Characteristics and Applications of Copper-Coated Steel Fiber

Copper-coated steel fiber is a special composite material, usually achieved by electroplating or chemical plating a layer of copper onto the surface of steel fiber. This material combines the strength of steel fiber with the conductivity, corrosion resistance, and excellent thermal conductivity of copper, making it widely used in construction, concrete reinforcement, electromagnetic shielding, and conductive materials among other fields.

Characteristics of Copper-Coated Steel Fiber

High strength

Steel fiber itself has very high mechanical strength, which allows copper-coated steel fiber to enhance the load-bearing capacity of materials in engineering applications.

Excellent conductivity

The outstanding electrical conductivity of copper makes copper-coated steel fiber effective in scenarios requiring conductive capabilities (such as conductive concrete, lightning protection, etc.).

Corrosion resistance

The copper coating can effectively protect the steel fiber from environmental corrosion, especially in humid and acidic/alkaline environments.

Reinforcement

In construction materials (like concrete), copper-coated steel fiber significantly improves the crack resistance, wear resistance, and impact resistance of the materials when used as a reinforcing component.

Electromagnetic shielding

Due to its electrical conductivity, copper-coated steel fiber is often used in electromagnetic shielding materials, reducing interference from electromagnetic radiation.

Applications of Copper-Coated Steel Fiber

Concrete reinforcement materials

Copper-coated steel fiber can enhance the compressive and tensile properties of concrete, making it particularly suitable for structures requiring high wear resistance and crack resistance, such as bridges, tunnels, and airport runways.

Conductive concrete

Copper-coated steel fiber can be used in concrete materials that require electrical conductivity. It is applied in fields like electric heating floors and lightning protection.

Electromagnetic shielding

Copper-coated steel fiber can be used in electronic devices and building materials to shield electromagnetic radiation, reducing interference from external electromagnetic waves.

Anti-static materials

Copper-coated steel fiber can be used in industrial floors and devices that require anti-static properties to prevent static electricity accumulation.

Welding materials

Copper-coated steel fiber can also be used as a reinforcement in certain welding materials.

In summary, copper-coated steel fiber, with its excellent electrical properties, chemical resistance, and mechanical properties, has broad industrial and engineering application prospects.
