鎢及鎢合金 Tungsten and Alloys
作為熔點(diǎn)最高(3460℃)和蒸氣壓最低的金屬,鎢廣泛應(yīng)用于高溫加熱、照明、航空航天以及半導(dǎo)體設(shè)備及器件等領(lǐng)域。
As the metal of the highest melting point and the the lowest evaporation rate, tungsten metal and its alloys are widely used in fields of heating,lighting, aerospace, and also semiconductor sets.
艾默特,采用優(yōu)質(zhì)原料,利用熱擠壓、鍛造或軋制工藝,為客戶提供各類鎢及鎢合金材料及制品。
High - quality molybdenum and tungsten final products are made and supplied.
These products are produced by by powder metallurgical processes, such as hot extrusion,hot rolling and wrought, these manners make sure our advantages in qulity, price and delivery time.
