Spring washers are often made from carbon steel, stainless steel, or alloy steel. The black finish is applied to protect the washer from rust and wear, extending its lifespan. The black finish is typically achieved through phosphate coating, black oxide, or paint, which provides enhanced corrosion resistance, especially in humid or outdoor environments.
