Production Method of Copper Clad Stainless Steel

Copper-clad stainless steel plates are typically produced using explosion bonding or roll bonding. In explosion bonding, a high-energy explosion forces the copper and stainless steel layers together under extreme pressure, creating a strong metallurgical bond at the interface. In roll bonding, the metals are heated and passed through rollers under high pressure to achieve bonding. Both techniques require surface area preparation (cleaning and degreasing) to ensure ideal attachment. Post-bonding, home plates might undertake heat treatment to boost bond stamina and mechanical residential or commercial properties. These methods ensure excellent bonding top quality, thermal and electrical conductivity, and rust resistance for commercial applications.

Storage Condition of Copper Clad Stainless Steel

Copper-clad stainless steel plates should be stored in a dry, clean, and well-ventilated environment to prevent moisture absorption and corrosion. The ideal storage temperature is between 10°C to 30°C (50°F to 86°F). Avoid exposure to high humidity, direct sunlight, or corrosive substances** such as acids, alkalis, or salt spray. Use protective packaging (e.g., VCI film or desiccants) to shield the plates from oxidation and contamination. Store them horizontally on flat racks or pallets to avoid deformation and ensure proper airflow. Regularly inspect for signs of corrosion, especially at the edges or bonding interface. Proper storage ensures the material retains its structural integrity, thermal/electrical conductivity, and performance.

5 FAQs of Copper Clad Stainless Steel

Q1

What is the production process of copper-clad stainless steel?

Answer: The production process of copper-clad stainless steel includes steps such as pretreatment of the stainless steel surface, cladding of copper or copper alloy, and subsequent processing. Pretreatment is mainly to clean and activate the surface of stainless steel, while cladding is to cover copper or copper alloy on stainless steel through methods such as welding or thermal spraying.

Q2

What is the electrical conductivity of copper-clad stainless steel?

Answer: The electrical conductivity of copper-clad stainless steel depends on the thickness and purity of the copper layer. Since copper is a good conductive material, copper-clad stainless steel has better electrical conductivity than ordinary stainless steel.

Q3

What is the corrosion resistance of copper-clad stainless steel?

Answer: The corrosion resistance of copper-clad stainless steel mainly depends on the protective effect of the stainless steel base material and the copper layer. The stainless steel base material has good corrosion resistance, and the copper layer can form a protective film to further improve corrosion resistance.

Q4

What is the processing performance of copper-clad stainless steel?

Answer: The processing performance of copper-clad stainless steel is similar to that of ordinary stainless steel, and it can be used for cutting, bending, welding and other processing operations. However, it should be noted that damage to the copper layer should be avoided during processing.

Q5

How environmentally friendly is copper-clad stainless steel?

Answer: The production process of copper-clad stainless steel requires control of waste water and exhaust gas emissions to ensure environmental protection. In addition, copper and stainless steel are recyclable metals, and waste can be recycled to reduce the impact on the environment.
