Laminating foil

laminatedmetalaluminum

Copper foils: used in new generation lithium-ion batteries. Silver foils: produced for special batte- ries requiring speific electrochemical re- actions. Copper alloy foils: used in batteries that have to withstand extreme mechanical and thermal stress. Applications Li-on Military batteries Special batteries Supercapacitors Silver MATERIAL Silver (up to 99.99% purity with impurity control in PPB); perfectly degreased surfaces suitable for coating THICKNESS Thicknesses from 8 my; thickness tolerance up to +/- 3%; minimum width 1 mm FORMATS Plastic flanges available for each coil; coils also available in reduced widths; customised shapes available on request MECHANICAL PROPERTIES Hard foils with HV> 75; mechanical properties with narrow tolerance ranges for special applications. SURFACE Specular surface with very low roughness level; the absence of surface impurities guarantees the highest level of polishability; anti- scratch protection film available Copper MATERIAL Different types of copper available depending on the required properties FORMATS Packaging made of vacuum rolled barrier; on request protection against oxidising agents, barrier bag and other special packaging. MECHANICAL PROPERTIES Tensile strength up to > 800 MPa Guaranteed mechanical resistance up to 200°C SURFACE Low roughness (<0.1my Ra); Tin plating and silver plating on request opper Alloy MATERIAL 4 types of brass (CuZn), 2 types of bronze (CuSn), 2 types of nickel silver (CuNiZn) and other special alloys with high heat resistance
