Heat-resistant and anti-corrosion aluminum titanate ceramic sprue bush for aluminum casting

Product Detail

Aluminum titanate sprue bush is also known as sprue cup and insulating sleeve. It is a part on the low pressure casting machine for alloy wheel and other similar casting. Sprue bushing is used between riser tube and down mould to form low pressure pouring gate.

 

Aluminium titanate sprue bushing has good corrosion resistance, strength, airtightness and thermal shock resistance.

 

Characteristic:

1.Excellent thermal shock resistance

2.No infiltration with the non-ferrous metal

3.Excellent corrosion resistance

4.Low thermal-expansion coefficient

5.The aluminum titanate lift tube can enhance the production efficiency and reduce the cost.
