Brazing Sheet Aluminum

Brazing is similar to soldering but at higher temperatures.

Brazing sheet aluminum.

Use a torch that produces a high intensity flame. 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 requires less energy than welding and can be used to join dissimilar metals. Mix a small amount of flux with water to form a paste.

Always clean the aluminum with an abrasive such as a sanding disk or wire wheel before starting your brazing process to ensure a proper bond. Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs. Commercial brazing filler metals for aluminum alloys are aluminum base. While close it is just fancy solder.

Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage. Brazing is also much easier then welding it s a lot like using a glue gun. Brazing is a quick and inexpensive alternative to welding.

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. T oo much oxygen or gas will blow the torch out so slowly adding oxygen to achieve optimum brazing flame is advised. The equipment in this project can be bought for as little as 30 dollars.

We have developed and are refining a variety of products of this sort. Brazing brazing sheet some aluminum sheet products are made up of a strong core alloy that is clad with a thin layer of high silicon alloy which has a much lower melting point than the core. Brazed metal can also be stronger then welds. Also it is not brazing it is still soldering brazing by definition occurs at over 450c most of these filler alloys zinc and aluminum melt around 390c.

Use the right brazing rod material for the metal used in your project.
