ZhengZhou STA aluminium titanate riser tube stalk for die casting

The aluminum titanate has higher melting point (1860 C), 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.
