Aluminum Dip Brazing is similar to other forms of brazing. Instead of using a furnace or torch, the aluminum assembly is immersed in a bath of molten salts which uniformly bring it up to temperature, producing consistent, leak-proof, vibration-resistant joints.

Benefits of Aluminum Dip Brazing

  • It’s clean. The molten salts act as a flux, and protect the joints from oxidation. Once the residual salts are washed away you’re left with a beautiful product which requires little in the way of final cleaning or adjustments.
  • It’s cost-effective. Aluminum Dip Brazing usually requires no expensive jigs or tooling. Instead, parts are designed to be self-locating and self-fixturing.

How it works

Step 1

Assemble parts and apply braze alloy where necessary.

Step 2

Preheat parts in an air furnace to prepare for dip brazing.

Step 3

Immerse parts in molten salt bath to melt and flow braze alloy.

Step 4

Remove from bath to quench, clean and cool parts, aging in an air furnace as needed.
