Farmer’s Copper Ltd. maintains an inventory of Beryllium Copper in round rod and strip. The small ratio of beryllium to copper creates a family of high-copper alloys with strength as high as alloy steel. The commercial grades of beryllium copper alloys contain from 0.4 to 2.0 % beryllium. The two families consists of: (1) High strength with moderate conductivity C17200 & C17300. (2) High conductivity with moderate strength C17500 & C17510. The principle characteristics of these alloys are their excellent response to precipitation hardening treatments, excellent thermal conductivity, and resistance to stress relaxation. The high strength beryllium coppers C17200 & C17300 can be purchased in the solution annealed or cold worked tempers and can be easily formed or machined. A low-temperature heat treatment (600 degrees for 2-3 hours) produces additional maximum strength and hardness.
