Product Description

Sprue bush is also known as insulating sleeve. It is a part on the low pressure casting machine for alloy wheel and other similar casting. Sprue bush is used to form low pressure runner.

Aluminium titanate sprue bush has good corrosion resistance, strengh, airtightness and thermal shock resistance.

The aluminum titanate ceramic 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 is no wetting by molten metal and glass. Riser tube and sprue bushing can widely used in hard conditions of resisting high temperature, heat shock and corrosion.
