az31B Magnesium alloy sheet

Magnesium alloy sheet is widely used in aerospaceelectronics3Cchemical and other industries. The plate we produced has three size: thin(3-100mm), medium, and thick(300*700mm), and enjoys the advantages of no crack, no air hole, no slag, tissue uniform, good thermal conductivity, high strength, uniform grain and so on.

AZ31B has a very high machinability rating. As with any magnesium alloy, great care should be taken because this material is flammable. To avoid this potential hazard, positive cuts should be taken, as large chips are less likely to ignite. Flooding with lubricant is also required and good procedure should include constant monitoring of the operation by a machinist equipped with a magnesium fire arresting kit, such as black powder.

AZ31B is best welded by the inert gas tungsten arc and metal arc methods.

Stress relieve at 300 F for 30 to 60 minutes, followed by air cooling. For full annealing, heat AZ31B to 650 F and furnace cool slowly.
