Aluminum sheet metal for mold

The aluminum sheet metal for the mold is a special aluminum plate because it has higher requirements for the performance of the aluminum plate. These requirements include: high strength, excellent heat treatability, good mechanical properties, ease of processing, extreme corrosion and oxidation resistance. So what are the aluminum plate grades that meet these conditions? Among the 1-8 series aluminum sheet metals, those for mold manufacturing mainly include a medium hardness 5/6 series alloy and a relatively hard 2/7 series alloy. Let's talk about the 5 series and 6 series of sheets here.

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, the HXX and the HXXX state. The 5052 aluminum sheet metal belongs to the hot rolled aluminum plate series. The 5052 aluminum plate produced by Haomei adopts the processing technology of continuous casting and rolling. It has good processing properties, corrosion resistance, weldability and deep processing performance of formed aluminum sheet. It is a good choice for aluminum plate for mold making.

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. After the heat treatment pre-stretching process of Haomei 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, compact and defect-free materials, 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 sheet metal is better in corrosion resistance and wear resistance. 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.
