Material Type: Beryllium Copper
Material Group: Copper Base Alloy Strip
Beryllium copper springs are high-performance precision components manufactured from beryllium copper spring material, a copper-based alloy known for its exceptional strength, conductivity, and corrosion resistance. This material is cold rolled and may be mill hardened before fabrication to achieve superior mechanical properties and long-term reliability.
Beryllium copper combines high strength with excellent electrical conductivity, making it ideal for demanding applications requiring durability, fatigue resistance, and thermal stability.
Beryllium copper springs offer an excellent balance of physical and mechanical properties:
Spring Engineers designs and manufactures custom beryllium copper springs including compression springs, extension springs, torsion springs, and more, built to meet specific engineering and performance requirements.
