Tungsten Sputtering Target

Tungsten Sputtering Target

钨溅射靶描述： Of all metals in pure form, tungsten has the highest melting point (3422℃, 6192 ℉), lowest vapor pressure (at temperatures above 1650℃, 3000 ℉) and the highest tensile strength. Although carbon remains solid at higher temperatures than tungsten, carbon sublimes at atmospheric pressure instead of melting, so it has no melting point. Tungsten has the lowest coefficient of thermal expansion of any pure metal. The low thermal expansion and high melting point and tensile strength of tungsten originate from strong covalent bonds formed between tungsten atoms by the 5d electrons. Tungsten Sputter Target used for Magnetron Sputtering Physical Vapour Deposition. Various diameters, thicknesses, and purities available to suit all major sputter source manufacturers. Materials are vacuum packed under cleanroom conditions to ensure zero contamination. Tungsten Sputtering Targets High purity tungsten targets with full density and homogeneous texture, high utilization rate, and greater efficiency
