Nitride Bonded Silicon Carbide Stalk (Riser) Tube

Our Nitride Bonded Silicon Carbide Stalk (riser) Tube is designed for die casting of molten aluminum, aluminium alloys, magnesium alloys and copper alloys. As replacement of cast iron and old ceramic ones.
Also we can supply stalk (riser) tubes made of other materials or by different process, for example, Si3N4 (SSN, RBSN, G.P.S-SN, HPSN), Oa -SiAlON, aluminum titanate, dense fused silica and coated cast iron. Please contact us if interested.
