Introduction
Super alloy Ametek 899E is a lower carbon version of commercially pure (99%) nickel. The material does contain other elements but in very small quantities adding to be than 1%.
Ametek 899E (annealed high purity nickel strip) offers the lowest electrical resistivity among pure nickel strip. It provides excellent solderability and formability.
