Request QuoteWhat are Nickel 200 Washers?
Nickel 200 washers are flat, circular components made from commercially pure wrought nickel, known for its high chemical purity (minimum 99% nickel). These washers are widely used in applications that demand high thermal stability & long-lasting mechanical performance.
Designed for industrial-grade reliability, Nickel 200 washers act as a supportive barrier under nuts, bolts, or fasteners, distributing load evenly and preventing surface damage. Nickel 200, designated under UNS N02200, is a solid-solution strengthened nickel alloy with good ductility and electrical conductivity. It performs well across a broad temperature range and retains strength without undergoing hardening due to heat treatment. It is highly resistant to alkaline solutions, neutral salts, dry gases like hydrogen and fluorine & maintains stability even in reducing chemical environments.

Size Chart for Nickel 200 Washers
Nickel 200 washers are manufactured in a variety of standard and custom sizes to meet diverse industrial requirements. The size of a washer typically includes its inner diameter (ID), outer diameter (OD), and thickness, which together determine its fit and load-bearing capacity in a bolted joint.
- Inner Diameter (ID): Ranges from M3 to M64 (or 1/8" to 2.5"), matching standard bolt sizes.
- Outer Diameter (OD): Generally 1.5 to 3 times the inner diameter, depending on type (flat, lock, or sealing).
- Thickness: Varies based on design requirements, typically between 0.5 mm to 6 mm.
Custom sizes can also be produced to meet non-standard dimensions or application-specific requirements, including oversized or under-sized OD or ID for special fits.
