Master Alloys

Aluminum master alloys are also commonly referred to as grain refiners, modifiers or hardeners, depending on their application. Master alloys are specific elements added to aluminum alloys to produce a particular alloy, modify a melt or to produce castings with desired mechanical properties, such as greater mechanical strength, ductility, castability or surface appearance. Applications like this are why master alloys can be a smart business solution to adjust the properties of certain aluminum products, whether for technical or economical reasons – or both.

Beck Aluminum markets and distributes the Master Alloy products of Aleastur Group. Aleastur Group produces a comprehensive range of master alloys for the aluminum casting industry at its production facilities in Spain and Bahrain.
