Copper washers are precision-engineered components made from high-purity copper, designed to provide both load distribution and sealing in mechanical assemblies. Their soft, malleable nature allows them to deform under pressure, creating a tight, leak-proof seal while protecting the fastener and mating surface from damage. Copper's excellent thermal and electrical conductivity, corrosion resistance, and resistance to galling make these washers ideal for high-pressure, hydraulic, plumbing, and automotive applications where reliability and durability are critical.
Manufactured to precise standards such as DIN 125A, copper washers are fully compatible with a wide range of fasteners. The standard ensures that the outside diameter is typically twice the inside diameter, providing consistent performance across applications.
Copper washers are ideal for sealing and high-pressure applications. Due to their softness and corrosion resistance, they can deform slightly under pressure to create a tight seal between the fixing and mating surface. This makes them perfect for applications where leak prevention is critical.
Common uses include:
Copper washers combine strength, flexibility, and corrosion resistance, making them a reliable choice for both industrial and high-performance applications. Their ability to conform to surfaces ensures a secure, leak-proof seal every time.
Compared to steel or aluminium washers, copper washers are softer and more malleable, providing superior sealing performance in dynamic or high-pressure environments. They are especially effective where corrosion resistance and long-term reliability are required.
