Mg alloy walkie-talkie casing

Mg alloy walkie-talkie casing:

Using magnesium alloy to make the housing of a walkie-talkie has the following advantages:

Lightweight and high strength: Magnesium alloy has a low density, lighter than aluminum alloy, but also has excellent strength and rigidity, which can achieve lightweight design for the walkie-talkie housing.

Corrosion resistance: The oxide film formed on the surface of the magnesium alloy can effectively prevent corrosion and oxidation, making the walkie-talkie housing have good corrosion resistance.

Good heat dissipation: Due to the high thermal conductivity of magnesium alloy, it can effectively promote the internal heat dissipation of the walkie-talkie, ensuring normal operation and service life of the equipment.

Good ductility: Magnesium alloy has good plasticity and processing performance, and can be processed and formed into various complex shapes according to needs to meet various design requirements for walkie-talkie housing.

The commonly used magnesium alloy grades for making walkie-talkie housings include AZ31B, AZ61A, and AZ91D. Among them, AZ31B is the most commonly used one, which is composed of 3% aluminum and 1% zinc, and has good machinability, strength, and corrosion resistance.

AZ61A and AZ91D add more aluminum and zinc, so they have higher strength and hardness, but are difficult to process and prone to cracking. Therefore, when choosing magnesium alloy grades, evaluation and selection should be based on the specific requirements and manufacturing processes of the walkie-talkie.

Generally, they are processed after leaving the factory.
