Product Overview

What are Titanium Grade 1 Washers?

Titanium Grade 1 washers are precision flat or shaped fastener components manufactured from commercially pure titanium (UNS R50250) conforming to ASTM B265 and ASTM F67. As the softest and most ductile of all titanium grades, Grade 1 offers exceptional corrosion resistance in oxidizing and mildly reducing environments, making these washers ideal for critical bolted joints where both chemical resistance and low weight are required.

With a density of just 4.51 g/cm³ and outstanding resistance to chlorides, seawater, and a wide range of acids, Titanium Grade 1 washers are specified for aerospace, chemical processing, desalination, and medical device assemblies. All washers are supplied with full traceability and EN 10204 3.1 certification.

Material Chemistry

Titanium Grade 1 Chemical Composition

Titanium Grade 1 Washers are manufactured from commercially pure or alloyed titanium with elemental limits strictly controlled per ASTM and AMS specifications. Oxygen and nitrogen contents govern strength and ductility in CP grades; aluminium and vanadium additions in Ti-6Al-4V (Grade 5) deliver 896 MPa tensile strength at 4.43 g/cm³ density.

? All heats spectrographically verified. Full PMI and traceability provided with every batch.

Why Titanium Grade 1 Alloy Composition Matters for Washers

High Purity Titanium — Corrosion Resistance
The extremely low content of interstitial elements (O, N, C, H) in Grade 1 titanium ensures maximum ductility and resistance to stress corrosion cracking, making these washers ideal for use in aggressive chemical and marine environments.
Low Iron Content — Prevents Galvanic Corrosion
With iron limited to 0.20%, Titanium Grade 1 washers minimize galvanic corrosion when used with other titanium or noble metal fasteners, ensuring long-term joint integrity in seawater and chloride-rich atmospheres.
Biocompatibility
Grade 1 titanium is non-toxic and fully biocompatible, making these washers suitable for medical implants, surgical devices, and food processing equipment.
