Copper brazing powder (copper based brazing material powder) is a widely used welding material for metal brazing. Due to its low melting point, good flowability, and low cost, it is used in various industrial fields. The following are its main uses and application scenarios:

1. Electronics and Electrical Industry

-Electrical component connection: used for brazing copper wires, relays, and switch contacts to ensure good conductivity and mechanical strength.

-Vacuum electronic devices: Copper solder powder can form airtight joints in sealed welding of X-ray tubes, vacuum tubes, etc.

2. Refrigeration and air conditioning equipment

-Compressor pipeline welding: used for connecting copper pipes and stainless steel components, such as evaporators, condensers, etc. in refrigeration systems.

-Heat exchanger manufacturing: brazed copper tubes and aluminum fins to improve heat dissipation efficiency.

3. Automotive industry

-Heat sink manufacturing: used for brazing heat dissipation components such as car water tanks and intercoolers.

-Sensor welding: such as copper stainless steel connections for oxygen sensors and pressure sensors.

4. Tools and Hard Alloys

-Tool brazing: The connection between the hard alloy tool head and the steel substrate improves the wear resistance and strength of the tool.

-Diamond tools: used for brazing diamond abrasive particles with metal substrates to extend tool life.

5. Home appliances and kitchenware

-Cookware manufacturing: Copper stainless steel brazing of stainless steel cookware to improve thermal conductivity and structural strength.

-Audio equipment: Welding of speaker coils and metal casings.

6. Hardware and fitness equipment

-Bicycle frame: Copper brazing powder is used for connecting frame fittings.

-Fitness equipment: welding of metal parts such as dumbbells and barbells.

7. Energy and Electricity

-Solar collector: brazing of copper tubes and heat absorbing plates to improve thermal conductivity efficiency.

-Busbar connection: Welding copper bars in power equipment to ensure low resistance and high conductivity.

Key advantages

-Strong adaptability: It can be used for brazing various materials such as copper, stainless steel, carbon steel, and hard alloys.

-Environmental trend: Cadmium free and Pb free solder materials are gradually replacing traditional formulas.

-Flexible process: suitable for various welding methods such as flame brazing, furnace brazing, high-frequency brazing, etc.
