Properties of Wrought HC Copper

Wrought high-conductivity (HC) copper, often referred to as electrolytic tough pitch (ETP) copper, is a type of copper alloy with excellent electrical conductivity and mechanical properties. Here are the key properties of wrought HC copper:

1. Electrical Conductivity: Wrought HC copper is renowned for its exceptional electrical conductivity, making it one of the most conductive metals available. It typically exhibits a conductivity of around 100% IACS (International Annealed Copper Standard), meaning it conducts electricity with minimal resistance.

2. Thermal Conductivity: In addition to its outstanding electrical conductivity, wrought HC copper also possesses excellent thermal conductivity. This property makes it suitable for applications where efficient heat dissipation is crucial, such as in electrical contacts and heat sinks.

3. Mechanical Properties: Wrought HC copper offers good mechanical properties, including high tensile strength, yield strength, and ductility. These properties make it easy to fabricate and form into various shapes and sizes without sacrificing its electrical conductivity.

4. Corrosion Resistance: HC copper exhibits good resistance to corrosion in most environments, particularly in freshwater and atmospheric conditions. However, it may corrode in certain aggressive environments or when exposed to acidic or alkaline solutions over extended periods.

5. Malleability and Ductility: Wrought HC copper is highly malleable and ductile, allowing it to be easily formed, bent, and shaped without the risk of cracking or fracturing. This property is advantageous for manufacturing processes such as drawing, bending, and stamping.

6. Annealing: HC copper can be annealed to improve its mechanical properties and facilitate further processing. Annealing involves heating the copper to a specific temperature and then gradually cooling it to relieve internal stresses and increase its ductility.

7. Weldability: Wrought HC copper can be welded using various techniques, including soldering, brazing, and gas tungsten arc welding (GTAW). Proper surface preparation and selection of suitable welding methods are essential to ensure strong and durable joints.

8. Recyclability: Like other copper alloys, wrought HC copper is highly recyclable, meaning it can be melted down and reused without losing its original properties. Recycling copper helps conserve natural resources and reduces energy consumption compared to primary production.

Overall, wrought high-conductivity copper combines excellent electrical conductivity, thermal conductivity, mechanical properties, and corrosion resistance, making it an ideal choice for a wide range of electrical and electronic applications, including electrical wiring, busbars, electrical contacts, connectors, and heat exchangers.
