Product overviewPlansee supplies narrow molybdenum (Mo) and molybdenum‑yttrium oxide (MY) ribbons designed for forming tubular crimp connectors used as welding aids in lamp production. These tubes enable reliable joining of tungsten filaments to molybdenum‑lanthanum‑oxide (ML) support pins; MY ribbons offer improved weldability compared to pure Mo.
Function / ProcessThe ribbon is formed into a tube placed over the tungsten filament end, mechanically crimped to fix it, then welded to the ML pin to create the electrical and mechanical joint. The product is optimized for automated tube forming and series assembly processes.
