Rare Earth Alloys

Magnesium is an important structural metal. It is 1.5 times lighter than aluminum and 4 times lighter than steel.

Current world output of Mg is ~1.2 million tons.

Magnesium Rare Earth Alloy "Mg-Y" contains high percentages of yttrium and neodymium. It is flame resistent, does not burn, also 1.5 times lighter than aluminum and 4 times lighter than steel.

Mg-Y is high strength, easy machining material for high performance components in increased temperature applications.

It replaces high-strength aluminium alloys in applications such as light weight parts for vehicles, aerospace, engines.

Typical Composition of Mg-Y

Yttrium: 3.7-4.3%
Neodymium: 2.0-2.5%
Zinc: max. 0.06%
Zirconium: 0.2-1.0%
Other Rare Earths: 0.3-1.0%
Manganese: max. 0.03%
Copper: max 0.02%
Iron: max. 0.005%
Nickel: max 0.0020%
Other Elements, each: max 0.01%
Magnesium: remainder
