What are nickel washers?

Nickel washers are precision gaskets made from nickel alloys (e.g., Nickel 200, Inconel 625, Monel 400, etc.) Nickel alloy washers are renowned for their superior corrosion resistance, maintaining excellent performance even in highly corrosive environments such as seawater and chemical processing plants. Their durability ensures long-term reliable performance, reducing the need for frequent replacement. In addition, their excellent weldability enables seamless integration into complex assemblies, making them an indispensable material in critical applications ranging from offshore platforms to chemical reactors.
