C17200 Beryllium Copper Alloys Rods
CuBe2--C17200 (CDA 172) Beryllium Copper isthe most commonly utilized Copper Beryllium alloy and is notablefor its highest strength and hardness compared to commercial copperalloys. C17200 alloy contains appr. 2% of beryllium and achievesits ultimate tensile strength can exceed 200 ksi, while thehardness approaches Rockwell C45. Meanwhile, the electricalconductivity is a minimum of 22% IACS in the fully agedcondition.C17200 also exhibits exceptional resistance to stressrelaxation at elevated temperatures.
