APPLICATION
Those applications requiring a flat surface or high dimensional stability benefit from the use of magnesium tooling plate. Typical uses included jigs, fixtures, optical benches, vibration test equipment and inspection gauges. Magnesium Tooling Plate is non-magnetic and has high electrical and thermal conductivity filling many material requirements in the electronics and computer industries.
MAGNESIUM TOOLING PLATE is specially produced to provide a flat plate surface with moderate strength and ductility. The production process results in plate with exceptional dimensional stability in machining and remains stable over time. There is sufficient ductility for limited room temperature forming combined with weldability to allow the manufacture of a multitude of complex parts. Wrought magnesium tooling plate (Alloy AZ31B) has the following benefits and characteristics:
| DAMPING | Absorbs vibration for longer life, while retaining dimensional stability. |
| TOOLING | 4 to 5 times greater tool life. |
| FINISH | Up to 5 times more machinable than rolled aluminum. |
| COSTS | Machine dry, without oil or chemicals. |
| WEIGHT | Easier handling saves energy and time. |
| FLATNESS | Eliminates surface machining. |
| STABILITY | No stress relief after machining; no warps and is dent resistant. |
| WELDING | Strong weldments up to 95% of parent metal, with minimal porosity. |
| ALKALI-RESISTANT | Makes for easy cleaning. |
| CORROSION RESISTANT | A wide variety of chemical treatments exists for corrosion protection, alteration of surface appearance, and to provide a base for painting. Basic engineering precautions averts galvanic corrosion. |
| STRENGTH | Excellent strength and stiffness per unit weight. |
| NON-GALLING | Sound and rugged surface, offering a low coefficient of friction and minimum wear, |
REPID HEAT DISSIPATION | Ideal for a broad range of operating temperatures, from 350 degrees Fahrenheit to -30 degrees Fahrenheit. |
| NONMAGNETIC | Good for electrical and computer applications. |
UNIT VOLUME YIELD | Greater amount of finished magnesium material obtained, pound for pound. |
| SALVAGE | Scrap retains a consistently high level of value. |

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.

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.
