Magnesium Elektron Elektron® 43 Magnesium Wrought Alloy
Categories:	Metal; Nonferrous Metal; Magnesium Alloy
Material Notes:	High strength wrought Mg alloy available as rolled plate, forging feedstock, and extrusions. It is a wrought evolution of the casting alloy Elektron WE43. Elektron 43 uses zirconium grain refining and has successfully undergone flammability tests by the FAA for use in aircraft seat frames. It develops maximum strength in the T5 condition.
Vendors:	Magnesium Elektron is the world leader in high strength magnesium alloys in rolled, extruded and cast forms. Phone (303) 589-3189 or visit www.magnesium-elektron.com.
