Rolled Copper Foils

  • High-precision RA Copper Foil

    High-precision RA Copper Foil

    High-precision rolled copper foil is a high-quality material produced by CIVEN METAL. Compared to ordinary copper foil products, it has higher purity, better surface finish, better flatness, more precise tolerances and more perfect processing properties.

  • Treated RA Copper Foil

    Treated RA Copper Foil

    Treated RA copper foil is a single side roughened high precision copper foil in order to increase its peel strength. The roughened surface of copper foil likes a frosted texture, which makes it easier to laminate with other materials and less likely to peel off. There are two mainstream treatment methods: one is called reddening treatment, where the main ingredient is copper powder and the surface color is red after treatment; the other is blackening treatment, where the main ingredient is cobalt and nickel powder and the surface color is black after treatment.

  • Nickel Plated Copper Foil

    Nickel Plated Copper Foil

    Nickel metal has high stability in air, strong passivation ability, can form a very thin passivation film in air, can resist the corrosion of alkali and acids, so that the product is chemically stable in work and alkaline environment, not easy to discolor, can only be oxidized above 600 ℃; nickel plating layer has strong adhesion, not easy to fall off; nickel plating layer can make the surface of material harder, can improve the product wear resistance and acid and alkali corrosion resistance, the product wear resistance, corrosion, rust prevention performance is excellent.

  • Tin Plated Copper Foil

    Tin Plated Copper Foil

    Copper products exposed in the air are prone to oxidation and the formation of basic copper carbonate, which has high resistance, poor electrical conductivity and high power transmission loss; after tin plating, copper products form tin dioxide films in the air due to the properties of tin metal itself to prevent further oxidation.

  • Beryllium Copper Foil

    Beryllium Copper Foil

    Beryllium Copper Foil is one kind of supersaturated solid solution copper alloy which combined very good mechanical ,physical, chemical properties and corrosion resistance. It has high intensity limit, elastic limit, yield strength and fatigue limit as special steel after solution treatment and aging.

  • Copper Nickel Foil

    Copper Nickel Foil

    The copper-nickel alloy material is commonly referred to as white copper because of its silvery white surface. copper-nickel alloy is an alloy metal with a high resistivity and is generally used as an impedance material. It has a low resistivity temperature coefficient and a medium resistivity (resistivity of 0.48μΩ·m). Can be used over a wide temperature range.

  • RA Copper Foils for FPC

    RA Copper Foils for FPC

    Copper foil for circuit boards is a copper foil product developed and produced by CIVEN METAL specifically for the PCB/FPC industry. This rolled copper foil has high strength, flexibility, ductility and surface finish, and its thermal and electrical conductivity is better than similar products.

  • Rolled Copper Foils for Battery

    Rolled Copper Foils for Battery

    The Battery Rolled Copper Foil is a cathode material produced by CIVEN METAL specifically for high-end batteries. The uniform thickness and flat shape of the copper foil makes it easy to coat and not to peel off;

  • RA Bronze Foil

    RA Bronze Foil

    Bronze is an alloy material made by melting copper with some other rare or precious metals. Different combinations of alloys have different physical properties and applications.

  • RA Brass Foil

    RA Brass Foil

    Brass is an alloy of copper and zinc, which is commonly known as brass because of its golden yellow surface colour. The zinc in brass makes the material harder and more resistant to abrasion, while the material also has a good tensile strength.

  • RA Copper Foil

    RA Copper Foil

    The metal material with the highest copper content is called pure copper. It is also commonly known as red copper because of its surface appears reddish-purple colour. Copper has a high degree of flexibility and ductility. It also has excellent electrical and thermal conductivity.
