About SCHLENK
Schlenk SE, headquartered in Barnsdorf (Roth, Bavaria), is a metal-processing family business that has existed since 1879. The company produces metallic effect pigments (aluminium pigments, gold bronze pigments, vacuum-metallized pigments), technical aluminium and copper or copper alloy powders, as well as ultra-thin metal foils and strips made of copper, copper alloys, nickel, nickel silver, resistance alloys, and fine silver. Manufacturing includes, among other things, powder production, foil production in the company's own rolling mill, and conversion into battery foils, photovoltaic connectors, and copper sinter pastes (CuNex). Customers include the paints, printing inks, plastics, cosmetics, chemicals, and building materials industries (autoclaved aerated concrete) as well as the solar, battery, and power electronics industries. In addition to several plants in Germany (Roth, Neuhaus/Rothenbruck, Bitterfeld), the company operates production sites in the Czech Republic (Bojkovice), Slovenia (Kamnik), and China (Jiangsu) and supplies customers in over 100 countries.
