Copper Washers – Pressed Components are precision‐fabricated parts produced by cold pressing high-quality copper sheet into washer shapes. These components are engineered to provide reliable load distribution, electrical conductivity, and corrosion resistance in a variety of fastening and sealing applications. Manufactured by Conex Metals using advanced pressing techniques and compound dies, they offer consistent dimensions and superior surface finishes suitable for both industrial and decorative uses. With a strong manufacturing base in Jamnagar, India, we supply Copper Washers to some of the most quality-conscious markets worldwide, ensuring excellence in every piece we produce.
Key Features of Copper Washers
Premium Material:
Made from high-quality copper (commonly pure copper or copper alloys), these washers leverage copper’s excellent electrical and thermal conductivity as well as its natural corrosion resistance.Precision Pressing Process:
The components are produced via high-precision pressing techniques that form the washers from copper sheet metal. This process ensures tight tolerances, uniform thickness, and a smooth, polished surface finish.Versatile Size Range:
Copper washers are available in a wide range of inner and outer diameters and thicknesses to match various fastener standards (such as DIN, BS, or custom requirements), ensuring compatibility in different assembly applications.Enhanced Performance:
The design of these pressed components allows for even load distribution across fasteners and provides a robust, durable sealing surface, minimizing the risk of surface damage and improving joint integrity.
Technical Specifications (Example Values)
| Parameter | Specification (Typical) |
|---|---|
| Material Grade | High-quality copper (e.g., C11000) |
| Thickness Range | Typically 0.2 mm to 3.0 mm (customizable) |
| Outer Diameter Range | Standard sizes from approximately 10 mm to 100+ mm |
| Inner Diameter | Designed to match fastener shank sizes (e.g., M4 to M12) |
| Surface Finish | Polished, with options for additional plating or passivation for enhanced corrosion resistance |
| Tolerance | Generally within ±0.005 mm to ±0.02 mm, depending on size and application |
*Note: Exact dimensions and tolerances can be customized based on specific customer requirements.
