Pure copper (≥99.5% Cu) has one of the highest electrical conductivities among commercial metals (approximately 100% IACS). When used in electrical applications (busbars, connectors, grounding systems), the low resistivity minimizes energy loss as heat. Similarly, high thermal conductivity (≈400 W/m·K) makes it ideal for heat exchangers and solar reflective films where rapid heat transfer is required.

When exposed to air and moisture, copper naturally forms a protective patina layer (basic copper carbonate). This self-healing oxide layer prevents further corrosion, making copper sheets suitable for outdoor decorative cladding, roofing, and marine environments where steel would rust rapidly.

With ≥25% elongation and tensile strength ranging from 195–380 MPa, this copper sheet strikes an optimal balance between strength and ductility. The material can be:

• Bent without cracking for architectural flashings

• Punched for precision electrical components

• Cut to custom dimensions

• Welded for tank and vessel fabrication

• Deep drawn for utensil manufacturing

A:

• T2 (Pure Copper): ≥99.9% Cu, highest electrical/thermal conductivity, excellent corrosion resistance. Best for electrical and heat transfer applications.

• H62 (Brass): ≈62% Cu, 38% Zn. Lower cost, higher strength, good for decorative and mechanical parts.

• H65 (Brass): ≈65% Cu, 35% Zn. Similar to H62 but with slightly better corrosion resistance and formability.

A: Yes. We offer custom cutting, punching, and decoiling services. You can specify any width (0.1–1500mm) and length. Please provide your exact requirements when ordering.

A: We offer multiple surface options:

• Mill finish (as-rolled)

• Polished (mirror-like reflective surface)

• Brushed (satin, linear grain pattern)

• Anodized (for color and protection)

• Sand blasted (matte, textured)

• Powder coated (colored, durable finish)

A:

• MOQ: 500kg for plates; 300kg for strips/coils

• Lead time: Approximately 7–10 working days after deposit confirmation

A: We accept:

• L/C (Letter of Credit)

• T/T (30% deposit, 70% balance before shipment)

• Western Union

• PayPal

Price terms available: CIF, CFR, FOB, Ex-Work, CNF.

A: We use standard export seaworthy packaging:

• Waterproof paper + VCI anti-rust film

• Wooden pallets with edge protectors

• Steel strapping for container loading

• Labeling with product grade, dimensions, and quantity

A: Yes. Small sample pieces (e.g., 100×100mm or 200×200mm) are available. Sample costs are typically refundable upon confirmation of a bulk order. Contact our sales team to arrange.

A: Yes. Pure copper develops a protective patina over time when exposed to weather. This patina actually protects the underlying metal from further corrosion. Many customers use our 3mm–6mm sheets for roofing, exterior cladding, and architectural features that last decades.

A:

• Soft (Annealed): Maximum formability, deep drawing, complex bending

• 1/4 Hard: General forming, moderate strength

• 1/2 Hard: Balanced strength and formability

• Full Hard: Maximum strength, minimal forming (best for flat structural applications)

A: Yes. We can provide mill test certificates (MTC) and material test reports (MTR) confirming chemical composition, mechanical properties, and compliance with ASTM/JIS/ISO standards.
