More Information

Magnesium alloys are the lightest metal structural materials for engineering applications. They have become highly sought after in the automotive, aerospace, weapons, electronic and other industries. This is because of their low density, high specific strength, and stiffness, good damping characteristics, as well as excellent castability.

Especially in the automobile industry, magnesium alloys, such as an AZ31 magnesium metal plate and an AZ31 magnesium metal sheet, have replaced the steel, cast iron and even aluminum alloys. (Magnesium is the lightest of all structural metals, aluminum being 1.5 times heavier and steel being 4 times heavier.) It is used because it can reduce the weight of vehicles. This significantly contributes to fuel economy and reduces CO2 emissions.

AZ31 Magnesium alloy is the most ductile and the most popular amongst AZ wrought alloys (Mg-Al-Zn group). Although it is soft, this alloy offers a good combination of strength and ductility for structural application.

The AZ31 magnesium plate has many benefits and special characteristics which gives many AZ31 magnesium sheet uses.

For example, it absorbs vibration much longer while keeping dimensional stability. This gives it 4 to 5 times greater tool life. u It is up to 5 times more machinable than rolled aluminum. It can machine dry, without oil or chemicals.

Easier handling saves time and energy, eliminates surface machining, with no stress relief after the machining process. It has no warps and is dent resistant, with strong weldments (up to 95% of parent metal). It has minimum porosity, and it is easy to clean with a wide variety of chemical treatments. Some exist for corrosion protection, some for alteration of surface appearance, and some to provide a base for painting.

Magnesium sheet and plate AZ31 alloy find application in medium strength service at temperatures below 150C. Diverse uses include aircraft fuselage, concrete tools, cell phones, cameras, notebook computer cases, and textile machinery.
