Brazing Aluminium Sheet

Brazing is similar to soldering but at higher temperatures.

Brazing aluminium sheet.

Cladding an aluminum silicon alloy with a brazing sheet provides an aluminum alloy that has the thin walls necessary for use in automobile heat exchangers as well as such desirable characteristics as high strength corrosion resistance and formability. Brazing requires less energy than welding and can be used to join dissimilar metals. Brazing is a quick and inexpensive alternative to welding. I needed a very big propane torch to raise the temperature of the parts enough to braze.

Brazing a simple aluminium joint is easy enough but the rest didn t quite go to plan. Use the right brazing rod material for the metal used in your project. Mix a small amount of flux with water to form a paste. A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.

Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. A third method of applying brazing filler metal is to use a paste mixture of flux and filler metal powder. We have developed and are refining a variety of products of this sort. I have used aluminum brazing to modify a v8 intake manifold and the mod has held for the best part of 20 years.

We will be pleased to work on your project. Heat treatable or core alloys composed mainly of manganese or magnesium are also used. The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Technically filler metals that melt above 840ºf 450ºc join by brazing instead of soldering.

I am going to build a tool case and thought it might be interesting to. The equipment in this project can be bought for as little as 30 dollars. Apply this paste to the areas on the metal pieces that will be joined using the brush. Brazing is also much easier then welding it s a lot like using a glue gun.

Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs.
