Aluminium alloy 4047 is an aluminum silicon brazing or filler alloy with good corrosion resistance. Alloy 4047 has a higher silicon content than alloy 4043 with 11-13% silicon, AL 4047 is generally used when high fluidity and reduced shrinkage and hot cracking is required for specific repairs or manufacturing.

Aluminium alloy 4047 is suitable for use at elevated temperatures making it particularly useful in the automotive industry for parts and engine blocks. Other applications include welding filler wires, liners such as laser welded covers for microwave integrated circuits, and other similar devices.
