NSIC Riser tubes is made from Si3n4 (silicon nitride) bonded SiC ceramic, used for metal metallurgy, low pressure die casting industry,especially for auto Aluminum Alloy Parts,good performance on resistance-corrosion of metal smelting, like AL, Pb, Sn, Zn metal Industry, no Fe increasing and longer life.

N-SIC ceramic stalk feature as follow:

1) Resistance of Smelting metal corrosion;

2) Good resistance of thermal shock;

3) No Creep under high temperature;

4) Resist of Acid,Alkaline, oxidization;

5) Longer life with good price.
