CTIA's Tungsten Heater in Metallization Coating
Tungsten heater is a resistive heating component fabricated from high-purity tungsten wire through precision stranding, coiling, forming, and surface treatment processes. The heating element is utilized in vacuum evaporation coating equipment to heat and vaporize metals such as aluminum, copper, and tin, enabling stable metallization on plastic, ceramic, glass, and metal substrates.
Metallization processes require strong coating adhesion and uniform surface finish, making heater stability critical to film quality. CTIA’s tungsten heater offers excellent high-temperature stability, with tungsten’s melting point of 3410°C ensuring reliable performance across various metal evaporation processes. Low vapor pressure under high vacuum minimizes contamination from material volatilization and improves coating cleanliness. Optimized surface treatment enhances wettability with metals such as aluminum and tin, reducing spitting and improving evaporation uniformity. Refined grain structure increases creep resistance, maintaining stable geometry during repeated thermal cycling.
Specifications of CTIA's tungsten heater in the metallization coating are as follows:
