4007 aluminum is a 4000-series aluminum alloy. The main alloying addition is silicon. 4007 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-4007. Additionally, the EN chemical designation is AlSi1,5Mn. And the UNS number is A94007.

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 pipes 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 pipe means this is the highest value in the relevant set. A half-full pipe means it's 50% of the highest, and so on.

Features

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.
