New supermagnesium alloys are stronger than aluminum and cheaper than carbon fiber

Allite (USA) has developed unique ultra-strong magnesium alloys that are lighter and tougher than aluminum and less expensive than carbon fiber.

Previously, magnesium alloys were used exclusively in the military and aerospace industries, but it seems that recently they have found quite peaceful applications. At the upcoming Interbike 2018 exhibition in Reno, Nevada, USA, from September 18 to September 20, a bicycle frame made of supermagnesium alloys will be presented.

Allite has developed three versions of the compound - AE81, ZE62, WE54. Each of them has its own characteristics - the ability to weld, toughness, heat resistance, corrosion resistance, wear resistance, hardness and conductivity. In particular, these are the only magnesium alloys today that melt rather than burn at a temperature of 650 ° C.

According to the developers, their alloys have the lowest carbon content, which makes them much cheaper than their counterparts. In addition, they are completely recyclable.

Prospects for the conversion of purely "military" alloys until recently - the production of sports goods, drones, engine components for locomotives and even cases for smartphones.
