The aluminum titanate has higher melting point,lower thermal expansion coefficient 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. The aluminum titanate riser tube is the key part of the low pressure aluminum casting machine,the features are as following: 1,Excellent thermal shock resistance 2,No infiltration with the non-ferrous metal 3,Excellent wear resistance 4,Low thermal-expansion coefficient 5,The service life of the aluminum titanate riser tube can reach 60 days , can enhance the production efficiency and reduce the cost. 6,Isostatic Forming 7,Exact dimensions machined by CNC
