Brazing Sheet Aluminum

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.

Brazing sheet aluminum.

Use a torch that produces a high intensity flame. 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. While close it is just fancy solder. Apply this paste to the areas on the metal pieces that will be joined using the brush.

Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. Brazing requires less energy than welding and can be used to join dissimilar metals. Brazing is also much easier then welding it s a lot like using a glue gun. Brazed metal can also be stronger then welds.

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. T oo much oxygen or gas will blow the torch out so slowly adding oxygen to achieve optimum brazing flame is advised. These filler metals are available as wire or shim stock. Commercial brazing filler metals for aluminum alloys are aluminum base.

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. 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. Lynch metals is the largest stocking distributor of aluminum brazing sheet in north america with locations in union nj and anaheim ca.

We have developed and are refining a variety of products of this sort. 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 is a quick and inexpensive alternative to welding. Mix a small amount of flux with water to form a paste.

Brazing is similar to soldering but at higher temperatures.
