Feature	Description	Importance
Conductivity	Ability to conduct electrical current. Measured in Siemens per meter (S/m).	Crucial for power transmission and electronic applications.
Tensile Strength	Resistance to breaking under tension. Measured in megapascals (MPa).	Determines the wire’s ability to withstand stress and strain.
Ductility	Ability to be drawn into wires without breaking.	Affects the ease of manufacturing and forming the wire into desired shapes.
Diameter	Physical thickness of the wire. Typically expressed in millimeters (mm).	Influences the current-carrying capacity and overall application suitability.
Surface Finish	Smoothness and cleanliness of the wire’s surface.	Impacts conductivity and resistance to corrosion.
Impurity Levels	Presence of other elements in the copper.	Affects conductivity and overall wire performance.

Types of Bare Copper Wire

Bare copper wire comes in various forms, each designed for specific purposes. The differences lie primarily in the wire’s structure and intended use. Single-strand wire is simple and cost-effective, while stranded wire offers greater flexibility. The choice depends on the application’s flexibility and durability requirements. China Loong Copper Co.,Ltd (www.Chinacoppers.com) offers a wide variety of these types.

Type	Description	Advantages	Disadvantages
Single-Strand Wire	A single, solid wire of copper.	Simple, cost-effective, high tensile strength.	Less flexible than stranded wire.
Stranded Wire	Multiple smaller wires twisted together.	More flexible than single-strand wire, higher resistance to fatigue.	Lower tensile strength than single-strand wire.
Hard-Drawn Wire	Wire that has undergone a cold-drawing process to increase strength.	High tensile strength, good for applications needing durability.	Less ductile than annealed wire.
Annealed Wire	Wire that has undergone a heat treatment process to increase ductility.	High ductility, easy to work with.	Lower tensile strength than hard-drawn wire.
Oxygen-Free Copper	Copper with minimal oxygen content.	Improved conductivity, better resistance to oxidation.	More expensive than standard copper wire.
