Magnesium alloys have excellent corrosion resistance. As mentioned earlier, magnesium is widely used in the manufacture of mobile phones, laptops, cameras and other electronic components due to its light weight and good mechanical and electrical properties. Magnesium alloys feel a bit like plastic. Rest assured, there will be plenty of other PC makers coming out with Blue Magnesium laptops. Moving to magnesium alloys makes you more concerned about weight and feel. Die-cast magnesium parts generally outperform plastic: stronger and more wear-resistant than plastic. Excellent stiffness like plastic usually requires significant reinforcement.

Process analysis: Laptop case made of magnesium alloy ME20. This part has a complex structure and high dimensional accuracy requirements, so it is integrally milled from a magnesium alloy plate. Magnesium machining is very different from traditional aluminum alloy machining in terms of tool selection, cutting parameter selection, cutting plan selection, cutting fluid selection, anti-corrosion measures, and chip treatment.
