Magnesium EV31A
EV31A magnesium is a magnesium alloy. Cited properties are appropriate for the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. EV31A is the ASTM designation for this material. M12310 is the UNS number.
It has a very high melting temperature and a moderately low ductility among magnesium alloys.
Miji Magnesium focuses on magnesium alloy materials and custom non-ferrous metal solutions. We support buyers with material selection, custom size cutting, CNC machining, inspection documents, export packing and international shipment. For EV31A magnesium alloy requirements, please send grade, form, dimensions, quantity, tolerance, drawing and destination country to sales@mijimg.com.
