How do you make beryllium copper alloy?
Question
When you purchase beryllium copper alloy (C17200) it often comes in a solution-annealed condition. This type of C17200 is created by heating the solution to 1400-1475°F (760-800°C) then quickly quenching it afterward. To braze the metal, manufacturers will often rapidly heat the solution below the aforementioned temperature range again or quench it again. This won’t affect the solution-annealed condition. To temper beryllium copper alloy, it’s aged anywhere between 550-700°F (290-370°C) for two to three hours. For beryllium copper alloy components that contain nickel or cobalt, the correct aging time will likely vary. High-conductivity beryllium copper is created with a 1.9% beryllium-copper balance. It is then tempered at approximately 850-950°F (455-510°C) from one to eight hours.
If you’re in need of high-quality C17200, the team from Busby Metals has a range of beryllium copper alloy components to choose from. Their inventory includes tempers in different varieties, as well as rod, bar, wire, tube, strip, and plate forms. For more information contact them online today or call 1 (800) 552-8729
Answer ( 1 )
Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5—3% beryllium and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining properties. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium alloys present a toxic inhalation hazard during manufacture
Properties
Beryllium copper is a ductile, weldable, and machinable alloy. Like pure copper, it is resistant to non-oxidizing acids like hydrochloric acid and carbonic acid, to plastic decomposition products, to abrasive wear, and to galling. It can be heat-treated for increased strength, durability, and electrical conductivity. Beryllium copper attains the greatest strength (to 1,400 MPa (200,000 psi)) of any copper-based alloy.[1] It has good thermal conductivity (62 Btu/ft-deg.F-H) 3-5 times more than Tool steel.
