Nickel Foil is employed in the diverse corrosion conditions such as neutral, acidic and alkaline salts, sulphuric acid and phosphoric acid. The metal provides sufficient resistance to the strong and rigorous salts such as phosphorous trichloride, phosphorous oxychloride and benzoyl chloride.
Nickel exhibits face centered cubic lattice structure that offers improved formability and strength. The machining of strip is performed with the large paced cutting equipments at the lower speed.
