Lanthanum, yttrium, cerium, gadolinium, neodymium, dysprosium, etc. give alloys and steels the requisite characteristics.
Mischmetal is a mixture of rare earth metals whose main components are cerium, lanthanum, neodymium, and praseodymium. It is an extremely reactive substance and forms alloys with a large number of elements.
Tungsten powders for engineering ceramics and hardmetal applications are available in customized particle sizes.
They are used in alloys in the steel processing industry.
