Choose these washers for their adherence to strict military standards for material and construction.
Cadmium- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.
Aluminum washers are lightweight and have good corrosion resistance. 1100 aluminum washers are made of an aluminum that is commercially pure, so they have excellent corrosion resistance and electrical conductivity. However, they’re not as strong as 2024 aluminum. They are commonly used in the chemical and food processing industry. 2024 aluminum washers are easy to machine. They are stronger and resist wear better than 1100 aluminum. They are commonly used in the aircraft industry and in veterinary and orthopedic equipment.

USS washers generally have a larger ID and OD than SAE washers.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic. Black-oxide washers have a matte-black finish.
Zinc-plated steel washers are corrosion resistant in wet environments.
Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc-plated washers.
Black ultra-corrosion-resistant coated steel washers resist chemicals and withstand 1,000 hours of salt spray.

Also known as spherical washers, these consist of a male and female washer that, when nested, swivel slightly to compensate for tolerance variations and uneven surfaces. They're good for die and fixturing applications.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Black-oxide steel washers are mildly corrosion resistant in dry environments.
