuCrZr, CW106C)
CuCrZr is a high-strength, high-conductivity copper alloy composed primarily of copper (Cu), with small amounts of chromium (Cr) and zirconium (Zr) as alloying elements. This combination gives CuCrZr exceptional mechanical and thermal properties, making it suitable for demanding applications.
Specifications:
Key Characteristics:
-
High Electrical and Thermal Conductivity: The copper base provides excellent conductivity for electrical and thermal applications.
-
Enhanced Strength: The addition of chromium and zirconium significantly increases strength and hardness while maintaining good conductivity.
-
Good Wear and Corrosion Resistance: It exhibits good resistance to wear and corrosion, particularly in harsh environments.
-
Thermal Stability: CuCrZr retains its properties at elevated temperatures, making it suitable for high-temperature applications.
Applications:
-
Electrical Contacts and Connectors: Due to its excellent conductivity and wear resistance.
-
Heat Exchangers and Thermal Management: Used in systems requiring efficient heat transfer.
-
Aerospace and Defense: For high-performance components where strength and conductivity are critical.
-
Fusion and Particle Accelerators: Often used in plasma-facing components due to its ability to withstand extreme thermal and mechanical stresses.
-
Injection Molding and Resistance Welding Electrodes: Thanks to its high wear resistance and thermal stability.
Heat Treatment:
CuCrZr is typically heat-treated to enhance its properties. The standard process involves:
-
Solution Annealing: Dissolves chromium and zirconium into the copper matrix at high temperatures.
-
Quenching: Rapid cooling to retain the alloying elements in solution.
-
Aging: A controlled heat treatment at lower temperatures to precipitate chromium and zirconium phases, which increase strength and hardness.
This alloy is widely used in industries requiring a balance between conductivity and mechanical strength.
