Products Description

Bare copper wire that has been drawn softly is created by extracting copper from pure copper rods. The wire is made up of a single material and is entirely composed of copper metal on the inside and outside. It has a visually appealing appearance with a bright and clean finish that is smooth to the touch, and the hue is that of pure copper. Physical characteristics of the bare copper wire encompass its softness and exceptional electrical conductivity.

Copper is highly valued for its properties of conductivity and strength, especially in the field of electrical engineering. It finds usage in a wide range of applications such as power cables, connectors, transformers, switches, and busbars. Additionally, in the manufacturing of electric motors, copper alloys with high conductance and strength are commonly employed.

Product Features

This material boasts excellent electrical conductivity, thermal conductivity, and corrosion resistance, in addition to processing versatility which allows for welding and brazing. However, it is not advisable to utilize it in high-temperature reducing atmospheres or during processing such as annealing or welding.

Application field

Copper wire in its bare form is extensively transformed and utilized in various cable applications, encompassing cables for general use, high voltage transmission, telecommunications, underwater applications, automotive circuitry, solar power systems, electronic devices, and electromechanical systems.

Physical properties

The table provided lists the mechanical and physical properties of bare round wires that are commonly used. Copper wires that are not coated have several advantages, such as being soft to the touch, having a high level of electrical conductivity, and exhibiting excellent heat transfer characteristics.

QA&QC Quality Assurance and Quality Control

According to the guidelines of GB/T 3953 "Electrical Round Copper Wire" and GB/T 4909 "Test Methods for Bare Wires," the production and inspection of bare copper wires must strictly adhere to certain standards. These standards ensure that the wires are manufactured and evaluated in a meticulous manner. Conforming to the regulations set forth by GB/T 3953 and GB/T 4909 guarantees that the production process consistently produces high-quality bare copper wires. Moreover, conducting thorough inspections based on these guidelines allows for the assessment of various characteristics and properties of the wires, ensuring their reliability and safety. By following the recommended procedures and techniques outlined in these standards, manufacturers can assure the consistent production of bare copper wires that meet the industry's requirements and expectations.

Packaging, storage, handling and shipping

To guarantee that the bare copper wire meets both customer and industry requirements, it must undergo proper packaging, storage, handling, and transportation procedures. This is done to prevent moisture and damage from affecting the quality of the end product. Strict adherence to these guidelines is necessary to maintain the integrity of the copper wire as it passes through various stages in the production process. Only then can the wire be considered ready for use in a wide range of applications.

Q.Can bare copper wire be used for outdoor applications?

Bare copper wire can be used for outdoor applications, but it is important to ensure that it is properly grounded and protected from moisture, corrosion, and other environmental factors.

Q. How is bare copper wire priced?

The price of bare copper wire depends on several factors, including the gauge, length, and quality of the wire. It can be purchased by the spool or by the foot from hardware stores, electrical supply stores, and online retailers.
