T2 Pure Copper Plate/Sheet Copper Block Laser Cut Many Sizes 0.5mm to 8mm Thick

Thin sheets (0.3–1 mm) are well-suited for flexible applications such as shielding foil, craft work, jewelry, and light-duty gaskets. Mid-range thicknesses (1.2–3 mm) work well for bus bars, grounding straps, heat spreaders, and structural brackets. Thicker stock (3.5–8 mm) is appropriate for heavy-duty electrical contacts, machined blocks, and applications requiring significant mechanical strength. If you are unsure, contact us with your load or current requirements and we can advise.

Yes. T2-grade copper is one of the most widely used materials for electrical bus bars due to its low resistivity and high current-carrying capacity. For bus bar applications, thicknesses of 2 mm and above are typically recommended. The exact current rating depends on the cross-sectional area, ambient temperature, and ventilation — consult an electrical engineer for safety-critical installations.

Bare copper naturally oxidizes when exposed to air and moisture, developing a darkened or greenish patina over time. This patina is a stable copper oxide/carbonate layer that actually slows further corrosion. For applications where a bright surface must be maintained (e.g., decorative work), apply a clear lacquer or wax after cleaning. For electrical contacts, light sanding or a contact cleaner restores conductivity if oxidation builds up.

Yes. T2 copper is highly solderable with standard rosin-core or water-soluble flux solders, and it can be brazed using copper-phosphorus or silver-based brazing alloys. For best results, clean the surface with isopropyl alcohol or a mild abrasive before soldering to remove any surface oxide. No special pre-treatment is required beyond standard copper preparation practices.

Copper can be CNC-milled, drilled, and filed using standard carbide tooling, though its ductility means sharp tools and appropriate feed rates are important to avoid galling. For laser engraving, copper's high reflectivity means fiber lasers are generally more effective than CO₂ lasers. Chemical etching (ferric chloride) is another popular method for fine detail work on thinner sheets.

The quantity option lets you order multiple identical pieces in a single transaction, which is useful when you need matched pairs (e.g., two grounding plates) or a small batch for prototyping. Ordering 4 pieces of a smaller size is often more economical per piece than ordering one large sheet and cutting it yourself, especially for sizes like 50 × 50 mm where the per-unit price is lower. Check the variant pricing to compare options before adding to cart.

T2 is the Chinese national standard designation for electrolytic tough pitch copper, which is functionally equivalent to ASTM C11000 (C110) and very close to EN CW004A. All three designations refer to copper with ≥99.9% purity and similar electrical and thermal properties. T2 / C110 is the most common commercial copper grade and is suitable for the vast majority of electrical, thermal, and fabrication applications.
