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/°C
heat conductivity	0.86W/m.k

    The aluminum titanate has higher melting point(1860° C± 10° C), lower thermal expansion coefficient(RT_1000° C, α < 2.0× 10-6/° 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.
