Copper Washers

Product Description

A copper washer is a flat, circular component made from copper, typically used in mechanical and plumbing applications. Its primary purpose is to act as a seal or spacer between two mating surfaces. Copper washers are valued for their properties, including:

Characteristics:

1. Material: Copper is a soft, malleable metal with excellent thermal and electrical conductivity.
2. Shape: Usually circular with a hole in the center (doughnut-shaped) to accommodate a bolt, screw, or pipe fitting.
3. Sizes: Available in a range of diameters and thicknesses to suit various applications.
4. Surface: Often smooth to ensure effective sealing.

Advantages:

1. Corrosion Resistance: Copper resists oxidation and degradation, making it suitable for harsh environments.
2. Ductility: Its flexibility allows the washer to conform to irregularities in mating surfaces, enhancing its sealing properties.
3. Thermal Conductivity: It can withstand and dissipate heat efficiently.
4. Reusable: Copper washers can often be annealed (softened through heating) to restore their sealing capability.

Applications:

1. Sealing: Commonly used in automotive, hydraulic, and plumbing systems to prevent fluid or gas leaks.
2. Load Distribution: Spreads the force of a fastener over a larger surface area to prevent damage to softer materials.
3. Electrical Connections: Used in electrical systems due to copper's excellent conductivity.

Common Uses:

• Oil drain plugs in engines.
• Hydraulic fittings and fuel systems.
• Sealing in refrigeration and air conditioning systems.
• Fastening and sealing in electrical equipment.

Copper washers are a reliable choice in scenarios requiring durability, sealing efficiency, and resistance to environmental factors.
