Brazing Aluminium Sheet

Brazing a simple aluminium joint is easy enough but the rest didn t quite go to plan.

Brazing aluminium sheet.

I have used aluminum brazing to modify a v8 intake manifold and the mod has held for the best part of 20 years. Apply this paste to the areas on the metal pieces that will be joined using the brush. Technically filler metals that melt above 840ºf 450ºc join by brazing instead of soldering. Use a torch that produces a high intensity flame.

Brazing is also much easier then welding it s a lot like using a glue gun. Use the right brazing rod material for the metal used in your project. The equipment in this project can be bought for as little as 30 dollars. A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.

I needed a very big propane torch to raise the temperature of the parts enough to braze. 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. 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. Brazing is similar to soldering but at higher temperatures.

Mix a small amount of flux with water to form a paste. Brazed metal can also be stronger then w. We will be pleased to work on your project. I am going to build a tool case and thought it might be interesting to.

Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs. Brazing requires less energy than welding and can be used to join dissimilar metals. When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage. We have developed and are refining a variety of products of this sort.

Quick and easy brazing aluminum copper and nonferrous metals. Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. Typically an alloy made from some combination of aluminum silicon and or zinc is used for this purpose but check the label to make sure it is intended for your type of join such as aluminum aluminum or aluminum copper. Heat treatable or core alloys composed mainly of manganese or magnesium are also used.
