Master Alloys
In many instances the use of master alloys is the most effective way of introducing controlled levels of rare earth metal to more complex alloy systems. The principal reason for adding rare earth metals in this way, is due to the very high oxidation potential of RE metals and a good master alloy will control oxygen content and will stabilise metals that would normally oxidise in the atmosphere.
The use of a master alloy delivers the benefits of improved yields, together with extremely precise and reproducible rare earth additions. LCM master alloys are used in the manufacture of corrosion resistant steels, high temperature alloys and various specialised systems. For individual applications LCM engineers are able to advise on the most suitable master alloy composition.
