The mold aluminum plate needs good mechanical properties, strong usability, easy processing, and most importantly, a certain high strength heat treatment. According to the different uses of the mold and their respective characteristics, the mold aluminum plate also needs to have special requirements such as corrosion resistance and oxidation resistance.
According to the performance requirements of the mould aluminum plate, among the 1-8 series aluminum plates, the aluminum plates that can be used for mold manufacture mainly include medium hardness 5/6 series alloys and stronger 2/7 series alloys. Series 5 is an aluminum alloy with magnesium as the main alloying element, also known as magnesium aluminum alloy. Its alloy states mainly include the O state, HXX, and HXXX states. The 6 series aluminum plate is an extruded alloy with Al-Mg-Si added. At present, more than 70% of the aluminum extrusion materials in the world are produced from 6 series alloys.
5083 aluminum plate belongs to the hot-rolled aluminum plate series. The 5083 aluminum plate produced by Signi Aluminum Industry adopts the continuous casting and rolling process technology. It has good forming performance, corrosion resistance, weldability, and oxidation deep processing performance. It is the best choice for aluminum plate for mold making.
After the heat treatment and pre-stretching process of 6061 aluminum plate, although its strength cannot be compared with 2XXX series or 7XXX series, it has many characteristics of magnesium and silicon alloys, and has good processability and excellent welding characteristics. In addition, its electroplating, corrosion resistance, high toughness and no deformation after processing, dense and defect-free material, easy to polish, easy to color film, excellent oxidation effect.
The O and T4 states of 6082 aluminum plate are suitable for bending and forming. The T5 and T6 states are suitable for molds with good machinability requirements. 6082 aluminum plate has better corrosion resistance and wear resistance. It has good processing performance and excellent welding characteristics. In addition, its electroplating, corrosion resistance, high toughness, no deformation after processing, dense and defect-free materials, can also be used in tank car bodies and other products with higher requirements on the performance of the finished product.
The above alloy aluminum plates have medium strength, good corrosion resistance and weldability, and can be widely used in various industrial abrasive tool structures requiring certain strength.
