The sheet and plate shall conform to the tensile requirements in above Table unless other agreement is made between seller and purchaser. Mechanical Properties for sizes and tempers not shown in above Table shall be as agreed upon by seller and purchaser.
OTHER PROPERTIES
Typical Hadness
WELDABILITY
Excellent weldability with gas shielded arc using AZ61A (preferred) or AZ92A filler rod; post weld stress relief is required to prevent stress corrosion cracking. Resistance welding is excellent.
MACHINING
AZ31B, like all magnesium alloy sheet and plate, machines faster than any other metal. Providing the geometry of the part allows, the limiting factor is the power and speed of the machine rather than the quality of the tool material. The power required per cubic centimeter of metal removed varies from 9 to 14 watts per minute depending on machining operation.
DENT RESISTANCE
Weight for weight, AZ31B-H24 has proven to be superior to competitive materials in its resistance to denting at moderate energy levels.
Dent Resistance of 1mm Gauge Sheet (Dent depth in mm from 25mm spherical redius indentor on 350mm span)
