Custom Copper Stainless Steel Clad Plate | Decorative & Structural Bimetal for Architecture, Cookware & Industrial Equipment

Custom Copper Stainless Steel Clad Plate

Introduction

1. Copper Stainless Steel Clad Plate is a bimetal composite that bonds a copper layer to stainless steel through roll‑bonding and diffusion bonding. The copper side offers excellent thermal conductivity, electrical conductivity, and a premium decorative finish, while the stainless steel side provides high strength, corrosion resistance, and good formability. This combination is widely used in architectural façades and interior panels, high‑end cookware and kitchen equipment, heat exchangers, electrical and electronic components, and decorative industrial parts where both performance and appearance are important.

2. We provide fully customizable Copper Stainless Steel Clad Plates, including total thickness, Cu/SS layer ratio, base grades (such as 304/304L/316L stainless with high‑conductivity copper), sheet size, and surface finish (brushed, mirror, patterned, or embossed). The plates feature strong metallurgical bonding, good machinability, and suitability for cutting, bending, stamping, and welding. Optional surface treatments and protective films are available to enhance corrosion resistance and protect the decorative copper surface during fabrication and installation. OEM/ODM services and engineering support are offered to match your drawings, processing requirements, and project specifications.

   Specifications

   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
   Form	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
