Washers: Materials, Types, Applications and Other Considerations

Alloy washers are circular metal discs with a central hole, designed to be used with screws or bolts for secure fastening.

Typically made from high-quality alloy, often a mix of nickel and other metals like iron, these washers offer exceptional strength and durability. They are highly resistant to corrosion and have excellent wear resistance, making them superior to other washer types.

Washers play a crucial role in various machines and components, enhancing strength, durability, and protection against corrosion.

Common materials of washers include stainless steels and nickel alloys, ensuring compatibility with different applications.

Whatever size at whatever tight tolerance of custom made washers you demand, SEATHER here is sure to have it!
