Beryllium Copper Alloy Solution Annealing

For the typical alloy CuBe1.9 (1.8- 2%) the alloy is heated between 720 Degree C and 860 Degree C. At this point the contained beryllium is essentially ''dissolved'' in the copper matrix (alpha phase). By rapidly quenching to room temperature this solid solution structure is retained. The material at this stage is very soft and ductile and can be readily cold worked by drawing, forming rolling, or cold heading.
