    Magnesium alloys are the lightest structural and hence suitable for application within the automotive industry, which has increased attention to the vehicle weight and fuel economy. Magnesium alloys supported by the Mg-Al system are studied extensively to be used in vehicle thanks to the load savings they supply and also for his or her excellent castability.

Master alloys

A master alloy is a base metal like aluminum, nickel, or copper combined with a comparatively high percentage of one or two other elements. It's manufactured to be used as raw materials by the metals industry, and that’s why we called master alloy semi-finished product. Master alloys are produced in various shapes such as ingot, waffle plate, rod in coils and etc.

There are lots of reasons for adding master alloys to a melt. One main application is composition adjustment, i.e. changing the composition of the liquid metal to realize the specified chemical specification. Another important application is structure control - influencing the microstructure of metal in the casting and solidification process so as to vary its properties. Such properties include mechanical strength, ductility, electrical conductivity, castability, or surface appearance. Counting on its application, a master alloy is usually also mentioned as "hardener", "grain refiner" or "modifier". 

Economical, technical, or both are common reasons for employing a master alloy rather than a pure metal. Some elements show high losses - or poor yield - when added in pure form. Others won't dissolve in the least at the furnace temperature prevailing in a cast house. While, a master alloy often supplies the best solutionbecause it dissolves much quicker at lower temperatures, saving both valuable energy and production time.
