4000 Series Aluminum Alloy Sheet/Coil 4006 4007 4015
Trace elements of silicon-based aluminum alloy, show high silicon content, low melting point, good melt flow, easy to fill shrinkage, and will not make the final product brittle, so mainly used in the manufacture of aluminum alloy welding added materials, such as brazing plate, welding rod and wire. Alloys containing about 5% silicon are black gray after anodized, so they are suitable for building materials and decorative parts.
