Copper plate is a flat-rolled copper product with a rectangular cross-section, typically manufactured through hot rolling followed by cold rolling and annealing processes. It offers outstanding electrical and thermal conductivity, excellent corrosion resistance, good formability, and high ductility, making it an essential material for electrical equipment, industrial machinery, roofing, and decorative applications. Common international standards include ASTM B152 (USA for copper sheet, strip, and plate), EN 1652 (Europe for general copper flat products), JIS H3100 (Japan for copper and copper alloy sheets, plates, and strips), and BS 2870 (UK). Typical grades include C11000 (electrolytic tough pitch copper), C12200 (phosphorus-deoxidized copper), Cu-ETP (EN equivalent to C11000), and C1100 (JIS equivalent). To compare copper plate standards across regions, search “copper plate ASTM B152 vs EN 1652 comparison”; for electrical conductivity data, use “C11000 copper plate conductivity IACS chart”; to check standard thickness and width ranges, search “copper plate common size chart ASTM”; for alloy selection guidance, use “C11000 vs C12200 copper plate application guide”.
China’s domestic standards for copper plates mainly follow GB/T 2040 (copper and copper alloy plates) and GB/T 2059 (copper and copper alloy sheets, plates, and strips). Common Chinese grades include T2 (pure copper, equivalent to C11000), TP2 (phosphorus-deoxidized copper, equivalent to C12200), TU1 (oxygen-free copper), and H62 (brass, 62% copper). Copper plates are available in thicknesses ranging from 0.5mm to 50mm, with widths from 200mm to 3000mm and lengths from 500mm to 6000mm. To cross-reference Chinese grades with international equivalents, search “T2 copper plate equivalent ASTM”; for Chinese copper plate dimension tables, use “GB/T 2040 copper plate size list”; to verify mechanical property requirements, search “Chinese copper plate tensile strength hardness chart”; for a sample Chinese mill test certificate, use “China copper plate MTC example”.
Copper plates are widely used in the electrical and power industries (bus bar plates, switchgear panels, transformer components, and grounding plates), industrial machinery (gaskets, heat exchanger plates, and reaction vessel linings), architectural applications (roofing sheets, wall cladding, flashing, expansion joints, and decorative fascias), and printing industries (engraving plates and photogravure cylinders). For electrical applications, C11000 (T2) is preferred due to its minimum 101% IACS conductivity; for roofing and architectural use, C12200 (TP2) offers better resistance to atmospheric corrosion and is more suitable for soldering and brazing. To select copper plate for electrical bus bar applications, search “copper plate for bus bar specification ASTM B152”; for roofing and cladding requirements, use “C12200 copper plate for architectural roofing”; to review heat exchanger plate standards, search “copper plate for heat exchanger manufacturing”; for decorative and printing application examples, use “copper plate for engraving and photogravure fabrication”.
When sourcing copper plates internationally, critical parameters include grade, temper designation (annealed, quarter-hard, half-hard, or full-hard), thickness and width/length tolerances, flatness, surface finish (mill finish, polished, brushed, or coated), and edge condition (sheared edge, saw-cut edge, or machined edge). Also confirm whether the plate is suitable for deep drawing, bending, or machining applications, and whether surface protection (protective film or oil coating) is required to prevent oxidation during storage. For dimensional tolerance standards, search “copper plate thickness tolerance ASTM B152”; to compare temper conditions for forming applications, use “annealed vs half-hard copper plate formability”; for current international pricing trends, search “copper plate price per kg 2025”; to locate certified global suppliers, use “copper plate manufacturers Europe directory”.
