Formula: Al97/Mg 3
Form: Coil
Material: Aluminum/Magnesium Alloy
Commodity: Alloys
Available in 90 variations, our range of Aluminum/Magnesium Alloy Coils (Al97/Mg 3) combine the lightweight properties of aluminum with the strength of magnesium. One of their many benefits is the ability to be formed into a variety of shapes while maintaining strength and corrosion resistance. Their applications include insulation, packaging, and shielding across aviation, automotive and electronics industries, where weight savings and performance are critical. Our wide selection of alloy compositions and tempers provides you with the flexibility to choose the optimal balance of formability, strength and conductivity.
