C17200 is also known as Alloy 25 and is the most commonly utilized beryllium copper alloy and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys. Its strength and hardness is similar to that of steel. C17200 copper's ultimate tensile and Rockwell hardness properties in a peak aged condition are in the 200 ksi range and RC 45 respectively (electrical conductivity 22% IACS minimum).
