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. 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. Apply this paste to the areas on the metal pieces that will be joined using the brush. Brazing requires less energy than welding and can be used to join dissimilar metals.
These filler metals are available as wire or shim stock. Brazing is also much easier then welding it s a lot like using a glue gun. We have developed and are refining a variety of products of this sort. Commercial brazing filler metals for aluminum alloys are aluminum base.
While close it is just fancy solder. 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. Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs.
Use the right brazing rod material for the metal used in your project. 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. Use a torch that produces a high intensity flame. 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.
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. Brazing is a quick and inexpensive alternative to welding. Brazing is similar to soldering but at higher temperatures.
