Copper sheets play a vital role in various industries due to their excellent electrical conductivity, corrosion resistance, and ductility. As a leading copper sheet supplier, Jindalai Steel Group Co., Ltd. is committed to providing high-quality copper sheets that meet diverse specifications and application requirements.
When discussing copper sheet specifications, understanding the various sizes and thicknesses is crucial. Copper sheets are typically produced in standard sizes, with thicknesses ranging from 0.5 mm to 100 mm (commonly 0.5–10 mm) and widths from 600 mm to 2000 mm, with custom cutting available. Lengths are typically 1 m, 1.5 m, 2 m, etc., and custom length processing is supported.
The most commonly used grades include T1, T2, T, T4, TU1, TU2, TP1, and TP2.
Copper purity ≥99.9% — High electrical conductivity (IACS ≥96%), excellent thermal conductivity, and good ductility. Commonly used in wires and cables, motor windings, transformer coils, printed circuit boards (PCBs), and architectural decoration (such as roofing and wall coverings).
Copper purity ≥99.95%, oxygen content ≤0.003% — No hydrogen embrittlement, extremely high conductivity (IACS ≥101%), excellent weldability. Commonly used in high-precision electronic components (such as semiconductor lead frames), vacuum equipment seals, and aerospace cooling pipes.
Copper purity ≥99.9%, phosphorus-deoxidized — Strong corrosion resistance, excellent weldability, suitable for high-temperature environments. Commonly used in heat exchangers, water heater liners, chemical pipelines, and ship fittings.
From a metallurgical perspective, cold rolling and hot rolling are not only different in process, but also in their crystal structure and internal stress.
Because it is processed at room temperature, the surface undergoes work hardening, resulting in extremely high gloss. For those making precision electronic components or decorative panels, cold-rolled sheets are a lifesaver — ready to use, no pickling or milling required.
Processed at high temperatures, inevitably resulting in oxide scale (black scale) on the surface. If your project involves heavy-duty busbars or structural components, this oxide scale is negligible; it can be milled off during machining. However, if you’re making exterior parts, this scale is a nightmare. Removing it not only increases tool wear but also adds an extra pickling or milling step, increasing costs by at least 20%–30%.
In short, copper sheets are critical components across various industries, and understanding their specifications, grades, and applications is crucial for making informed purchasing decisions. As a leading copper sheet supplier, Jindalai Steel Group Co., Ltd. offers a complete range of products, all meeting the highest quality standards.
With a customer-first philosophy and professional guidance, Jindalai Steel Group Co., Ltd. is the ideal choice for all your copper sheet needs. Whether you need copper sheets for electrical applications, construction projects, or special manufacturing processes, Jindalai Steel Group Co., Ltd. can provide high-quality products that meet your specifications and exceed your expectations.
