Bare Copper Wire

Classification of  copper wire

Corrosion resistance: Pure copper has good corrosion resistance and can resist the attack of most chemicals. However, long-term exposure to acidic or alkaline environments may cause oxidation and corrosion.

Oxidation: Bare copper wires will gradually oxidize when exposed to air, forming an oxide film. This oxide layer usually appears blue-green, called patina or patina, but does not have a significant impact on the performance of the wire.

Chemical reaction: Bare copper wire reacts slowly with most non-oxidizing acids (such as hydrochloric acid and sulfuric acid) at room temperature, but will react violently with strong oxidizing acids such as concentrated nitric acid. In addition, bare copper wires will also react with alkaline substances such as alkali and ammonia.

Biocompatibility: Pure copper has good compatibility with most biological tissues and usually does not cause allergies or other adverse reactions. This has led to widespread use of bare copper wire in medical devices and biomedical applications.

The physical properties of bare copper wire include the following aspects:

 Conductivity: Copper is an excellent conductive material, and bare copper wire has a very high conductivity, typically between 58 and 65 MS/m (millions of Siemens per meter). This means that bare copper wires can effectively conduct current and reduce resistive losses.

 Thermal conductivity: Copper is also a good thermal conductive material. Bare copper wire has good thermal conductivity and can effectively transfer heat.

 Flexibility: Bare copper wire is typically very flexible and bends and bends easily, making it suitable for a variety of applications that require bending or folding.

 Tensile strength: Bare copper wire has high tensile strength and can withstand a certain degree of tensile force without breaking or deforming.

 Hardness: Copper has a low hardness, so bare copper wire is usually softer. This contributes to its flexibility and ease of workability.

 Density: Bare copper wire has a density of approximately 8.96 grams/cubic centimeter, which means it is relatively heavy, but in most applications this is not an important consideration.

 Melting point: The melting point of copper is approximately 1083 degrees Celsius (1981 degrees Fahrenheit), which means that bare copper wire can maintain its structure and performance in high-temperature environments.

 Magnetism: Copper is a non-magnetic material, so bare copper wire is not affected by external magnetic fields, making it suitable for applications requiring stable magnetic properties.
