Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision metal components. Our Flat Copper Sealing Strip 0.8mm Thick, 15mm Wide is engineered to deliver reliable sealing performance in demanding industrial applications. With a tensile strength of 200 MPa and a comprehensive Mill Test Report provided with each shipment, this product ensures consistent quality and traceability. Whether you need gaskets for hydraulic systems, electrical insulation, or custom sealing solutions, our copper strip offers the perfect balance of flexibility and durability.
The strip is manufactured from high-purity copper, ensuring excellent thermal and electrical conductivity. Its flat profile and precise dimensions (0.8mm x 15mm) make it ideal for creating custom gaskets, washers, and seals in machinery, automotive, and plumbing applications. The 200 MPa tensile strength guarantees that the strip can withstand moderate mechanical stress without deformation, while the mill finish provides a clean, oxide-free surface ready for immediate use.
Key Features & Benefits:
- High Precision Dimensions: Thickness tolerance of ±0.03mm and width tolerance of ±0.1mm ensure consistent performance in automated assembly lines.
- Excellent Sealing Capability: The soft copper material conforms to irregular surfaces, creating a tight, leak-proof seal against gases, liquids, and dust.
- Corrosion Resistance: Copper naturally resists oxidation and corrosion in most environments, extending service life.
- Thermal Conductivity: Ideal for heat dissipation applications such as heat exchanger gaskets.
- Mill Test Report (MTR): Each batch comes with a certified MTR documenting chemical composition, tensile strength, and dimensional accuracy, providing full traceability for quality audits.
- Customizable Length: Available in coils or pre-cut strips to meet your specific production requirements.
