OTHER PROPERTIES

Typical Hardness

O temper: 67 Rockwell E

H24 temper: 83 Rockwell E

•  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 plate and sheet, 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 radius indentor on 350mm span)

•  Surface Treatment

All the normal chromating, anodizing, plating, and finishing treatment are readily applicable. AZ31B also responds well to plasma electrolytic oxidation finishing.
