Description
Tungsten is renowned for its extremely high melting point, exceeding 3400°C, which ensures its stability and durability even under extreme thermal conditions. This high melting point allows Tungsten evaporation materials to withstand the intense heat required for evaporation, ensuring a smooth and uniform deposition process. Moreover, Tungsten exhibits excellent hardness and mechanical strength, making it highly resistant to wear and deformation. This robustness ensures that Tungsten evaporation materials maintain their integrity and performance throughout the evaporation process, providing reliable and consistent results.
Additionally, Tungsten is known for its excellent electrical conductivity and thermal conductivity. These properties enable Tungsten evaporation materials to efficiently conduct heat and electricity during evaporation, resulting in improved process efficiency and higher-quality coatings. Furthermore, Tungsten evaporation materials possess good chemical stability and are resistant to corrosion and oxidation. This ensures that they maintain their original properties and performance over a long period, even in harsh environments.
