Copper and Aluminum Washers are flat washers made from two different metals, typically used to distribute loads on fasteners and reduce vibrations. Copper washers are preferred in applications requiring electrical connections and heat transfer due to their high conductivity, corrosion resistance, and flexibility. On the other hand, aluminum washers stand out for their lightweight nature, good corrosion resistance, and cost-effectiveness. Both types of washers are commonly used in the automotive, construction, electrical, and machinery sectors. They provide ideal solutions for ensuring sealing at connection points, preventing wear, and stopping fasteners from loosening. Copper and aluminum washers contribute to long-lasting assemblies by providing reliable connections in various environments and conditions.
