Aluminium Alloy 19000 Foil is an aluminium alloy foil composed of 95.8-98.3% aluminium, 0.2-0.8% copper and small amounts of magnesium, manganese, zinc and silicon. This makes it very lightweight yet durable in harsh environments while still being easily formable into complex shapes with excellent aerodynamics, which makes it suitable for aircraft and automotive use.
Aluminium Alloy 19000 Foil is a popular industrial alloy due to its lightweight, good strength-to-weight ratio, corrosion resistance and strong mechanical properties. It has excellent electrical and thermal conductivity, making it ideal for transformer windings and busbar applications. Its chemical composition makes it resistant to many acids and bases while still being able to be formed easily into desired shapes, which adds to its versatility.
