Product Description

What Is 99.99% Pure Copper Wire For Sale？

As a core conductive material for high end precision industrial manufacturing, our company offers 99.99% (4N) ultra pure Copper Wire in stock and custom made to order. With its exceptional purity and superior performance, it is precisely suited for a wide range of demanding industrial applications, providing businesses with efficient, low-consumption, and stable conductive solutions. It is the preferred choice for companies seeking high quality production.

Key Advantages

Guaranteed 99.99% (4N) high purity with exceptional electrical conductivity: With a fixed purity of 99.99% (4N) and strictly controlled impurity levels (total harmful impurities such as iron, lead, and sulfur ≤ 100 ppm), resistivity approaches the theoretical limit, with electrical conductivity reaching 99%–100% IACS, significantly reducing power and signal transmission losses, and meeting the demands of high-precision, low-loss industrial equipment.

Superior physical and chemical properties, easy to process and integrate: Density 8.96 g/cm³, melting point 1083°C, thermal conductivity 395–401 W/m·K, excellent ductility, can be drawn into various specifications ranging from 0.002 mm to 8.0 mm, tensile strength 200–380 MPa, elongation 15%–40%, fatigue-resistant and fracture-resistant, with a bright, oxidation-free surface and excellent weldability, facilitating equipment integration and subsequent processing.

Stable and durable, suitable for diverse operating conditions: Utilizing oxygen free refining technology, with oxygen content ≤10 ppm, it eliminates oxide inclusions. It does not oxidize or degrade in performance over long-term use, offers excellent corrosion resistance, and operates stably within a temperature range of -40°C to 120°C, making it suitable for various industrial environments including atmospheric, aqueous, and high-vacuum conditions.

Precision manufacturing with rigorous quality control: The entire production process strictly adheres to international standards such as ASTM B170, B152, and IEC 60228. Every batch undergoes purity testing, full surface inspection, electrical conductivity testing, and tensile strength verification to ensure that every meter of copper wire meets high-quality standards. Samples are available for spot inspection at any time.

Stock Availability and Flexible Customization: Ample stock of 99.99% (4N) purity is available. We offer customization for wire diameter (0.002 mm–8.0 mm), length, form (solid/stranded/multi-strand rope/straight bar/coiled wire), and surface treatment (bare copper/tin-plated/silver-plated/ nickel-plated/enameled), and annealing conditions. Packaging can be customized with plastic, wooden, or metal spools to meet diverse industrial and shipping requirements, with fast delivery.
