Hakan Nickel Alloys, based in Istanbul, Turkey, makes Monel Washers, which are small, strong metal discs used with bolts, screws, and nuts to hold parts tightly together. These washers are carefully made to be smooth, durable, and resistant to rust and corrosion. Monel Washers are perfect for industries where connections must stay secure under tough conditions, like chemical plants, marine systems, and industrial machinery. At Hakan Nickel Alloys, every washer is tested for quality, giving engineers and builders reliable materials for safe and long-lasting assemblies in machines, equipment, and piping systems.
Monel Washers are made mostly of Monel alloy, which is a combination of nickel and copper. This makes them very strong, tough, and resistant to rust, corrosion, and chemicals. They can handle high pressure, heat, and repeated use without cracking, bending, or wearing out. Lightweight yet durable, Monel Washers maintain their shape and strength over time. They are ideal for chemical, marine, power, and industrial applications where safe, strong, and long-lasting fasteners are required.
