Production Process:

Beryllium Copper Rings
Available products:
The mainly available rings are C17200 beryllium copper rings, C17500 beryllium copper ring, C17510 beryllium copper ring, CuCo1Ni1Be beryllium copper rings.
Typical application of Beryllium Copper Rings:
Electrical Industry: 
Instrument parts, connectors, heavy duty relay parts, conductors, switch parts, fuse clips.
Industrial: 
Welding equipment parts, die casting plunger tips, high flux electromagnets, thermal transfer plates.
Alloy advantage: 
Class 4 Alloy has extremely high hardness and ultimate tensile strength although the electrical conductivity is lower than the Class 3 Alloy.

Class 4 Beryllium Copper (17200) is available in heat treatable tempers. Alloys are used in a wide range of applications requiring  high strength and stiffness with good conductivity.

Typical uses include electrical/electronic connectors, current-carrying springs, precision screw machined parts, welding electrodes, bearings, plastic molds and corrosion resistant components.
Class 3 copper is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. Class 3 castings are recommended for welder components that carry current, and are under heavy load, including heavy duty offset electrode holders. Class 3 copper is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels.
