CUBERYLLIUM ®-Qbe1.9 also named Cube1.9Ti Beryllium Copper is the most commonly utilized Copper Beryllium
alloy and is notable for its highest strength and hardness compared
to commercial copper alloys. Qbe1.9 alloy contains appr.Ti
0.1~0.25% of Ti,and1.85~2.1% of Be 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. Qbe1.9also exhibits exceptional
resistance to stress relaxation at elevated temperatures.
