Import Cu Foil Evaporation Material — Buy in Bulk from Supplier in China

This CU foil evaporation material is manufactured from high-purity electrolytic copper with a minimum 99.95% Cu content, designed specifically for physical vapor deposition processes in thin film applications. The foil is supplied in standard thicknesses ranging from 0.025 mm to 0.1 mm, with a typical width of 100 mm to 300 mm and a length of up to 50 meters per roll. Surface roughness is maintained below 0.1 µm Ra to ensure uniform evaporation rates and consistent film adhesion.

The material is annealed to enhance ductility and reduce internal stresses, making it suitable for precise handling in vacuum chamber loading systems. It is packaged in moisture-resistant, nitrogen-flushed bags with desiccant to prevent oxidation prior to use. In industry practice, this grade of foil is commonly used in semiconductor wafer coating, solar cell electrode deposition, and optical thin film layers where electrical conductivity and thermal stability are critical.

Buyers in the electronics manufacturing sector, photovoltaic panel producers, and research labs in thin film technology source this material for its reliability in evaporation sources. It is typically shipped in sealed cartons, with standard packaging of 10 kg per box. Trade terms are available FOB Nanchang or CIF destination port, with lead times of 10 to 15 days after order confirmation. MOQ is negotiable based on volume and packaging preference.
