Magnesium and Magnesium Alloys

This article focuses on the variety of alloys, furnaces, and associated melting equipment and on the casting methods available for manufacturing magnesium castings. The casting methods include sand casting, permanent mold casting, die casting, thixomolding, and direct chill casting.

2019/12/23As with all magnesium alloys, special precautions must be taken when machining Working with AZ91D Designers of structural components must be aware of the creep limitations of magnesium alloys—generally with increasing temperature, the tensile strength, yield strength, and hardness of magnesium alloys decreases, while ductility increases

2020/8/20Magnesium processing, preparation of magnesium ore for use in various products. In its pure form, magnesium lacks sufficient strength for most structural applications. However, the addition of alloying elements improves its properties to such an extent that both cast and wrought magnesium alloys are widely used.

This invention relates to the melting of magnesium and magnesium base alloys in induction furnaces. When using induction furnaces for melting g metals and alloys, the composition of the lining of the furnace should be such that the constituents of the lining do not

AZ91D magnesium is a magnesium alloy. AZ91D is the ASTM designation for this material. M11916 is the UNS number. It can have a moderately low tensile strength among magnesium alloys. In addition, it has a moderately low electrical conductivity and a

Magnesium alloys are light weight and feature superior machinability and ease of casting. They are often anodized to enhance corrosion resistance. They are designated using the ASTM and SAE system in which the first part denotes the two main alloying elements in the alloy and the second part represents their percentages.
