Introduce Of Aluminium Titanate Sprue Bushing

As a unique inorganic non-metallic material with excellent thermal shock resistance and high refractory, aluminum titanate ceramics are widely used in metallurgy, thermal engineering, machinery, the chemical industry, and other fields.

Aluminum titanate sprue bushing is used in low-pressure die casting of aluminum alloy wheels or other similar castings. The sprue bushings need to be used to form part of the low-pressure runner. The product has excellent corrosion resistance, high room temperature and high-temperature strength, good air tightness, and excellent thermal shock resistance.

Advantage Of Aluminium Titanate Sprue Bushing

1. Excellent thermal shock resistance

2. Low wetting by aluminum and non-ferrous metal

3. Excellent wear resistance and corrosion resistance

4. Increasing productivity and reducing cost

5. Isostatic Forming

6. Exact dimensions machined by CNC
