Tungsten Filament
Intervac stranded Tungsten wire coils and Baskets provide stable, Long life Resistance Heated sources for consistent dependable smooth evaporation of Aluminium and other metals in batch vacuum desposition processes.
Design Features
- High resistance to thermal and mechanical shock
- Configuration and dimensional tolerances strictly held in production quantities
- Constant composition and properties assured by closely controlled manufacturing processes.
- Controlled large grain wire for high density and minimum corrosion by active evaporants.
- Available with high temperature treatment for outgassing and dimensional stabilization, or with chemical cleaning.
- Available in low alkali tungsten
- Available with special stranding and with core type construction for uniform wetting and desposition
Application
- Batch or continuous vacuum desposition of metals on a wide variety of substrates including metal glass and plastics.
