AZ31B alloy belongs to Mg-Al-Zn series magnesium alloy, which cannot be strengthened by heat treatment. It has the characteristics of moderate strength, good weldability and good machining performance, etc. It is the most widely used magnesium alloy at present, and has many applications in the structural parts of aerospace, transportation, electronic communication and other fields.
Magnesium alloys can be divided into two categories according to the manufacturing process — wrought magnesium alloys and cast magnesium alloys. AZ31B magnesium alloys are wrought magnesium alloys with good mechanical properties. They are mainly used for automotive parts, machine parts and communications. equipment etc.
