Step 2
Preheat parts in an air furnace to prepare for dip brazing.![](https://www.thermalvac.com/wp-content/themes/thermalvac_NEW/scripts/timthumb.php?src=https://www.thermalvac.com/wp-content/uploads/2015/03/Aluminum_Dip_Brazing-31.jpg&w=644&h=400&zc=1)
Step 3
Immerse parts in molten salt bath to melt and flow braze alloy.![](https://www.thermalvac.com/wp-content/themes/thermalvac_NEW/scripts/timthumb.php?src=https://www.thermalvac.com/wp-content/uploads/2015/03/Aluminum_Dip_Brazing-41.jpg&w=644&h=400&zc=1)
Step 4
Remove from bath to quench, clean and cool parts, aging in an air furnace as needed.![](https://www.thermalvac.com/wp-content/uploads/2015/03/aluminum-dip-sm1-1.jpg)

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.
