What are the main features of magnesium alloy plate die casting? Let's take a look!

Magnesium alloy plate castings are currently widely used die -casting materials. Magnesium alloy plate die -casting products are mainly used for lamps, automobiles, motors, household appliances and some communication industries. Some high -performance, high -precision, high tough aluminum alloy products are also used for large High demand industries such as aircraft and ships are mainly used in some parts of the instrument. The main characteristics of die -casting aluminum alloy are as follows:

1. Low density and high intensity.

2. It has good high temperature and room temperature mechanical properties, especially good impact toughness.

3. Good conductivity and thermal conductivity, mechanical cutting performance is also very good.

4. The surface has chemical stability and dense aluminum oxide film, so most aluminum alloy has good corrosion resistance in freshwater, seawater, nitrate and various organic compounds. Alkaline ion damage.

Magnesium alloy plates have good die -casting performance and surface roughness.

Features of magnesium alloy plate die casting

1. Magnesium weighs only 1.8g/cm3, aluminum alloy weighs 2.7g/cm3, magnesium alloy is 30%lighter than aluminum alloy, and 80%lighter than steel. Therefore, magnesium alloy becomes an ideal material for automobiles and portable electronic products.

2. Magnesium alloy plates have a good strength/weight ratio in metal and plastic engineering materials.

3. In the case of maintaining a good micro tissue, the wall thickness of magnesium alloy castings can reach 0.6mm, which cannot be achieved by plasticity under the same strength. The magnesium alloy is easy to die, and it is suitable for large -scale die -cast production (1.5 times the production speed can reach 1.5 times that of aluminum). In addition, the wear of magnesium alloy molds is lower than that of aluminum.

4. The damping magnesium has a good stagnation and elastic damping performance, which can absorb vibration and noise. When used as a device shell, it can reduce the transmission of noise to avoid impact and prevent dental damage.

The hardness of magnesium is twice that of aluminum, which is higher than most plastic. Magnesium has good pressure resistance.

6. High -electromagnetic interference magnesium alloy has a good function of shielding electromagnetic waves and is suitable for the production of electronic products.

7. Good cutting performance Magnesium cutting price is better than aluminum and zinc, making magnesium a more likely to cut metal material.

8. The magnesium alloy is smaller than the heat capacity, and the liquid cooling speed of the alloy is fast.

9. Magnesium alloy and mold steel are small and small, and it is not easy to stick to the mold.
