Copper and copper alloys
Till today, copper and copper alloys remain the most engineered materials because of their good electrical and thermal conductivity. Copper, a corrosion resistant metal, does not react when coming in contact to other metals and possess a distinctive aesthetic appearance. Copper and its alloys can be joined by welding and brazing. It is ductile, exhibits joint penetration and wets iron well.
Brazing
A joining process where metals are linked together by using metal filers at a temperature lower than the metal’s melting point and not higher than 450 degree Celsius is called brazing. The filer metals could be silver (Ag), gold (Au), copper (Cu), cobalt (Co), aluminium (Al) or nickel (Ni).
Brazing and welding differ from each other as in the earlier there is no requirement of melting the work pieces.
Reasons of brazing
- Brazing is cost and production effective
- Minimization of substance distortion
- Dissimilar materials can be joined easily with considerable strength
- All gap sizes ranging from small to big can be filled
- No requirement of trained staffs
Different methods of brazing
There are quite a few methods to accomplish brazing tasks depending upon the heating method because heat plays an eminent role in filling up the spaces and joining different metals. The common methods are listed below.
- Torch brazing
- Furnace brazing
- Resistance brazing
- Induction brazing
- Laser brazing
- Braze welding
Advantages of brazing
Brazing has quite a few advantages than other methods of joining metals.
- It produces clean joints without the necessity of a second or closing touch.
- It reduces the distortion of the substance as there is a uniform distribution of heating.
- This is an economical way of joining complex parts.
- Brazing has proved to be advantageous as it can be coated for better protection.
Brazing alloys for copper is the most essential soldering that provides extremely strong and corrosion resistant substances.
