The difference between the 4047 aluminum plate and the 6061 aluminum alloy is that the metal elements are different. The 4047 alloy is mainly composed of silicon, and the 6061 aluminum is mainly composed of magnesium and silicon.
4047 belongs to one of the 4 series alloys. The 4 series aluminum alloy is an aluminum alloy with silicon as the main alloying element. Most alloys are heat-treated non-strengthen aluminum alloys, which refer to alloys containing Cu, Mg and Ni, and welding heat treatment After the alloy absorbs certain elements, it may be strengthened by heat treatment. This series of alloys has high silicon content, low melting point, good melt fluidity, and ultimately will not cause brittleness of the product, so it is mainly used to make additional materials for aluminum alloy welding, such as brazing plates, welding rods and welding wires.
In addition, due to the high wear resistance and high temperature resistance of some of 4047 aluminum alloy sheet, they are also used to make pistons and heat-resistant parts. The alloy containing about 5% of silicon is black and gray after being anodized, so it is suitable for building materials and decorative parts.
The main alloying elements in 6000 series aluminum alloys represented by 6061 are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. It is widely used in various industrial structural parts that require certain strength and high corrosion resistance, such as manufacturing trucks, tower buildings, ships, trams, railway vehicles, furniture, etc.
