Selected Applications of Sialons

Owing to their mechanically strong, hard, and tough properties, the sialons find application in fields where high-temperature strength and corrosion resistance are required, including  

Metal wire and tube drawing tools Wear components 

Location pins for resistance welding of automotive components Seals and bearings 

Metal melt feeder tubes for die casting of non-ferrous metals Heater tubes Burner nozzles 

Whilst, in the past only P-sialon was utilized, today a/P-sialons with improved hardness are increasingly appUed for modem cutting tools in the high-speed machining of cast-iron or hard superaUoys. Sialons retain strengths to substantially higher temperatures compared to either cemented carbide or white and black
