Copper Wire Rods
Aulone uses the most technically advanced SCR continuous casting and rolling rod system and up-ward casting process system to produce electrolytic tough pitch (ETP) copper rod and oxygen-free copper rod (OFC)．As a big and responsible copper rod supplier, our copper rods use the raw material—-copper cathode (99.99% purity) which should registered on LME & SME. We have the most competitive copper & brass wire products in the market.
Introduction to Copper Wire Rods
Composition and Manufacturing: Copper wire rods are produced from high-purity copper, typically exceeding 99.9% purity. This purity level ensures excellent electrical conductivity, making copper ideal for various industrial applications. The manufacturing process involves several key steps:
Smelting: Copper ore undergoes smelting to extract copper concentrate, which is then refined into cathodes with high purity levels suitable for further processing.
Continuous Casting: The refined copper cathodes are melted in a furnace and then cast into continuous billets or bars through a continuous casting process. This step ensures uniformity and quality in the material.
Rolling: The cast billets are hot rolled into wire rods of various diameters. This rolling process helps achieve the desired mechanical properties and dimensions required for specific applications.
Types of Copper Wire Rods
Oxygen-Free Copper (OFC):
- Description: Oxygen-free copper wire rods have extremely low oxygen content (<0.001%), enhancing their electrical conductivity and making them suitable for high-performance applications.
- Applications: Used in high-end audio equipment, aerospace components, and sensitive electronic devices where minimal signal loss is critical.
Electrolytic Tough Pitch Copper (ETP):
- Description: ETP copper wire rods have a small but controlled amount of oxygen (0.02-0.04%) and are known for their excellent balance of electrical conductivity and mechanical strength.
- Applications: Widely used in electrical wiring, power distribution systems, and telecommunications due to their reliability and cost-effectiveness.
Diameter and Coating Varieties:
- Copper wire rods come in various diameters ranging typically from 8 mm to 20 mm, with finer sizes used in delicate applications such as electronics.
- Some variants may feature coatings or platings to enhance corrosion resistance or improve solderability, depending on the specific application requirements.
Applications of Copper Wire Rods
Electrical and Electronics:
- Cable and Wire Manufacturing: Primary use in the production of electrical cables and wires due to their excellent conductivity.
- Printed Circuit Boards (PCBs): Used as conductive traces in PCBs for consumer electronics and industrial applications.
Construction and Infrastructure:
- Grounding Systems: Essential for grounding systems in buildings and infrastructure projects.
- Architectural Uses: Used in architectural applications for structural integrity and conductivity.
Telecommunications:
- Communication Cables: Integral in the manufacturing of communication cables for reliable data transmission and telecommunications infrastructure.
Automotive and Industrial Equipment:
- Motors and Generators: Used in the production of motors, generators, and industrial machinery where electrical conductivity and durability are critical.
Environmental and Sustainability Aspects
Copper wire rods are highly recyclable, with recycling rates typically exceeding 90%. Recycling not only conserves natural resources but also reduces energy consumption and greenhouse gas emissions associated with primary production.

What is Bare Copper Wire Used for
8mm stranded wire is a type of electrical conductor made of copper that does not have any insulation or coating. It is typically a single strand of pure copper wire that is used in a wide range of electrical applications. Copper is a highly conductive material, making bare copper wire an excellent choice for electrical wiring and grounding applications.
8mm copper wire is widely used in electrical and electronics applications where conductivity and corrosion resistance are important.
Grounding: 8mm electrical wire is commonly used for grounding electrical systems and equipment. It provides a low-impedance path for fault current to flow and protects against electrical shocks and damage.
Electrical wiring: Bare copper wire can be used as an electrical conductor in wiring applications where insulation is not required. This is often the case in high-temperature applications, such as in ovens, or in industrial environments where the wire is protected by conduit or other means.
