Zinc Foil

Formula: Zn

Form: Foil/Film/Sheet

Material: Zinc

CAS Number: 7440-66-6

Commodity: Metals

Zinc Foils from Goodfellow are high purity zinc metal foils in a variety of sizes and thicknesses. Zinc has a low melting point, high ductility, malleability and a blue-silvery appearance. These foils are useful for research and development applications, as well as industrial applications like corrosion protection coatings for steel. With our range offering 242 variations, there are options suitable for prototyping, testing, and small to medium scale production.
