Frequently Asked Questions (FAQs)

1. What metal is used to make washers?

Washers are made from a variety of materials, the most popular of which are galvanized carbon steel and stainless steel. Carbon steel is stronger than stainless steel, but stainless steel will not rust or corrode like carbon steel can. Other metal washers include zinc, copper, brass and iron.

2. What material is used to make washers?

Washers can be fabricated from a variety of materials including, but not limited to: Steel – Carbon steel, spring steel, A2 (304) stainless steel, and A4 (316/316L) stainless steel. Non-ferrous metal – Copper, brass, aluminium, titanium, iron, bronze, and zinc. Alloy – Silicon bronze, Inconel, Monel, and Hastelloy.

3. What are stainless steel washers used for?

Steel washers are flat disks on steel or stainless steel with a hole punched through the middle. They are used to distribute the load over a larger area and protect surfaces during the installation of screws and bolts.

4. Are stainless steel washers rust proof?

As an added bonus, silicone bronze is far more cost-effective than other alloys that provide the same characteristics. Stainless steel is well-known as a corrosion-resistant metal, one that is widely used because of its bright finish and its compelling weight-to-strength ratio.
