Applications of Alumina Copper Alloy RWMA Class 22 (UNS.C15725):

Cuberyllium C15725(RWMA Class 22) is primarily designed for applications requiring high electrical and thermal conductivities along with good elevated temperature strength. Cuberyllium C15725 has excellent cold working characteristics and can be drawn into fine wire or rolled into thin sheets.

•Seam welding wheels

•Welding tips

•Electrical motor and generator components

•Electrical relay systems components

•Vacuum tube components

•Microwave tube components

•X-ray tube components

•Hybrid circuit packages

•High performance leadframes

•Medical device components
