Why Choose Nickel Alloys?
Nickel is known for its exceptional properties that outperform many conventional steels and stainless steels, including:
– Superior Corrosion Resistance: Excellent performance in caustic, acidic, and saltwater environments.
– High-Temperature Strength: Retains mechanical properties under elevated temperatures.
– Dimensional Stability: Low thermal expansion ensures stability across temperature extremes.
– Fabrication Versatility: Readily formed, welded, and machined to tight tolerances.
These characteristics make nickel alloys ideal for critical components exposed to harsh operating conditions.

- Nickel 201 (UNS N02201): Similar to Nickel 200 but with lower carbon for improved thermal stability.
- Monel® 400 (UNS N04400): Nickel-copper alloy noted for superior resistance to seawater and corrosive media.
- Inconel® 600/601 (UNS N06600 / N06601): Nickel-chromium alloys with outstanding oxidation resistance and high-temperature strength.
- Inconel® 625 (UNS N06625): High-strength, corrosion-resistant alloy for extreme service environments.
- Incoloy® 825 (UNS N08825): Alloyed for resistance to reducing and oxidizing acids.
