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.
