Alloy 4047 was originally developed as a brazing alloy to take advantage of its low melting point and narrow freezing range. In addition, it has a high silicon content which provides for increased fluidity and reduced shrinkage.

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.
