Properties

Copper-Beryllium CuBe 1.9 (often called UBE2 ) is the copper alloy with the highest mechanical properties ( its strength can reach 1500 Mpa after work hardening).
Its excellent mechanical properties are associated with a good electrical conductivity (approx. 25 % IACS) and thermal conductivity, its antimagnetic properties, good resistance to wear and most corrosive environments, as well as its good resistance to cryogenic temperatures, favours its use in most industrial sectors, especially :

Electro-mechanics
Connectors
Aeronautics
Mechanics
Injected plastic
