Brazing Sheet Aluminum

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 sheet aluminum.

Lynch metals is the largest stocking distributor of aluminum brazing sheet in north america with locations in union nj and anaheim ca. Brazing is similar to soldering but at higher temperatures. We have developed and are refining a variety of products of this sort. Brazing requires less energy than welding and can be used to join dissimilar metals.

Apply this paste to the areas on the metal pieces that will be joined using the brush. These filler metals are available as wire or shim stock. 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. When compared to welding equipment aluminum brazing equipment is inexpensive portable and does not require high amounts of voltage.

Brazing is a quick and inexpensive alternative to welding. Use the right brazing rod material for the metal used in your project. Brazed metal can also be stronger then welds. T oo much oxygen or gas will blow the torch out so slowly adding oxygen to achieve optimum brazing flame is advised.

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. 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 is also much easier then welding it s a lot like using a glue gun. 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.

Mix a small amount of flux with water to form a paste. While close it is just fancy solder. 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.

Use a torch that produces a high intensity flame.
