Aluminium Titanate Sprue Bushing

We are exporting, manufacturing & supplying Aluminium Titanate Sprue Bushing from Zibo, Shandong, Sheng, China. Aluminum titanate riser tube and sprue bushing has excellent heat-shock resistance for low pressure die casting. Advantages: 1,Excellent thermal shock resistance 2,No infiltration with the non-ferrous metal 3,Excellent wear resistance 4,Low thermal-expansion coefficient 5,Long service life Specifications: bulk density 3.3-3.5g/cm3 flexural strength 40-60MPa porosity < 8% thermal-expansion coefficient 0.5-1.5*10-6/A C heat conductivity 0.86W/m.k The aluminum titanate has higher melting point(1860A CA 10A C), lower thermal expansion coefficient(RT_1000A C, I < 2.0A 10-6/A C) and excellent heat-shock resistance. Besides, the aluminum titanate don't infiltrate with the metal melt(especially the non-ferrous metals) and glass melt. Therefore aluminum titanate can be widely used in the conditions of high-temperature resistance, heat-shock resistance and corrision resistance.
