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. |
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.
