Available Dimensions

AZ31B

E-FORM

E-FORM (Mg sheet with high formability at low temperature)

Remarkably improved formability at low temperature compared to AZ31B

Remarkably increased LDH (Limit Dome Height) in Erichsen test

Reduced forming temperature from 250℃ to 150℃

  • AZ31B

    LDH : 2.5~3.8mm

  • New alloy (E-form)

    LDH : 7~9mm

As a result of part forming test, lowest forming temperature reduced from 250 to 150 ℃

Alloy Room Temp. 100 ℃ 150 ℃ 200 ℃

E-Form
Remark Cracks on both Rare cracks on E-Form No crack on E-Form No crack on E-Form

HEAT SINKER (Mg sheet with high thermal conductivity and formability)

Higher thermal conductivity compared to AZ31B and AZ61(Over 160% of AZ31B and 200% of AZ61)

POSNOBLE3 (Mg sheet with high corrosion-resistance and formability)

10 times superior corrosion resistance compared to AZ31B (at the same level as AL7075)

Good formability
