Formula: Mg 96/Al 3/Zn 1
Form: Foil (Light Tight)
Material: Magnesium AZ31
Commodity: Alloys
Light Tight:
Light Tight
AZ31 foil from Goodfellow is an aluminum alloy foil product designed for light blocking applications. With a magnesium content of 3%, AZ31 foil combines moderate strength with excellent corrosion resistance while remaining highly reflective across visible and infrared wavelengths. The material's opacity to light makes it useful for radiation shielding in optical devices. AZ31's ductility also allows it to be formed into complex shapes without cracking, enabling applications like protective housings and packaging for photosensitive components. As part of Goodfellow's extensive foil inventory, AZ31 delivers versatile light blocking performance.
