Custom Copper Stainless Steel Clad Plate | High-Performance Bimetal for Architecture, Cookware & Industrial Engineering

Custom Copper Stainless Steel Clad Plate

Introduction

1. Our Copper Stainless Steel Clad Plate is a high-performance bimetal composite produced through advanced roll-bonding and diffusion technology, ensuring a permanent and seamless metallurgical bond between the layers. This material uniquely combines the exceptional thermal and electrical conductivity of copper with the high mechanical strength, rigidity, and superior corrosion resistance of stainless steel. It is the ideal solution for applications requiring efficient heat distribution, such as high-end multi-ply cookware and industrial heat exchangers, as well as for electrical components and busbars where weight and cost need to be optimized without sacrificing surface performance.

2. We offer fully customizable Copper Stainless Steel Clad Plates tailored to your specific project requirements, including adjustable total thickness, cladding ratios (e.g., 10/90, 20/80), and a variety of material grades like C11000 copper paired with 304 or 316L stainless steel. Beyond industrial use, these plates are highly valued in the architectural and interior design sectors for their premium aesthetic appeal, offering the warm patina of copper with the structural integrity of steel. Our plates support a wide range of processing methods, including deep drawing, laser cutting, bending, and CNC machining, and can be supplied with various surface finishes such as brushed, mirror, or protective PE films to suit your fabrication needs.

   Spécifications

   Type	Copper–Stainless Steel Clad Plate / Sheet / Panel / Bimetal Composite
   Structure	Metallurgically bonded Cu–SS composite: typically Cu/SS or SS/Cu/SS layered structures produced by solid‑state roll‑bonding and diffusion bonding
   Material Grade	High‑conductivity copper (e.g., T2, C11000, C12200) clad to stainless steels such as 304, 304L, 316, 316L, 430 or other architectural/industrial stainless grades
   Cu/SS Ratio (Thickness)	Customizable copper and stainless thickness ratio (e.g., 5/95, 10/90, 20/80, 30/70, 50/50 etc.), optimized for thermal/electrical performance, strength, appearance, and cost
   Thermal & Electrical Props.	Copper layer provides excellent thermal and electrical conductivity; stainless steel layer offers high strength, stiffness, and good heat/corrosion resistance
   Formulaire	Flat plate, sheet, coil, or cut panels; supplied as mill sheets, decorative panels, cookware blanks, or machined components
   Thickness Range	Customizable total thickness, typically from about 0.5 mm to 20 mm or more; individual Cu and SS layer thicknesses adjustable according to design, mechanical load, and heat transfer requirements
   Width & Length	Sheet width typically up to 1,000–1,500 mm (depending on thickness and grade); length as standard sheets or cut‑to‑size plates according to customer specifications
   Bonding Method	Solid‑state roll bonding (explosion or hot‑roll bonding also available from some producers) followed by thermal treatment/diffusion bonding to form a continuous, high‑strength metallurgical interface between copper and stainless
   Interface Quality	High bonding strength, uniform cladding, low interface resistance, and good shear/peel strength, suitable for cookware, heat exchangers, architectural and electrical applications
   Mechanical Properties	Good overall strength and toughness; stainless side provides rigidity and wear resistance, copper side provides high ductility and excellent formability for bending, deep drawing, and spinning (grade‑dependent)
   Density & Cost Balance	Bimetal design reduces the amount of copper required while maintaining a copper working surface, lowering material cost compared with solid copper plates at equivalent stiffness
   Surface Finish	As‑rolled, brushed (hairline), satin, matte, mirror‑polished, patterned or embossed; copper side and stainless side can be supplied with different finishes for functional or decorative purposes
   Surface Treatment	Degreased and cleaned as standard; optional anti‑oxidation/anti‑tarnish treatment for copper side, passivation for stainless side, protective PE film for façade and decorative panels, or surface preparation for later coating
   Weldability & Joining	Compatible with TIG/MIG welding, resistance welding, brazing, and soldering (process selection and joint design should consider bimetal structure); can also be riveted, bolted, or adhesive‑bonded
   Corrosion & Wear Resistance	Stainless steel layer provides excellent corrosion and wear resistance in many indoor and outdoor environments; copper side can patinate or be clear‑coated/treated depending on architectural or decorative requirements
   Dimensional Tolerances	Tight control of thickness, flatness, and surface quality to ensure stable forming, good contact between layers in heat‑transfer equipment, and consistent appearance in architectural applications
   Standards & Reference	Manufactured with reference to copper and stainless steel standards (e.g., ASTM B152/B467 for copper, ASTM A240/A480 for stainless sheet/plate, EN/GB equivalents) and relevant composite plate specifications on request
   Application Range	Architectural façades and interior wall panels, elevator and lobby decoration, high‑end cookware and kitchenware, heat spreaders and heat exchangers, power and electronic components, decorative panels, and industrial cladding
   Processing Capability	Supports shearing, sawing, laser cutting, water‑jet cutting, CNC profiling, bending, rolling, stamping, deep drawing and spinning (depending on structure and thickness); suitable for both manual and automated fabrication lines
   Customization	Tailored Cu/SS structure, thickness, sheet size, base grades, surface finish, pattern/embossing, and pre‑cut or pre‑formed geometries according to drawings or CAD files
   Packaging	Supplied as palletized sheets or coils with edge protection; interleaved paper or film between sheets; PE protective film on visible surfaces; wooden case or crate packaging for export and long‑distance transport
