Magnesium alloy is a lightweight, high-strength and corrosion-resistant metal material that is very suitable for manufacturing electronic product casings. The advantages of magnesium alloy tablet computer shells are as follows:
Lightweight: Magnesium alloy is a very light material, about 30% lighter than aluminum alloy, which can effectively reduce the overall weight of the tablet computer, making it more convenient for users to carry and use.
Strong and tough: Magnesium alloy has extremely high strength and stiffness, which can effectively protect the internal components of the tablet computer. At the same time, magnesium alloy also has good impact resistance, which can reduce the risk of damage to the tablet computer.
Corrosion-resistant: Magnesium alloy has excellent anti-corrosion performance and is not easily oxidized or rusted, which can effectively extend the service life of the tablet computer.
Good heat dissipation: Magnesium alloy has good thermal conductivity, which can quickly dissipate heat during use, effectively preventing the tablet computer from malfunctioning due to overheating.
The specific choice of magnesium alloy grade depends on the manufacturer and product design. Generally speaking, common magnesium alloy materials include AZ31, AZ61, AZ91, etc. Among them, AZ31 is a commonly used magnesium alloy material, which is composed of 3% aluminum and 1% zinc, and has good strength and corrosion resistance. AZ91 is a magnesium alloy with a higher aluminum content, which has higher strength and stiffness.
Common processing methods for magnesium alloy tablet computer shells mainly include:
Casting: Use methods such as die casting, gravity casting, and low-pressure casting to manufacture parts in the required shapes.
Stamping: Place the sheet metal in a stamping press and use a mold to stamp it into shape.
CNC machining: Use a CNC machine tool for precise cutting, drilling, punching, etc. according to the design drawings.
Stretch-forming: Heat the flat plate with grooves or protrusions to a certain temperature, and use a mold to stretch it into shape.
In terms of price, magnesium alloy is relatively expensive because of its complex production process and high raw material prices. However, due to its advantages such as lightweight, strong and tough, corrosion-resistant and good heat dissipation, more and more manufacturers choose to use magnesium alloy casings. The use of different processing methods will also affect the price. For example, casting costs are relatively low, while CNC machining costs are relatively high. Overall, the price of magnesium alloy tablet computer shells is usually higher than that of similar products made of aluminum alloy or plastic.
