In today’s era of rapid technological development, various new materials are steadily emerging to meet changing application needs. Copper-clad steel is one such eye-catching material. It combines copper’s excellent electrical conductivity with steel’s strength, making it an engineering material with great potential. This article will detail the characteristics, applications and development prospects of Copper Clad Steel.

Features of Copper Clad Steel

  1. Electrical conductivity: Copper-clad steel has better electrical conductivity than steel because it covers a layer of copper on the surface of the steel. Copper’s electrical conductivity is the best-known metal, so copper-clad steel has many applications in manufacturing power transmission and electronic equipment.
  2. Strength and hardness: Although the copper layer increases the material’s conductivity, it does not reduce the strength and hardness of the steel. In fact, due to copper’s hardness and wear resistance, copper-clad steel exhibits greater strength and hardness in specific applications.
  3. Corrosion resistance: The copper layer can effectively prevent the steel from coming into contact with the external environment, thereby reducing the corrosion rate. Therefore, copper-clad steel has better corrosion resistance than ordinary steel.

Applications of Copper Clad Steel

  1. Power transmission and distribution: Because copper-clad steel has excellent electrical conductivity, strength and corrosion resistance, it has been widely used in power transmission and distribution. For example, it can be used to make equipment such as wires, cables, and transformers. These devices must operate at high currents and voltages, and copper-clad steel can provide stable electrical conductivity and high mechanical strength to ensure the reliability and safety of the equipment.
  2. Electronic equipment manufacturing: In electronic equipment manufacturing, copper-clad steel can manufacture components such as printed circuit boards, connectors, and terminals. Its excellent electrical conductivity and corrosion resistance allow it to perform better in these devices. In addition, because copper-clad steel has high hardness and wear resistance, it can also be used to manufacture parts that need to withstand more significant pressure and friction, such as connectors and terminals.
  3. Offshore engineering and oil and gas extraction: In offshore engineering and oil and gas extraction, equipment and structures must withstand the effects of high humidity, salt spray and corrosive environments. The corrosion resistance and strength of copper-clad steel make it ideal for these applications. It can manufacture electrical equipment, oil pipelines, natural gas pipelines, etc., on offshore platforms to ensure stable operation in harsh environments.
  4. Construction and building structures: In construction and building structures, copper-clad steel can manufacture structural supports, connectors, lightning protection systems, etc. Its excellent electrical conductivity and corrosion resistance allow it to effectively transmit electric current and prevent building damage by lightning strikes. In addition, the high strength and hardness of copper-clad steel can also be used to manufacture parts that need to withstand greater loads and vibrations.
