Durable single or double side copper clad stainless steel plates with excellent conductivity, corrosion resistance, and formability for electronics, appliances, and aerospace.
When you need a material that delivers both electrical conductivity and structural strength, copper clad stainless steel plates are the smart choice. By combining a stainless steel base with one or two layers of copper, these clad plates balance performance, cost, and durability in ways that neither pure copper nor pure stainless steel can achieve alone.
At Hebei Yuguang Welding Co., Ltd, we specialize in manufacturing single-side and double-side copper clad stainless steel composite plates for industries ranging from household appliances to automotive, aerospace, energy, and electronics. With decades of metallurgical expertise, we supply global OEMs and industrial clients with materials engineered to meet high standards of performance.

Note:
The thickness of the copper or stainless steel is not limited to the table; it can be adjusted based on customer’s requirement. One side of the copper or stainless steel can be different from the other.
High Strength & Elasticity: The stainless steel base provides structural strength and elasticity, ensuring long-term durability.
Excellent Plasticity & Formability: Easy to process by stamping, bending, and deep drawing.
Superior Oxidation & Corrosion Resistance: Suitable for environments where moisture, heat, or corrosive substances are present.
Outstanding Thermal & Electrical Conductivity: Copper layers ensure reliable current flow and efficient heat transfer.
Recyclability: Fully recyclable material, aligning with sustainability goals.
Cost Efficiency: Offers a cost-effective alternative to pure copper, without compromising conductivity or mechanical strength.
Compared to pure stainless steel: Provides much higher electrical and thermal conductivity.
Compared to pure copper: Stronger, more wear-resistant, and less expensive, especially for large-scale use.
Compared to plating methods: Clad bonding is more durable, with no risk of peeling or uneven coating.
