It originally received its standard designation in 1978.

The properties of 4007 aluminum include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph wires on the material properties cards further below compare 4007 aluminum to: 4000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full wire means this is the highest value in the relevant set. A half-full wire means it's 50% of the highest, and so on.

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.
