Aluminum 4047 alloy coil strip is a non-heat treatable wrought alloy type with good corrosion resistance. It is a filler alloy, and is quite similar to aluminum 4043 except for the higher silicon content in aluminum 4047 alloy. The higher silicon content provides improved fluidity during welding process with smooth finishes, as well as reduced shrinkage. It is suitable for elevated temperature operations.
