The Essence of C11000: 99.9% High Purity Unlocks the Upper Limit of High-End Performance
As a core grade of high-purity electrolytic copper (ETP), C11000 features a copper content of ≥99.9% with impurity levels ≤0.1%, it is the material of choice for high-conductivity and high-thermal-conductivity copper in high-end manufacturing. Its inherent material properties are ideally suited to the demanding requirements of high-end applications, and this is the core competitive advantage that distinguishes our products from ordinary copper rods. Compared to copper alloys such as C21000 and low-purity copper rods, it offers irreplaceable performance advantages:
1. Ultimate Purity: The Foundation of Performance
Selected from 99.9% high-purity electrolytic copper raw materials, the product undergoes multiple vacuum smelting and purification processes to thoroughly remove harmful impurities such as iron, lead, and oxygen. This ensures the copper rod has a dense microstructure free of defects such as porosity, looseness, or sand holes, guaranteeing the stability and consistency of product performance from the source. This exceptional purity not only optimizes the copper rods’ electrical and thermal conductivity but also effectively prevents issues such as processing cracks and performance degradation caused by impurities, meeting the core requirements of high-end precision manufacturing.
2. Exceptional Electrical and Thermal Conductivity, Suitable for High-End Energy Transmission Applications
C11000 material boasts an electrical conductivity of ≥98% IACS and a thermal conductivity of 401 W/(m·K), second only to silver and more than 1.2 times that of ordinary copper alloys. It enables highly efficient energy transmission and heat dissipation with negligible resistive losses. Whether used in conductive components of high-end electrical equipment or as core components in precision heat dissipation systems, its superior electrical and thermal conductivity enhances the operational efficiency and service life of end products, making it particularly suitable for high-voltage, high-frequency electrical equipment and precision heat dissipation applications.
3. Excellent Machinability, Suitable for Precision Forming Requirements
C11000 copper rod possesses exceptional cold and hot working properties. In the cold-worked state, it supports complex processes such as deep drawing, stretching, bending, and turning. During hot working within the 750–950°C range, its performance remains stable, with minimal risk of cracking, chipping, or deformation during processing, allowing for precision forming without complex pretreatment. Additionally, its excellent weldability (requiring avoidance of high-temperature reducing atmospheres to prevent hydrogen embrittlement) makes it suitable for precision welding processes in high-end manufacturing, ensuring smooth and robust joints that meet the processing requirements of precision components.
4. Reliable corrosion resistance, suitable for long-term use in diverse environments
In atmospheric conditions, fresh water, and various non-oxidizing acid, alkali, and salt solutions, C11000 copper rods naturally form a dense protective oxide layer, providing excellent corrosion resistance. They are resistant to rust and aging, with a service life of up to 50 years. Furthermore, their non-magnetic properties make them suitable for high-end applications—such as electronics and aerospace—that require freedom from magnetic interference, thereby further expanding the product’s application scope.
Standard-Level Quality Control: Full Traceability from Raw Materials to Finished Products
Based on the stringent requirements of the ASTM B187 standard, we have established a quality control system that integrates standards throughout the entire process. This ensures full traceability across the entire supply chain—from raw material selection to the shipment of finished products—guaranteeing that every C11000 copper bar meets the quality standards required for high-end manufacturing:
1. Raw Material Traceability Control: We select 99.9% high-purity electrolytic copper material that meet the ASTM B187 standard. Every batch of raw materials comes with complete material certificates and test reports. We use spectrometers to precisely test chemical composition and purity, rejecting any non-conforming materials to ensure raw material quality meets standards and establish a solid foundation for quality from the source.
2. Standardized Process Control: We employ advanced processes such as automated vacuum smelting, precision drawing, and isothermal annealing, strictly adhering to ASTM B187 standards throughout the entire process. Key parameters—including smelting temperature, processing speed, and dimensional accuracy—are monitored in real time to ensure every step meets standard specifications and to prevent quality deviations caused by human error.
3. Multi-dimensional Finished Product Testing: Every batch of finished products undergoes seven standard inspections: chemical composition testing, dimensional accuracy testing, electrical and thermal conductivity testing, mechanical property testing (tensile strength ≥235 MPa, elongation ≥10%), surface quality testing, non-destructive testing, and compliance testing. All inspection data is recorded and archived to ensure products meet the ASTM B187 standard and C11000 material requirements. Products that fail inspection are strictly prohibited from leaving the factory.
4. Compliance and Certification Assurance: Our products are certified to the ASTM B187 standard, ISO 9001 Quality Management System, and RoHS environmental standards. We provide complete standard test reports, material certificates, and compliance certificates to help enterprises quickly pass high-end supply chain access audits and reduce compliance costs.
