Description

Technical field

[0001] The invention relates to a magnesium alloy with light weight and higher specific rigidity, in particular to a magnesium alloy for die-casting and magnesium die-cast products using the alloy. Background technique

[0002] Among the alloys that have been widely used so far, magnesium alloys (hereinafter referred to as "Mg alloys") are not only light in weight and high in specific rigidity, but also well known as materials with strong electromagnetic wave shielding and thermal conductivity.

[0003] Among them, most of the Mg alloys for casting used in portable personal computers and mobile phones and other portable information electronic devices are mainly AZ91 alloys.

[0004] The AZ91 alloy has excellent strength, corrosion resistance, formability and other properties, and is widely used in die casting as a casting alloy with good balance.

[0005] However, the AZ91 alloy is not suitable for use in automobiles and two-wheeled vehicles that have high require...
