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…
