Aluminum Casting
Honsin Ceramics develops ceramic solutions which have outstanding characteristics in mechanical strength, high temperature resistance, wear resistance and corrosion resistance. Our products are widely used in demanding work conditions such as molten metal handling, automotive parts, valve, nozzle etc…
Honsin Silicon Carbide (SiC) and Silicon Nitride (Si3N4) components are used for high-reliability parts in high temperature and high pressure environment. We have designed and tested the solutions for a longer life use.
We have developed specially Silicon Nitride (Si3N4) material with improved thermal, mechanical and chemical properties. Honsin Cearmics is confident that our Ceramic solution for Aluminum foundry and casting can help you to produce higher quality products by minimizing contamination and to reduce operation cost, therefore, to improve your overall production efficiency and product competitiveness.
Advantages
- Longer work life
Silicon nitride is inert against molten aluminum.
it ensures longer life and requires a minimum maintenance
- Contamination free and less adhesion
Silicon nitride ceramic do not reacts with molten aluminum and will reduce greatly the contamination and adhesion.
- Light weight with high strength
Silicon nitride keeps high mechanical strength over a wide temperature range. The outstanding strength characteristics with relative low density make it easy to handle compared to conventional materials.
- Exceptional thermal shock resistance
Silicon nitride has exceptional high thermal shock resistance — making it ideal for applications with high dynamic stresses, thermal rigor, and demanding reliability requirements
