Product Details

STA High temperature silicon carbide crucibles for melting aluminum & copper

1. Shape: According to your drawing.

2. Material: graphite+SiC

3. Process:mold Isostatic pressing

4. Application: for melting iron, aluminum and alloys

1.Thermal stability: We make special design to assure the quality accordig to the instant temperature changing working condition.

2.Corrosion resistance: Precise design extends the ability of corrision resistance of the crucible.

3.Impulsion resistance: Duratight graphite crucible can stand very strong heat impulsion, so it can be freely used in any technic process.

4.Acid resistance: Impregnation of special stuff can improve the quality of the crucible and its outstand in the acid resistance. As a result, it can prolong the work life of the graphite crucible.

5.Fine thermal conductivity: High content of fixed carbon ensures the good thermal conductivity, shorten the dissolving time and lower the cost of the oil and other energy obviously.

6.Control of metallic pollution : Strict control of the contents assures that there is no pollution to the metal during dissolving.

7.Quality stability: High-pressure manufacturing method and quality control system can pledge the quality stability better.
