Among the 1-8 series aluminum sheets, the aluminum sheets used for mold manufacturing mainly include a medium hardness 5/6 series alloy and a relatively hard 2/7 series alloy. The 5 series is an aluminum alloy with magnesium as the main alloying element, also known as magnesium aluminum alloy, and its alloy state mainly includes the O state, HXX and HXXX states. The 6-series aluminum plate is an extruded alloy to which Al-Mg-Si element is added. Currently, more than 70% of the aluminum extrusion processed materials in the world are produced using a 6-series alloy.
The 5083 aluminum plate belongs to the hot rolled aluminum plate series. The 5083 aluminum plate produced by Mingtai Aluminum Co., Ltd. adopts the processing technology of continuous casting and rolling, has good forming and processing properties, corrosion resistance, weldability and deep processing performance, and is the best choice for aluminum plate for mold making.
After the heat treatment pre-stretching process of Mingtai Aluminum 6061 aluminum plate, its strength can not be compared with 2XXX series or 7XXX series, but its magnesium and silicon alloy have many characteristics, and it has good processing performance and excellent welding characteristics. Moreover, it has high electroplating property, corrosion resistance, high toughness, no deformation after processing, compact material without defects, easy polishing, easy filming, and excellent oxidation effect.
The O and T4 states of the 6082 aluminum plate are suitable for bending and forming applications, and the T5 and T6 states are suitable for molds with good machinability requirements. 6082 aluminum plate is better in corrosion resistance and wear resistance. Has good processing properties, excellent welding characteristics. Moreover, it has high electroplating property, corrosion resistance, high toughness and no deformation after processing, and the material is dense and has no defects. It can also be used in products with high requirements on the performance of finished products such as tank car bodies.
The above alloy aluminum plate has medium strength, good corrosion resistance and weldability, and can be widely applied to various industrial abrasive structural parts requiring a certain strength.
