    Hot rolled AZ31B Magnesium alloy plate sheet polished surface with fine flatness, cut-to-size as per ASTM B90/B90M-15

    AZ31B is a wrought magnesium base alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. Increased strength is obtained by strain hardening with a subsequent partial anneal (H24 and H26 tempers). Our sheet and plate’s size range is:

    Sheet: thickness from 0.5mm to 6mm; Max. width is 600mm; Max. length is 6000mm;

    Plate: thickness from 6 mm to 200mm; Max. width is 2000mm; Max. length is 6000mm;

    Block: We can supply precut blocks according to customer’s requirements.


    APPLICATIONS

    Sheet and plate in AZ31B find application in medium strength service at temperatures below 150°C. Diverse uses including aerospace, aircraft, concrete tools, 3C (cell phone / camera / computer), speaker cones and textile machinery can all benefit from light weight AZ31B.


    AZ31B is non-magnetic and has high electrical and thermal conductivity filling the requirements for RFI and EMI shielding in the electronics and computer industries.


    Superplastic forming of AZ31B sheet at elevated temperatures allows production of a wide variety of intricate parts for automotive uses. Monocoque construction utilizing formed sheet can be adapted to many commercial applications.

    OTHER PROPERTIES

    Typical Hadness

    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 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)
