Magnesium alloy plate/sheet AZ31B

Magnesium Alloy AZ31B Properties     Applications AZ31B is used in a variety of aerospace applications and general commercial applications requiring good properties and high strength to weight ratio.   Machinability 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.   Welding AZ31B is best welded by the inert gas tungsten arc and metal arc methods.   Annealing 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.     Physical Properties   Density: 1.78   Coefficient of thermal expansion: 26.8 x 10-6K-1   Specific heat: 1040 Jkg-1k-1   Thermal conductivity: 76.9Wm-1k-1   Electrical resistivity: 92nΩm   Modulus of elasticity: 45 x 109Pa   Poissons ratio: 0.35   Melting range: 566 - 632°C     Size   Sheet thickness :1-6mm Width:600mm max Length:6000mm   Plate thickness:10-200mm Width:2500mm max Length:6000mm max   Coil thickness:0.5-2.7mm Width:240mm   If you have any requirments,pls contact me with below information:      Irene Tel:86-353-2590220 Skype/MSN:irene1041
