AA 4000 Series (Aluminum Silicon Wrought Alloys)
we can ensure that the steel we source is tailored to the needs of our valued customers.
AA 4000 Series (Aluminum Silicon Wrought Alloys) line

4000 series aluminum grades contain 3.6-13.5% silicon and small amounts of copper and magnesium. 

Silicon is the main alloying element; it lowers the alloy's melting point, resulting in improved fluidity during the molten state. This makes the 4000 series grades good filler material for welding and brazing.

Some grades under the 4000 series are heat-treatable depending on the amounts of copper and magnesium in the alloy. 

Such additions will give a favorable response to heat treatment. 

The heat-treatable grades can be used for welding if combined with the aluminum grades under a heat-treatable series.

Applications of AA 4000 Series

The 4000 series aluminum rod is represented by the 4A01 4000 series aluminum plate, which belongs to the series with higher silicon content. 

Usually the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical zero-removing cattle, forging materials, welding materials; low melting point, good corrosion resistance, product description: has the characteristics of heat resistance and wear resistance.

1. 4032 has good heat resistance and wear resistance, and a small coefficient of thermal expansion. piston, cylinder head
2. 4043 has less solidification shrinkage, and it is gray in natural hair color after sulfuric acid anodizing treatment. Fusion wiring, building panels
