3.Copper naturally resists rust, making these washers ideal for outdoor use or damp environments.

4.Copper washers can handle higher temperatures than steel washers. They are perfect for car engines, exhaust systems, and other hot areas.

5.Made from high-quality copper, these washers are strong and long-lasting. Each one is carefully made with a smooth surface and rounded edges.
