Brazing Aluminium Sheet

Brazing requires less energy than welding and can be used to join dissimilar metals.

Brazing aluminium sheet.

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. The equipment in this project can be bought for as little as 30 dollars. Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs.

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. I am going to build a tool case and thought it might be interesting to. Quick and easy brazing aluminum copper and nonferrous metals. Use the right brazing rod material for the metal used in your project.

To learn more about hi temp brazing s aluminium brazing aluminium dip brazing and dip brazing services contact us directly to discuss how dip brazing can provide you with a better and more flexible alternative to more traditional forms of metal fusion. Brazing is a quick and inexpensive alternative to welding. Apply this paste to the areas on the metal pieces that will be joined using the brush. We have developed and are refining a variety of products of this sort.

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 is also much easier then welding it s a lot like using a glue gun. I needed a very big propane torch to raise the temperature of the parts enough to braze. A third method of applying brazing filler metal is to use a paste mixture of flux and filler metal powder.

A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides. Brazing a simple aluminium joint is easy enough but the rest didn t quite go to plan. Brazed metal can also be stronger then w. Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease.

Mix a small amount of flux with water to form a paste. Technically filler metals that melt above 840ºf 450ºc join by brazing instead of soldering. Use a torch that produces a high intensity flame. When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage.
