Super Magnesium alloy: Lighter than aluminum and cheaper than carbon fiber

• by Loz Blain

Allite Super Magnesium, an alloy previously only available to military and aerospace but now being targeted at a range of other applications, is lighter and stiffer than aluminum, but not as expensive as carbon fiber.

Allite hopes its new magnesium alloys, which are officially launching at next week's Interbike cycling expo in Reno, will create a niche somewhere beneath carbon fiber in the lightweighting world.

While each of the three alloys – AE81, ZE62 and WE54 – has its own specific strengths (weldability, forgeability and high temperature work, respectively), they're all highly resistant to corrosion, fatigue and wear, with excellent hardness and electrical insulation properties, according to the manufacturer. And they're the only magnesium alloys on the market that will melt, instead of burning, under a 1,200° F (650° C) flame.
