copper clad steel sheet

Introduction

Copper clad steel sheets are a composite material that combines the corrosion resistance of copper with the strength and durability of steel. This innovative solution offers excellent mechanical properties and high conductivity, making it ideal for industries where both electrical performance and structural integrity are required. Baoji JL Clad Metals Materials Co., Ltd., with decades of expertise in producing clad materials, provides the top-quality steel sheets that meet international standards, offering reliability and cost-effectiveness to various industries.

Product Specifications

Copper Cladding Process

Copper-clad steel sheets are engineered by bonding a layer of copper onto a steel substrate, combining the unique properties of both metals. This hybrid material benefits from the strength, toughness, and formability of steel, while the copper layer provides excellent electrical conductivity and resistance to corrosion. Various techniques are used to create copper-clad steel sheets, offering solutions for a wide range of industrial applications.

Explosive Welding
Explosive welding is a high-energy bonding method in which an explosive charge is detonated between a copper layer and the steel base, causing them to collide at high speed. This results in a strong metallurgical bond between the two materials, forming a durable and reliable composite material.

Preparation: Both the copper and steel surfaces are meticulously cleaned and aligned before the explosive charge is applied.

Explosion: The explosive detonates, producing a high-speed impact that forces the materials to fuse, forming a solid bond.

Bonding Integrity: The explosion-induced collision causes the copper and steel to bond at the atomic level, ensuring a robust and long-lasting connection.

Explosive welding is particularly effective when there is a need for a high-strength bond in demanding applications such as heat exchangers, pressure vessels, and electrical components.

Roll Bonding
Roll bonding is a cold-working process in which copper and steel are passed through rollers under extreme pressure. The mechanical pressure deforms the materials, causing them to bond without the need for heat or chemical treatments.

Surface Preparation: Both the copper and steel are cleaned thoroughly to ensure that their surfaces are free of contaminants before bonding.

Rolling: The materials are fed through rollers, and the high pressure causes the copper and steel to fuse together.

Multiple Passes: Depending on the required strength and consistency, multiple passes through the rollers may be necessary to ensure a uniform and reliable bond.

Roll bonding is widely used for producing copper-clad steel sheets used in applications such as chemical processing, electrical equipment, and structural components.

Hot Isostatic Pressing (HIP)
Hot Isostatic Pressing (HIP) involves placing the copper and steel materials inside a sealed container, which is then exposed to high pressure and temperature. This process promotes the diffusion of atoms between the copper and steel layers, forming a homogeneous bond.

Encapsulation: Both layers are placed within a sealed environment to ensure complete contact and prevent contamination.

Pressurization: The sealed container is subjected to elevated temperatures and pressures, encouraging the copper and steel to form a solid atomic bond.

Diffusion Bonding: The result is a high-quality bond that improves the strength and performance of the copper-clad steel sheet.

HIP is commonly used in high-performance applications, such as aerospace, energy, and oil and gas sectors, where both material integrity and reliability are essential.

Features and Benefits

Corrosion Resistance
Copper-clad steel sheets provide exceptional resistance to corrosion, particularly in environments where the materials are exposed to chemicals or harsh conditions. The copper layer acts as a protective barrier against corrosion, while the steel provides structural strength.

Excellent Electrical Conductivity
The copper layer ensures high electrical conductivity, which is vital in applications such as electrical connectors, busbars, and circuit boards. This combination of conductivity and strength makes copper-clad steel sheets suitable for electrical power distribution and industrial electronics.

Thermal Conductivity
In addition to electrical conductivity, copper is an excellent conductor of heat. Copper-clad steel sheets are often used in heat exchangers and cooling systems, where efficient heat transfer is essential for performance.

Enhanced Strength and Durability
Steel provides mechanical strength and toughness, while copper adds resistance to wear and corrosion. This combination results in a highly durable material that is well-suited for high-stress environments, reducing the need for frequent replacements and maintenance.

Customization and Versatility
Copper-clad steel sheets can be customized to meet the specific needs of different industries. Parameters such as copper thickness, steel grade, and surface treatments can be adjusted to suit various applications, from electrical components to structural and chemical processing equipment.

Cost Efficiency
By combining copper with steel, manufacturers can take advantage of copper's properties at a lower cost compared to pure copper materials. Copper-clad steel sheets offer a cost-effective solution for industries where both conductivity and strength are required.

Improved Performance
Copper-clad steel sheets enhance the performance of equipment by combining copper’s ability to conduct electricity and heat with the mechanical robustness of steel. This results in materials that perform efficiently and reliably in demanding applications.
