Magnesium alloy die casting advantages

Magnesium alloy die casting advantages

High productivity;

High precision;

Good surface quality;

Fine casting grains;

Die-casting products with thin walls and complex structures. 0.6 mm thickness

Magnesium alloy die casting compared with aluminum alloy die casting:

50% higher productivity;

Steel die can be used to extend service life;

Lower latent heat, saving energy;

Good machinability;

Mold cost saving 50%;

The melt has a higher fluidity.

Magnesium alloy die casting also has some disadvantages, such as:

Due to the high liquid filling rate and solidification rate, it is easy to produce involution pores. Feed, exhaust and cold material processing is particularly important.

Casting can not be too thick, the wall thickness can only be limited to a certain size;

Cheap die-casting alloy with limited mechanical properties;

The limited variety of die-casting alloys available; The general mobile phone industry uses AZ91D

Due to the fine grain size of the casting, the creep resistance is poor.

Creep resistant Mg-Al-Re magnesium alloys have poor castability and are expensive.

No heat treatment;

Not suitable for welding. A protective gas is needed
