Custom 4047 perforated aluminum sheet：4047 aluminum is one of 4000 series alloys. 4 series aluminum alloys are aluminum alloys with silicon as the main alloying element. Most of the alloys are heat-treated non-strengthable aluminum alloys, which refer to alloys containing Cu, Mg, and Ni, as well as welding heat treatment strengthening After the alloy has absorbed certain elements, it may be strengthened by heat treatment. Because of the high silicon content, low melting point, good melt fluidity, and the final product will not be brittle, this series of alloys are mainly used to make aluminum alloy welding additives, such as brazing plates, welding rods and welding wires. In addition, due to the high wear resistance and high temperature resistance of some of this series of alloys, they are also used to make pistons and heat-resistant parts. The alloy containing about 5% of silicon is black-gray after anodizing and coloring, so Custom 4047 perforated aluminum sheet is used as building materials and manufacturing decorative parts.

4047 alloy aluminium coil is a non-heat treatable wrought alloy type with good corrosion resistance. It is a filler alloy, and is quite similar to aluminium / aluminum 4043 except for the higher silicon content in 4047 aluminum 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.
