With lamp components made of refractory metals from PLANSEE light has been made even more effective, economical and diverse.
High heat resistance, high purity and long service lifes are the most important requirements for the tools for lamp manufacturing. PLANSEE therefore offers a wide
range of components made of refractory metals and ODS-superalloys.
