Our product is designed for smelting or casting of molten aluminum, aluminium alloys, magnesium alloys, zinc and copper alloys.

 

A. High density, high mechanical strength;

b. Excellent thermal conductivity, low thermal expansion;

c. High washing resistance, oxidation resistance, acid resistance and thermal shock resistance;

d. Low wettability with the melts, bring minimum impurities to the melts;

e. High cost performance, long service life.

 

Also we can supply Si3N4 (SSN, RBSN, G. P.S-SN, HPSN), O’ -SiAlON tubes. Please contact us if interested.
