Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value exceeding US$5 million, proudly presents our Copper Sealing Strip (Annealed, 0.5mm x 10mm, Soft Temper, 100% Inspection, Roll Length 50m). This premium product is engineered for demanding sealing applications where reliability, flexibility, and long service life are critical. Each strip undergoes rigorous 100% inspection to ensure consistent dimensions and flawless surface quality, making it an ideal choice for OEMs, maintenance teams, and industrial distributors worldwide.
Our copper sealing strip is manufactured from high-purity copper (C1100/C1020) and fully annealed to achieve a soft temper, offering excellent conformability to irregular surfaces. Whether used in gasket fabrication, plumbing, electrical grounding, or automotive sealing, this product provides superior corrosion resistance, thermal conductivity, and ease of installation. With a thickness of 0.5mm and width of 10mm, it strikes the perfect balance between strength and flexibility.
Key Product Features & Benefits
- 100% Annealed Soft Temper: Ensures maximum pliability and reduces installation force, minimizing the risk of cracking or spring-back during assembly.
- High Precision Dimensions: 0.5mm thickness ±0.02mm, 10mm width ±0.1mm – guarantees a perfect fit in standard groove or channel applications.
- Continuous Roll Length 50m: Minimizes joints and waste, offering cost-effective handling for large-scale projects.
- 100% Inspection: Every roll is visually and dimensionally checked; no pinholes, burrs, or surface defects are tolerated.
- Corrosion & Oxidation Resistance: Copper naturally forms a protective patina; suitable for moderate temperature and chemical exposure.
- Excellent Thermal & Electrical Conductivity: Ideal for thermal management and grounding applications.

Frequently Asked Questions
Q1: What is the difference between annealed and half-hard copper strip?
A: Annealed (soft) copper strip is fully softened, making it very pliable and ideal for sealing applications where the strip must conform to irregular surfaces. Half-hard has higher tensile strength but is less flexible. Our 0.5mm x 10mm strip is annealed for optimal sealing performance.
Q2: Can this strip be used for high-temperature applications?
A: Copper has good thermal conductivity and can withstand temperatures up to approximately 200°C in continuous service. For higher temperatures, you may consider alternative materials. Please consult our technical team for specific application advice.
Q3: Is the strip lead-free and RoHS compliant?
A: Yes, our copper strip is made from pure copper (C1100/C1020) and contains no lead or other restricted substances. It meets RoHS requirements. We can provide compliance documentation upon request.
Q4: How is the strip packaged to prevent oxidation?
A: Each roll is wrapped in anti-oxidation plastic film and sealed. For long-term storage, we recommend keeping the strip in a dry, cool environment. If the surface tarnishes slightly, it can be cleaned with a mild acid solution before use.
Q5: What is the minimum order quantity?
A: The standard MOQ is 100 rolls. However, we can provide samples (1-2 rolls) for evaluation at a nominal cost. Please contact our sales team for sample requests.
Q6: Do you offer custom dimensions or temper?
A: Yes, we customize thickness, width, and temper according to customer requirements. Lead time and pricing depend on the specification. Please provide your drawing or requirements for a quotation.
Q7: How long does shipping take to North America?
A: Typical sea freight from our port (Tianjin/Qingdao/Shanghai) to major US West Coast ports takes 18-25 days. Express delivery (DHL/FedEx) is available for sample orders, taking 5-7 days.
Q8: Is 100% inspection guaranteed for every roll?
A: Absolutely. Each roll is visually inspected for surface defects and dimensionally verified using calibrated gauges. We maintain inspection records for traceability.
