AM50A Magnesium Alloy AM50A Magnesium Alloy Price AM50A Magnesium Alloy Performance
Belonging to the category of cast magnesium alloys, it mainly relies on pressure mold casting and post-processing methods for processing, and can change its appearance through surface methods such as electrophoresis. The characteristic is high strength and good corrosion resistance, mainly used for the shell of electrical products, small-sized thin or irregular brackets, etc. A represents metal aluminum Al, Z represents metal zinc Zn, 9 represents aluminum content of 9%, 1 represents zinc content of 1%, and D is the identification code. Application scope of GB/T5153-2003: Magnesium alloy is widely used in portable equipment and the automotive industry to achieve lightweight magnesium alloy castings.
Although the specific gravity of magnesium alloy is heavier than that of plastic, its strength and elasticity per unit weight are higher than those of plastic. Therefore, in the case of components with the same strength, magnesium alloy components can be made thinner and lighter than plastic components. In addition, due to the higher specific strength of magnesium alloys compared to aluminum alloys and iron, the weight of aluminum or iron components can be reduced without reducing their strength.
Relative strength ratio of magnesium alloy (strength to mass ratio). The specific stiffness (the ratio of stiffness to mass) is close to that of aluminum alloy and steel, and much higher than that of engineering plastics.
Within the elastic range, magnesium alloys absorb half the energy of aluminum alloy components when subjected to impact loads, thus exhibiting excellent seismic and noise reduction performance.
Magnesium alloy has a lower melting point than aluminum alloy and better die-casting performance. The tensile strength of magnesium alloy castings is comparable to that of aluminum alloy castings, generally reaching 250MPA and over 600 MPa. The yield strength and elongation are not significantly different from aluminum alloys.
Magnesium alloy also has good corrosion resistance, electromagnetic shielding performance, and radiation resistance, and can achieve 100% recycling and reuse of magnesium alloy castings.
The stability of magnesium alloy parts is higher than that of high-pressure castings, and the dimensional accuracy of the casting line is higher, which can be used for high-precision mechanical processing.
Magnesium alloy has good die-casting performance, with a wall thickness of up to 0.5mm for die-casting parts. Adapt to manufacturing various types of die-casting parts for automobiles
According to the forming method, it can be divided into two categories: deformed magnesium alloys and cast magnesium alloys.
