Elektron (alloy)

Elektron is the registered trademark of a wide range of magnesium alloys manufactured by a British company, Magnesium Elektron Limited.

Not to be confused with electrum, a naturally occurring alloy of gold and silver.
For other uses, see Elektron (disambiguation) and Electron (disambiguation).

There are about 100 alloys in the Elektron range, containing from 0% to 9.5% of some of the following elements in varying proportions: aluminium (< 9.5%), yttrium (5.25%), neodymium (2.7%), silver (2.5%), gadolinium (1.3%), zinc (0.9%), zirconium (0.6%), manganese (0.5%) and other rare-earth metals.

Varying amounts of alloying elements (up to 9.5%) added to the magnesium result in changes to mechanical properties such as increased tensile strength, creep resistance, thermal stability or corrosion resistance. Elektron is unusually light and has a specific gravity of about 1.8 compared with the 2.8 of aluminium alloy, or the 7.9 of steel. Magnesium's relatively low density makes its alloy variants suitable for use in auto racing and aerospace engineering applications.
