What Temperature Do You Need to Braze Copper? (1,100 to 1,500°F)

Brazing copper requires a specific temperature range to ensure a strong and reliable joint.

The optimal temperature range for brazing copper is typically between 1,100 and 1,500°F.

This temperature range is crucial for ensuring proper flow and adhesion of the filler metal to the copper surfaces being joined.

Explanation of Temperature Range

What Temperature Do You Need to Braze Copper? (1,100 to 1,500°F)

The temperature of 1,100 to 1,500°F is selected to be high enough to melt the filler metal used in brazing.

Filler metals typically have a lower melting point than the copper itself.

Copper has a high melting point of 1,083°C (1,981°F).

The filler metals used in brazing are designed to melt at temperatures lower than this to facilitate the brazing process without melting the base copper material.

Importance of Temperature Control

Maintaining the correct temperature is essential for several reasons.

1. Wetting and Flow of Filler Metal

At the correct brazing temperature, the filler metal will melt and flow smoothly into the joint.

This ensures a strong bond between the filler metal and the copper.

2. Capillary Action

The melted filler metal is drawn into the joint by capillary action, which is more effective at higher temperatures.

This action ensures that the joint is filled completely, leading to a stronger brazed connection.

3. Evaporation and Contamination

At very high temperatures, there is a risk of copper evaporation, which can contaminate the furnace and affect the quality of the brazed joint.

Therefore, the temperature should not exceed the upper limit of the recommended range.

Additional Considerations

Atmosphere Control

When brazing copper, it is often done in a "wet" hydrogen atmosphere to prevent oxidation and to aid in the removal of residual hydrocarbons.

This atmosphere helps in maintaining the cleanliness of the copper surfaces and the integrity of the brazed joint.

Post-Braze Processes

After brazing, copper components can undergo various heat treatments or plating processes due to the high melting point of copper.

These processes can be carried out without affecting the brazed joints.

In summary, the temperature range of 1,100 to 1,500°F is critical for successful brazing of copper.

This ensures proper filler metal flow, effective capillary action, and a strong, reliable joint without risking damage to the copper or contamination of the brazing environment.
