Alloy 20 Foil is a nickel-iron-chromium alloy comprising 20% chromium, 3.0% molybdenum, 4.0% copper and balanced iron with small amounts of other elements. It provides outstanding corrosion resistance in various types of acidic media and excellent general corrosion in alkaline solutions. Alloy 20 Foil is suitable for applications in pharmaceutical processing, food production and chemical equipment where strength, superior corrosion resistance and long-term reliability are required.

Alloy 20 Foil is an alloy of nickel, chromium and molybdenum. It has excellent resistance to hot sulphuric and hydrochloric acids and stress-corrosion cracking. The alloy is known for its superior corrosion resistance in various environments. It can be used in extreme temperatures ranging from -352°F (-210°C) to 1,000°F (538°C). Due to its strength and corrosion resistance properties, it has found many general engineering applications in chemical processing industries. Some other uses include heat exchanger components, tank systems components, etc.
