The Fabrication Properties of CuBe2 (C17200) Copper Alloys
Hot Working	C17200 copper alloys have good hot working capabilities.
Cold Working	C17200 copper alloys have excellent cold working properties.
Annealing	Annealing is the process of heating metal or glass and allowing it to cool slowly. This process removes internal stresses and strengthens it. C17200 copper alloys are annealed at temperatures from 774 to 802 degrees Celsius.
Other fabrication properties	Include blanking, drawing, drilling, forming and bending, tapping, and turning.
