Industrial-grade copper wire is fundamental to modern electrical engineering and global manufacturing. It serves as the critical backbone for power distribution, custom electronics, and alloy fabrication. As a specialized non-ferrous metal supplier and exporter, Hangzhou Target Import & Export Co., Ltd. delivers an extensive material range. We provide high-conductivity uninsulated copper, brass, and specialty bronze wires designed for rigorous B2B applications. Our team integrates metallurgy expertise with global export standards. This ensures clients receive the exact material grades, tempers, and spooling layouts required for high-precision projects.
By coordinating with leading Chinese partner factories, we bridge the gap between heavy industrial production and specialized design. Our engineering team helps procurement managers choose the ideal materials. We balance electrical conductivity, tensile strength, and corrosion resistance to optimize performance. Whether your project demands standard bare copper wire or specialized bronze configurations, we support your operations. You can rely on us for consistent material supply, custom dimensional capabilities, and expert supply chain management.
Selecting the proper alloy composition is critical for achieving optimal mechanical and electrical performance. Our comprehensive selection of copper wire is engineered to meet diverse technical requirements. We support applications across the automotive, marine, electrical, and structural industries. By offering specialized chemical profiles, we enable engineering teams to source materials tailored to precise conductivity and resistance thresholds.
To help guide your selection, the table below outlines the primary copper, brass, and bronze options available through our procurement networks:
| Alloy Grade / Type | Key Chemical & Physical Properties | Primary Industrial Applications |
|---|---|---|
| C11000 ETP Copper | 99.90% purity minimum, outstanding 101% IACS electrical conductivity, high thermal transfer. | Electrical distribution systems, grounding wires, busbar connections, and electrical components. |
| Oxygen-Free Copper (OFE/OFHC) | High-purity, low-oxygen composition preventing hydrogen embrittlement, excellent vacuum integrity. | High-vacuum electronics, advanced audio systems, semiconductor packaging, and scientific instruments. |
| Custom Brass Options | Copper-zinc alloy combining high tensile strength, exceptional wear resistance, and bright finishes. | Decorative architecture, hardware manufacturing, precision instrumentation, and EDM wire-cutting. |
| Phosphor Bronze | Copper alloyed with tin and phosphorus, delivering superb fatigue resistance, elasticity, and corrosion resistance. | Heavy-duty springs, electrical connectors, marine-grade hardware, and wear-resistant fasteners. |
Understanding the structural differences between solid and stranded bare copper wire configurations is essential. It helps optimize system durability, routing, and installation ease. Solid wire consists of a single, thick, continuous metal strand. This structural rigidity provides high physical strength and lowers surface oxidation hazards. It is incredibly durable for long-term outdoor installations. Customers commonly deploy it as ground wire, in power transmission lines, and in static structural grounding systems.
In contrast, stranded bare copper wire features several fine strands interwoven into a unified bundle. This configuration dramatically improves flexibility and mechanical fatigue resistance under repetitive stress. Stranded wire is the preferred choice for complex routing, tight bend radii, or dynamic movement. Common applications include industrial jumper cables, motor windings, and vehicle wiring systems. Our technical specialists are available to help your team compare load requirements and movement profiles. We will ensure you select the safest, most efficient wire construction.
The mechanical temper of uninsulated wire drastically changes how the material behaves during handling and deployment. For applications requiring flexibility and easy manual manipulation, soft annealed copper wire is the industry standard. A controlled thermal annealing process relieves internal crystal stresses. This results in a highly ductile wire that can be bent, coiled, and routed without fracturing. Annealed wire is perfect for electromagnet coils, transformer windings, and intricate grounding configurations.
Some applications require strong physical support and resistance to sagging. In these cases, hard-drawn copper wire is the necessary choice. Retaining its cold-drawn crystal structure, this material provides high tensile strength and minimal elongation under load. This rigidity makes it ideal for long-span overhead distribution cables and structural reinforcement. The wire easily supports its own weight without stretching out of tolerance over years of environmental exposure.
