Magnesium is one of the lightest available metals and is commonly used in metallic alloys due to its light weight, strength, and corrosion resistance. The metal is used the production of many lightweight products requiring durability, such as laptops, cameras, and power tools. It can also be a sulfur removing agent when coined with molten iron.
Aug 03, 2018· The corrosion resistance of modern, high-purity magnesium alloys is better than that of conventional aluminium die-cast alloys. Magnesium components have many mechanical/physical property disadvantages that require unique design for appliion to automotive products. Although it’s tensile yield strength is about the same, magnesium has lower
5xxx Series Alloys – (non-heat treatable – with ultimate tensile strength of 18 to 51 ksi) These are the aluminum / magnesium alloys (magnesium additions ranging from 0.2 to 6.2%) and have the highest strength of the non-heat treatable alloys. In addition, this alloy series is readily weldable, and for these reasons they are used for a wide
availability and cost. Magnesium alloys being the lightest of all of the commonly used structural metals can be considered as one of very attractive candidates. Furthermore, magnesium alloys have other desirable such propertieshigher than for other alloys strength-
Magnesium alloys are used in a variety of engineering appliions. When looking for weight reduction without compromising overall strength magnesium alloys is most preferred. Magnesium alloys have been used as a replacement for some engineering plastics due to their higher stiffness, high recycling capabilities and lower cost of production.
• Solid Magnesium requires significant heat to melt • Melting point is the same as Aluminium • Melting must occur before opportunity to burn • Newer alloys (WE43, Elektron 21) are more “flame resistant” than older alloys • Magnesium used in Aircraft Engines. More recently , resurgence of interest in Magnesium for interior appliions
