C101 | Electrolytic copper
Available formats: Bars, Tubes, Plates, Plates and Plates.
C101 or CW004A is the designation for 99.9% pure copper used in a range of engineering applications.
C101 or CW004A is also known as HC or high conductivity copper. It has a nominal conductivity of 100% IACS (international standard for annealed copper). It also has high thermal conductivity. Therefore, this is the material of choice for use in conductors and electrical components, but not when the service environment is a reducing atmosphere.
High ductility and impact resistance also serve to make C101 | CW004A is an extremely useful material.
C101 | CW004A is also the base material from which common bronzes and bronzes are produced.
Applications
Copper C101 | CW004A is typically used in:
- General engineering
- electronics
- Bus bars
- Automotive
- Home appliances
- Cold formed components
Corrosion resistance
Corrosion resistance is good or excellent in most environments and atmospheres other than those containing ammonia ions.
Cold work
C101 / CW004A can be easily cold worked. When annealed, it can be easily folded and has excellent ductility.
It hardens relatively slowly and can be annealed in neutral or oxidizing atmospheres.
Hot work
C101 | CW004A works very easily when hot.
Heat treatment
Treatment or annealing of the solution can be accomplished by rapid cooling after heating to 370-650 ° C.
Machinability
C101 | CW004A has a machinability rating of 20 where CZ121 brass | CW614N is 100.
Weldability
C101 welding | CW004A is excellent. Brazability and butt weld are also considered good. Gas shielded arc welding is fairly classified. All other welding processes are not recommended.
