2. Application:
Tungsten crucible are heavy and fragile,lift slowly and steadily using high strength hoisting soft belt
tungsten crucible must be stored in a dry area(humidity less than 60%),otherwise they are easy to be oxidized
when setting up the tungsten crucible,the support structure and base should be always horizontal not only at room temperature but also at working temperature to ensure the crucible is not skewed while working
3. Quality control
composition analysis,particle size distribution are tested for each batch of tungsten powder befor putting into production
Measuring density for each tungsten crucible,re-sintering if the density is low
Size inspection logged for each tungsten crucible
ultrasonic flaw detection for each tungsten crucible to ensure homogeniety and flaw-free
suitable for producing ion implantation parts.electric light source parts and electric vacuum components,heating elements and refractory parts in high temperature furnaces,used as electrodes in the field of rare earth metal industry
is regular black covered with graphite,metallic luster after graphite removed.
for producing electric light source parts and electric vaccum components,heating elements and refractory parts in high temperature furnaces,heating elements used in vacuum metalizing or plating.
produce all kinds of high purity targets with full density and homogeneous texture,which will ensure a high utilization rate and greater efficiency
provide all kinds of tungsten crucibles and tungsten crucibles according to customer's drawings and machines to reach high precision
