Beryllium Copper Canted Coil Spring / Spring Contact Finger
Typical application:High Voltage Switch Gear Industry/Spring Industry/Electrical Industry
Wonder Copper 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, Alloy 25) 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 (C17500, Alloy 10) Alloy is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels. The Class 3 Alloy is heat treatable.

Note: In the Brush name:
- "A" represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
- "H" stands for cold processing state (hard);
- "T" means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
