32D5 High Strength Magnesium Alloy Az80 Astm For Automobile Industry

Damping And Shock Absorption High Strength Magnesium Alloy For Automobile Industry

Introduction:

Magnesium alloys are alloys based on magnesium and other elements. Its characteristics are: low density (about 1.8g/cm3), high strength, large elastic modulus, good heat dissipation, good shock absorption, larger impact load capacity than aluminum alloy, and good corrosion resistance to organic substances and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium.

Magnesium alloys have the characteristics of low density, high specific strength and specific stiffness, good dimensional stability, good thermal conductivity and electrical conductivity, vibration absorption and easy processing, so magnesium alloys are one of the competitive lightweight materials.

Features:

Due to the good thermal conductivity and low cutting force of magnesium alloys, the heat dissipation rate during processing is very fast, so the tool life is long and the amount of sticking to the tool is small, which can reduce tool costs and shorten the downtime required for tool replacement.

Because magnesium is easy to cut, its chip breaking performance is very good, and generally only one finishing operation is needed to achieve the required final surface finish.

Processing performance advantage:

1. The melting cost is only 2/3 of that of aluminum:

2. Excellent die-casting formability: magnesium alloys can be die-casted to manufacture complex parts and ultra-thin shell parts, the thinnest can reach 0.45mm (ABS plastic is 1.2-2mm, aluminum alloy is 1.5-2mm), and the surface quality of magnesium castings and the The appearance is obviously better than that of aluminum: the affinity of magnesium die-casting with the mold is much lower than that of aluminum, and the life of the mold is more than twice that of aluminum.

3. The production efficiency of die casting is 25% higher than that of aluminum, metal mold casting is 300-500K higher than aluminum, and lost foam casting is 200% higher than aluminum.

4. Good cutting performance: magnesium alloy has low hardness and good cutting performance. The cutting resistance is only 56% of aluminum alloy and 43% of brass. High cutting speed and cheap cutting can be used during processing. Cutting tools, low tool consumption. And without grinding and polishing, you can get a very smooth surface with cutting fluid.
