Magnesium Alloy and Magnesium Master alloy>

Magnesium master alloy, mainly refers to rare earth magnesium master alloy (rage earth master alloy), is a material with metallic properties composed of rare earth element and magnesium element, also known as master alloy, such as magnesium yttrium master alloy, magnesium gadolinium master alloy, The basic purpose of magnesium master alloy is as rare earth additive.Magnesium master alloy also contain a material composed of non-rare earth element and magnesium element,such as Magnesium nickel master alloy, magnesium zirconium master alloy, magnesium calcium master alloy,magnesium silicon master alloy and so on.

Magnesium alloys are being used in many structural applications in the automotive, aerospace, electronics and other industries. The rare earth element are effective alloying elements for magnesium alloys, especially in high resistance to high temperatures. There are a few kinds of rare earth magnesium alloys, for example, Elektron WE43, Elektron RZ5, WE54, AE42, AE41 etc. It is very difficult to directly produce the special magnesium alloy contained rare earth because there is a large difference between magnesium (1.78g/cm3 ) and rare earth ( ~ 7.8g/cm3 ) in density. Also, it is very difficult to alloy because their molten point is very different, which magnesium is about 650 degree and rare earth are above 1100 degree. Since the lack of rare earth magnesium alloys, The application in high temperature, creep resistance, high strength and corrosion resistance is deeply limited. 

The magnesium alloys containing neodymium element, for example, show a higher strengthening effect than that contained cerium. And alloy containing yttrium shows a higher strengthening effect and creep resistance effect than neodymium in magnesium alloys. The strength properties of Mg alloys with rare earth metals are connected to a great extent with the content of RE in magnesium, especially, the solubility of the rare earth metals in solid Mg. Therefore, the success in developing a series of rare earth magnesium master-alloys will be very important for the wide application of magnesium alloys.

Magnesium master alloy is a good way to produce the magnesium alloy containing rare earth. You just need to add the magnesium master alloy when producing the magnesium alloys. And then you can get the magnesium alloys containing the rare earth.
