Applications

Applications requiring a flat surface or high dimensional stability benfit from the use of TOOLING PLATE. Typical uses include vibration test equipment, jigs, fixtures, optical benches, and inspection gauges.

TOOLING PLATE is non-magnetic and has high electrical and thermal conductivity making it a good choice for many requirements in the electronics and computer industries.

AZ31 TOOLING PLATE is specially made 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.

Durability

The high strength-to-weight ratio of magnesium minimizes damage to tools during machining, therefore achieving greater tool life. Original tolerances are unaffected long after use. TOOLING PLATE is non-galling, with a low coefficient of friction, reducing wear over the lifetime of the tool. Alkaline cleaners will not affect the tolerances of toolplate fixtures, allowing cleaning without danger of damaging sensitive surfaces. As a rolled product, TOOLING PLATE is free of internal voids.

Heat Treatment

TOOLING PLATE is delivered in the thermally stabilized condition. User thermal processing is not required.

TOOLING PLATE has an exceptional capacity for absorbing vibrational energy and dissapating it in the form of heat energy. This unique characteristic can be effectively utilized by designers for the attenuation of vibration and noise. A comparison with other engineering materials rates TOOLING PLATE very well in what can be a critical design factor.

Weldability

Gas sheild metal arc and most other welding processes can be used successfully to produce welds with 95% of the parent plate strength. Generally, weldments will require stress relief for dimensional stability, however, each applications should be reviewed individually.

Machining

TOOLING PLATE, like all magnesium alloy 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.

TOOLING PLATE has excellent dimensional stability during and after machining, even when machined extensively. This, coupled with the superior surface finish readily obtained in machining, makes TOOLING PLATE, a strong candidate for dimension critical items.
