Aluminum 4047

About 4047 Aluminum Alloy (Al, Si, Fe, Cu, Zn, Mn, Mg)

4047 Aluminum Alloy is an aluminum silicon brazing or filler alloy with good corrosion resistance. The main difference between alloy 4047 and it’s AL4043 counterpart is its higher silicon content. With 11-13% silicon, AL 4047 is generally used when high fluidity and reduced shrinkage and hot cracking is needed for specific repairs or manufacturing. Additionally, 4047 is suitable at elevated temperatures making it particularly useful in the automotive industry for parts and engine blocks. Other applications include welding filler wires, leak tight joints, housing requirements, window frames, liners such as laser welded covers for microwave integrated circuits, and other similar devices.

Brazing is a metal joining process whereby a filler metal is heated above the melting point and distributed between two or more close fitting parts by capillary action. The filler metal is brought slightly above its melting ( liquidus ) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then cooled to join the workpieces together. It is similar to soldering, except the temperatures used to melt the filler metal are higher for brazing.  A variety of alloys are used as filler metals for brazing depending on the intended use or application method. In general, braze alloys are made up of 3 or more metals to form an alloy with the desired properties. The filler metal for a particular application is chosen based on its ability to: wet the base metals, withstand the service conditions required, and melt at a lower temperature than the base metals or at a very specific temperature.
