Mg alloy laptop case

Mg alloy laptop case 

Magnesium alloy is a highly suitable material for manufacturing electronic product casings due to its lightweight, high strength, and corrosion resistance. The following are the main advantages of using magnesium alloy for laptop casings:

Lightweight: Magnesium alloy is a very light material, approximately 30% lighter than aluminum alloy, which can effectively reduce the overall weight of the laptop, making it more convenient for users to carry and use.

Toughness: Magnesium alloy has extremely high strength and stiffness, which can effectively protect the internal components of the laptop. Additionally, magnesium alloy also possesses good impact resistance, which can reduce the risk of laptop damage.

Corrosion resistance: Magnesium alloy has excellent resistance to corrosion, making it less susceptible to oxidation or rust, which can effectively extend the lifespan of the laptop.

Good heat dissipation: Magnesium alloy has good thermal conductivity, which enables quick heat dissipation during use, effectively preventing laptop malfunction due to overheating.

Common magnesium alloy materials include AZ31, AZ61, AZ91, etc. Among them, AZ31 is a commonly used magnesium alloy material composed of 3% aluminum and 1% zinc, with good strength and corrosion resistance performance. AZ91 is a magnesium alloy with higher aluminum content, possessing higher strength and stiffness.

The common methods for processing magnesium alloy laptop casings include:

Casting: using die casting, gravity casting, low-pressure casting, etc., to manufacture parts with the desired shape.

Stamping: placing the metal sheet in a punch press and using a mold to stamp it into the desired shape.

CNC machining: using CNC machines to precisely cut, drill, punch, and process according to design drawings.

Stretch forming: heating the flat plate with grooves or protrusions to a certain temperature and using molds to stretch it into the desired shape.

In terms of price, magnesium alloy is relatively expensive due to its complex production process and high raw material costs. However, due to its advantages of being lightweight, tough, corrosion-resistant, and possessing good heat dissipation, more and more manufacturers are choosing to use magnesium alloy casings. Different processing methods will also affect the price. For example, casting is relatively inexpensive, while CNC machining is relatively costly. Overall, magnesium alloy laptop casings are typically priced higher than similar products made of aluminum alloy or plastic. Please feel free to inquire about pricing.
