At Hangzhou Target Import & Export Co., Ltd. (HZTG), our high-purity copper disc selections deliver outstanding electrical and thermal conductivity. They are purposefully built for demanding industrial applications. As a premier exporter of non-ferrous metals, we supply both standardized dimensions and bespoke metal blanks. Our cut-to-size products satisfy the strict requirements of power transmission, cookware manufacturing, and high-tech R&D facilities. Backed by a strong factory network across China, our strict quality control ensures every batch meets international standards.
Whether you require conductive components for electrical installations or high-purity variations for vacuum processes, HZTG offers an integrated supply chain solution. We combine raw material procurement with comprehensive post-processing. This approach gives global B2B buyers a reliable partner for high-performance copper products.
In the non-ferrous metal industry, the terms copper disc and copper circle are often used interchangeably. They describe flat, circular metal blanks sheared or punched from sheets and coils. These products boast exceptional physical properties, including electrical conductivity up to 101% IACS and outstanding thermal dissipation. We specialize in delivering precision-cut discs to clients who demand tight dimensional tolerances and burr-free edges.
To facilitate easy procurement, our manufacturing capabilities cover a wide range of optimized parameters. We offer purity levels up to 99.9%, with oxygen-free options reaching 99.95% and above. Thicknesses range from 0.5mm to over 10mm, catering to both thin-foil precision and heavy-duty structural applications. We fully customize diameters, from small micro-components for electronics to large-format blanks for industrial equipment. Available surface finishes include mill, satin-brushed, polished, and custom-coated options.
To ensure high performance in demanding environments, we manufacture our products using premium non-ferrous alloys. We strictly adhere to global manufacturing standards like ASTM B152 to guarantee metallurgical consistency. Below is a detailed overview of our primary copper grades and their properties.
| Copper Alloy Grade | UNS/ASTM Designation | Chemical Composition (Cu %) | Electrical Conductivity (% IACS) | Typical Thickness Range | Primary Characteristics |
|---|---|---|---|---|---|
| C1100 (ETP) | UNS C11000 / ASTM B152 | Min. 99.90% | ≥ 100% | 0.5mm – 12mm+ | Excellent electrical and thermal conductivity. Ideal for general industrial applications. |
| C10200 (OF) | UNS C10200 / ASTM B152 | Min. 99.95% | ≥ 101% | 0.5mm – 10mm | Oxygen-free copper. Superior resistance to hydrogen embrittlement. Perfect for vacuum electronics. |
These premium grades ensure your custom copper disc exhibits precise conductivity and ductility. They provide the structural integrity required for complex mechanical or thermal designs.
At HZTG, we recognize that standard sizes do not fit every manufacturing line. We provide extensive custom processing and fabrication services. This allows buyers to order precision-cut blanks tailored to exact blueprints. Our integrated processing eliminates the need for secondary machining. It ultimately reduces material waste and lowers your final production costs.
Our advanced metal fabrication techniques include:
Mechanical Punching & Stamping: High-efficiency punching for volume orders ensures excellent diameter consistency and cost-efficiency.
Precision Laser & Wire Cutting: Ideal for thicker plates or complex profiles requiring tight tolerances and zero thermal deformation.
Edge Deburring: All processed blanks go through mechanical deburring to provide smooth, safe, and round edges.
Surface Polishing: We provide satin and high-mirror polished finishes, which are vital for visible decorative components.
Bending & Pressing: We offer complete forming services to shape your materials into semi-finished structural parts.
Due to its high electrical conductivity, excellent thermal performance, and superb corrosion resistance, the copper disc serves as a vital component across various sectors.
In electrical and power transmission systems, high-conductivity blanks are widely used as grounding plates, contact backings, and busbar washers. Their high purity level reduces electrical resistance. This helps prevent power loss and overheating in high-voltage equipment. These components remain critical for earthing systems, substation assemblies, and high-power industrial machinery.
The consumer goods sector heavily relies on our materials for thermal efficiency. In premium cookware manufacturing, these discs serve as the core thermal-distribution layer. When clad between stainless steel or aluminum, the copper core ensures rapid, uniform heat distribution. This process eliminates hot spots and prevents warping under high heat.
Scientific research, optical displays, and semiconductor fabrication rely heavily on ultra-high-purity copper discs. Grades like UNS C10200 Oxygen-Free Copper are deployed as physical vapor deposition (PVD) sputtering targets or backing plates. These high-purity targets are essential for depositing thin-film layers onto silicon wafers, glass, or polymer substrates in high-vacuum environments.
Choosing HZTG as your primary B2B partner guarantees a seamless, risk-free sourcing experience. We combine the cost advantages of manufacturing in China with the professional service of an international procurement specialist.
Our wholesale supply advantages stem from a robust factory network. We maintain long-term partnerships with leading Chinese non-ferrous metal plants to ensure reliable material availability and competitive pricing. Quality remains our priority, so every shipment is backed by Mill Test Certificates (MTC). We strictly conform to international regulations, ensuring full REACH and MSDS compliance. Additionally, our professional materials team helps you select the optimal alloy grade and fabrication technique for your specific application.
We support flexible minimum order quantities (MOQ) for both R&D trial batches and full container shipments. Finally, since copper is highly sensitive to moisture, all orders are secured in anti-tarnish packaging inside reinforced wooden crates for safe global shipping.
As a trusted professional copper disc supplier, HZTG is dedicated to keeping your production lines moving. We provide dependable lead times and premium-grade materials tailored to your needs. Contact our engineering team today to request a quote or discuss your custom fabrication requirements.
Q1: What is the difference between a copper disc and a copper circle?
A1: There is no metallurgical or practical difference between the two terms. They are synonyms used interchangeably within the non-ferrous metals industry. "Copper disc" is more common in technical fields like electronics and sputtering targets. "Copper circle" is widely used in metal spinning and cookware manufacturing.
Q2: Which copper grades do you offer for your custom-cut blanks?
A2: We primarily supply high-purity C1100 (Electrolytic Tough Pitch) copper, which is the industry standard for electrical and thermal applications. For high-vacuum, semiconductor, or advanced chemical applications, we provide UNS C10200 (Oxygen-Free) copper. Additional brass and bronze alloys can also be manufactured upon request.
Q3: What custom processing services can you perform?
A3: HZTG offers an array of professional fabrication services. These include mechanical punching, high-precision laser cutting, edge-deburring, and surface polishing. We also provide custom metal bending or pressing based on your specific engineering drawings.
Q4: Do you provide third-party quality certifications for international shipments?
A4: Yes. All our non-ferrous shipments are delivered with official Mill Test Certificates (MTC). These detail the precise chemical composition and physical properties of your materials. We also supply REACH and MSDS compliance certifications to ensure smooth international customs clearance.
Q5: What are your minimum order quantities (MOQ) and packaging standards?
A5: We support flexible MOQs to accommodate R&D trial orders as well as large-scale industrial runs. To prevent oxidation and salt-water damage during maritime transport, all items feature anti-tarnish wrapping. They are then securely packed in robust, export-standard wooden cases.
