Aluminum-chromium | Plansee
During the coating process, our targets and anodes are exposed to high temperatures. However, our material doesn''t feel the heat. Thanks to their aluminum content and high material density, our hodes and targets offer particularly high thermal conductivity and can easily transfer the heat to a copper plate loed behind them. If heat is allowed to build up, the target material is removed
