3C products -- Computer, Communication, Consum· erelectronic Products (Computer, Communication, consumer electronic products) is the fastest developing industry in the world. Digital technology has led to the emergence of various kinds of digital products. At 175 cC, the creep strength of AS41 alloy is significantly higher than that of AZ91 and AM60 alloy. For example, the corrosion resistance of high-purity AZ91HP magnesium alloy in salt spray tests is about 100 times that of AZ91C, exceeding that of die cast aluminum A380, and much better than that of low carbon steel. The research work invested in the early stage also includes magnesium alloy scale research, treatment and operation mechanism innovation research and other related content. Driven by the development trend of 3C products towards light, thin, short and small, the application of magnesium alloy has been growing continuously in recent years.
