CuMg0.4/2.1322 High Temperature Alloy Wire For High-Stress Applications

CuMg0.4 (2.1322) is a copper-magnesium alloy wire known for its high strength, good conductivity, and excellent corrosion resistance. With 0.4% magnesium, it offers improved mechanical properties while maintaining good electrical performance. CuMg0.4 (also known as 2.1322) is a Copper-Magnesium (Cu-Mg) alloy wire that combines the excellent electrical and thermal conductivity of copper with the strength and corrosion resistance of magnesium. It is primarily used in applications requiring high conductivity, lightweight properties, and mechanical strength.

Trade Code

Key Features:

• High tensile strength (up to 500 MPa), making it suitable for demanding mechanical applications.
• Good electrical conductivity (~50-60% IACS), balancing strength and conductivity.
• Excellent corrosion and oxidation resistance, ideal for outdoor and high-temperature applications.
• Lightweight alternative to pure copper, reducing material costs and weight.

Applications

• Overhead Electrical Conductors: Used in power transmission lines due to its balance of strength and conductivity.
