Magnesium Plate az91 magnesium plate az91D

Magnesium sheet az91/ Mgnesium plate az31/ magnesium alloy plate

AZ91D 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).

APPLICATIONS

Sheet and plate in AZ91D 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 AZ91D.

AZ91D 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 AZ91D 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.

 Features of Standard Mg Plate

1. Magnesium is light metal, it’s ion exists widely in soil and water, and harmless to human body or environment.
2. The Magnesium plates was etched very fast, normally within 3 minutes in the new chemical.
3. Magnesium photoengraving plate is lightest between Brass and Zinc plate. Therefor the magnesium engraving plate is better to be pasted and stamped.
4. No deformation happen during hot stamping process. Fast temperature rising, the stmping rate is more than 120000 times.
5. Magnesium engraving plate is easier to be etched with a highest speed between Brass and Zinc engraving plate. Normally magnesium engraving plate is to be etched in 1 mm deepth within 7 seconds.
6. The surface hardness of the magnesium plates is very close to the cooper.
7. The magnesium plate after rolling with 3000 tons cold rolling mill and also 2500tons hot rolling mill, then do the tempering treatment, our plates with uniform thickness, the tolerance of thickness is near zero, the plates is no anisotropy, eliminate the internal stress of the plates.
