Product Description

What Is C2720 Pure Copper Plate?

C2720 Pure Copper Plate is high-grade flat copper sheet with Cu purity ≥99.9%, fully compliant with JIS H3100 standard. It features ultra-high purity, excellent electrical conductivity, thermal conductivity, good ductility, easy stamping, bending, welding and processing, smooth surface without oxidation, scratches or impurities. Widely used in electronics, electrical engineering, machinery manufacturing, heat dissipation, precision parts and industrial raw material supply.

C2720 99.9% Pure Copper Plate is a high-performance copper-zinc alloy plate with a copper content of 62.0–64.0% (99.9% pure copper base with zinc alloying), manufactured to JIS H3100, GB/T 5231, and UNS C27200 standards. It combines excellent mechanical strength, ductility, corrosion resistance, and electrical conductivity, making it ideal for industrial, electrical, and decorative applications. The plate features a smooth, defect-free surface, uniform microstructure, and consistent quality for reliable performance in diverse processing scenarios.

Core Advantages

High Purity & Precise Composition

Copper Content: 62.0–64.0% (Cu≥99.9% purity base, zinc as balance).

Impurity Control: Strictly limited impurities (Pb≤0.3%, Fe≤0.1%, Sb≤0.005%) for RoHS compliance and consistent performance.

Alloy Stability: CuZn37 (α+β dual-phase) structure ensures balanced strength and formability.

Superior Physical & Mechanical Properties

Density: 8.45 g/cm³ (20°C).

Electrical Conductivity: ≥24% IACS (resistivity ≤0.071 Ω·mm²/m).

Thermal Conductivity: 121 W/(m·K) for efficient heat dissipation.

Tensile Strength: 330–470 MPa; Elongation: ≥20% (soft temper).

Formability: Excellent cold/hot workability for stamping, bending, deep drawing, and welding.

Excellent Corrosion & Environmental Resistance

Resists atmospheric, freshwater, and mild chemical corrosion; forms a protective patina for long-term durability.

Low dezincification risk; stable in indoor and outdoor environments (avoid strong acidic/alkaline conditions).

Premium Surface Quality

Smooth, polished surface free of scratches, oxidation, nodules, or foreign contaminants.

Available in mill finish, brushed, or polished surfaces for decorative or functional use.

Production Process & Quality Control

Process: Raw material melting → continuous casting → hot rolling → cold rolling → annealing → surface treatment → precision cutting → inspection.

QC System: 100% inspection for chemical composition (XRF), dimensional accuracy (micrometer), surface quality (visual), and mechanical properties (tensile tester). Each batch includes a material test report (MTR) for traceability.

Application

Electrical & Electronic: Busbars, switch components, transformer parts, and conductive terminals.

Industrial Manufacturing: Precision stamping parts, fasteners (screws/nuts), springs, and hardware components.

Architectural & Decorative: Roofing, wall cladding, door frames, and decorative panels.

Heat Exchange: Radiators, heat sinks, and cooling system components.

Plating & Decoration: Base material for chrome/nickel plating (excellent adhesion).
