Cube2--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 200 ksi, 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.

CuCo1Ni1Be--CW103C (DIN 2.1285) Cobalt Nickel Beryllium Copper Alloy contains approximately 1% Cobalt, 1% Nickel and 0.5% Beryllium. After hot forging and heat treatment processes this material gains considerably hardness, electrical and thermal conductivity as well. It is possible to have different combinations of electrical conductivity and hardness by changing the heat treatment conditions;CuCo1Ni1Be also Offers good strength and hardness characteristics coupled with conductivity in the range of 45-60 percent of copper with ultimate tensile and hardness properties approaching 140 ksi and RB 100 respectively, all of its properties are quite the same as CuCo2Be-C17500 and CuNi2Be-C17510.
