Brazing

Brazing is the jointing of metals using a molten filler material, which on cooling forms a joint.

The filler metal melting temperature is above 450℃, but below the melting point of the metals.


How does it work?

Brazing joints the base metals by creating a metallurgical bond between the filler metal and the base metals.

When molten, the filler metal is drawn into the joint by capillary action.

How do you supply filler metal to 100's of joint simultaneously?

Brazing sheet!

Aluminum oxide

Aluminum oxide characteristics:

Hardness significantly above 400Mpa

High resistance to chemicals


The oxide interferes with brazing

Aluminum owes many of its properties to very strong adherent oxide film on the surface.

This oxide must be removed or broken up if joining is to occur.

There are a number of possibilities of achieving this.

Factors determining CAB production success or failure

1. Good product fit-up ( gap tolerance 0.1 to 0.15mm)

2. Adequate quantity of filler metal

3. Uniformity of flux coating

4. Interaction of flux and alloying elements

5. Furnace conditions (temperature time profile, temperature uniformity, furnace atmosphere)
