600 NICKEL BAR
600 NICKEL BAR
Nickel Alloy 600 bar, rod, and wire is a nickel-chromium alloy that provides excellent resistance to oxidation at high temperatures. It is also commonly used as a corrosion-resistant alloy due to its resistance to a wide range of acids and alkalis.

Corrosion Resistance
The composition of Nickel 600 provides corrosion resistance in a wide range of corrosive environments. The addition of chromium provides superior corrosion resistance in acidic environments, compared to a pure nickel, while allowing the material to maintain corrosion resistance in a reducing state and exhibit superior corrosion resistance to alkaline solutions. Nickel Alloy 600 is also highly resistance to stress-corrosion cracking.
