Production and supply of aluminum casting nozzle material

Cast aluminum nozzle material is my company to develop and produce the ceramic composite product, made of ceramic fibers and inorganic ceramic materials science, having a moderate elasticity, small deformation amount, long life and other advantages. Can effectively prevent the molten aluminum for casting nozzle cavity erosion, so as to provide an effective guarantee quality aluminum casting. We can produce a variety of models and for streamed casting nozzle according to customer requirements. Casting Tip cuisine indicators density (kg / m3) the highest temperature expansion coefficient (0-1000 ℃) Thermal conductivity (900w / mk) shrinkage factor (700 ℃ × 12h) Compressive strength (MPa) 1 # 390-430 ≥1000 ℃ 2.5 × 10-6 ≤0.12 ≤0.5 ≥0.10 2 # 450-490 ≥1200 ℃ 2.1 × 10-6 ≤0.14 ≤0.5 ≥0.15
