Product Overview
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. Available Size & Types: ID max: I 220 mm; Length max: 1700 mm; Metal flange type or one body type. Applications: Low pressure die casting and counter pressure die casting of molten aluminum, aluminum alloys, magnesium alloys and copper alloys. Typical chemical analysis: SiC: > 70.00%; Si3N4: >20.00%; Free-Si: < 0.20%; Fe2O3: < 0.15%. Typical Technical Data: Porosity: < 11%; Bulk Density: > 2.65 g/cm3; Compressive Strength: > 175 MPa; Flexural Strength: > 70 MPa; Thermal Conductivity (1400 A C): > 16.5 A 10-6 W/ (mA C); Thermal Expansion (20-1400 A C): < 4.6 A 10-6/ A C; Maximum Working Temperature: 1550 A C.
