Beryllium copper: The Industrial Pioneer of High-Strength Conductive Materials
Beryllium Copper Alloy is an advanced alloy material formed by using copper as the base and adding 0.2% - 2.75% beryllium and trace amounts of nickel or cobalt and other elements. With its unique combination of physical properties, Beryllium copper has become a core engineering material in high-end fields such as aerospace, electronic communication, and intelligent manufacturing.
1. Core Performance Advantage of Beryllium copper
Balance of Strength and Elasticity of Beryllium copper
After solution treatment and aging, the tensile strength of Beryllium copper can reach 1400 MPa, the hardness (HRC) exceeds 40, while maintaining 15% - 25% of ductility. This makes the Beryllium copper the alloy with the best comprehensive mechanical properties among all copper alloys.
The Beryllium copper elastic modulus is as high as 128 GPa, making it suitable for manufacturing precision springs, contact components, and other parts that undergo repeated deformation.
Electrical conductivity and thermal conductivity of Beryllium copper
The conductivity of Beryllium copper reaches 22% - 60% IACS (International Annealed Copper Standard), which is close to 60% of pure copper and much higher than that of alternative materials such as stainless steel.
Thermal conductivity: 105 W/(m·K), effectively used for heat dissipation components (such as chip packaging bases).
Environmental adaptability of Beryllium copper
Beryllium copper has excellent corrosion resistance, resistant to seawater and organic solvents, with a salt spray test lifespan exceeding 5,000 hours.
The working temperature range is wide (-200℃ to +400℃), it is non-magnetic and resistant to creep, and is suitable for extreme environments.
