About CUBERYLLIUM®:
Cuberyllium is a factory specialized on Bronze Alloy Products for
more than 20 years.
Cuberyllium has Casting, Die Forging, Extrusion and Heat Treatment
within our plants. The products manufactured have many critical
applications from autmotive to marine industry, from electrical
industry to aviation.
CUBERYLLIUM ®-172 also named Cube2--UNS. C17200 (CDA 172) Beryllium Copper is the most commonly utilized Copper Beryllium
alloy and is notable for its highest strength and hardness compared
to commercial copper alloys. C17200 alloy contains appr. 2% of
beryllium and achieves its ultimate tensile strength can exceed
1360Mpa, while the hardness approaches Rockwell C45. Meanwhile, the
electrical conductivity is a minimum of 22% IACS in the fully aged
condition.C17200 also exhibits exceptional resistance to stress
relaxation at elevated temperatures.
