钨及钨合金 Tungsten and Alloys
作为熔点最高(3460℃)和蒸气压最低的金属,钨广泛应用于高温加热、照明、航空航天以及半导体设备及器件等领域。
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,采用优质原料,利用热挤压、锻造或轧制工艺,为客户提供各类钨及钨合金材料及制品。
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.
