Hairpin Type Tungsten Heater
1. What Is a Hairpin Type Tungsten Heater?
A hairpin type tungsten heater is a compact tungsten heating element fabricated by bending high-purity tungsten wire with purity of 99.95% or higher or doped tungsten wire into a U-shaped configuration. It is also referred to as a U-type or U-shaped tungsten heater. The tungsten heaters are typically manufactured from single-strand tungsten wire with a diameter of 0.2 to 2.0 mm or 2 to 4 strand twisted tungsten wire, and can be configured into multi-U arrays to accommodate specific vacuum heating volumes and equipment requirements.
2. Advantages of CTIA’s Hairpin Type Tungsten Heater
