Four-Strand Twisted Tungsten Heater
Four-strand twisted tungsten heater is a tungsten heating element formed by precision twisting four high-purity tungsten wires or doped tungsten wires. It can be further bent into spiral, M-shaped, or hump-shaped configurations.
Through its four-strand twisted structure, CTIA’s tungsten heater offers the following features:
(1) Higher structural strength: Compared with single-strand or double-strand structures, the four-strand twisted design provides higher tensile strength and improved anti-sag capability.
(2) More uniform current distribution: Multi-strand conductive paths help distribute current density more evenly and reduce localized hotspot risks.
(3) Better thermal stability: The twisted structure provides flexibility, which helps relieve thermal stress caused by expansion.
(4) Stronger material loading capacity: It is suitable for carrying larger amounts or larger-sized evaporation materials.
The four-strand twisted tungsten heater maintains good structural stability under high-temperature vacuum environments and is suitable for long-duration or high-load operating conditions.
As a typical evaporation source element, CTIA tungsten heater is widely used in:
(1) Vacuum coating: Used for evaporation of metals such as aluminum and chromium, ensuring stable evaporation performance.
(2) Optics and display: Used for optical thin films and display device coating, improving film uniformity.
(3) Electronic manufacturing: Used for metal electrode or functional thin-film deposition.
(4) High-temperature heating: Used in vacuum furnaces or localized high-temperature heating applications.
