Materials

International Syalons manufacture a family of silicon nitride based sialon alloys developed for a wide variety of industrial applications. In addition, we also offer yttria stabilised zirconia, which compliments our range of sialons in many applications.

Syalon 101

Syalon 101 is a grade of sialon which offers the best general combination of properties. These include high strength, hardness and toughness as well as excellent corrosion resistance. It can be used in applications approaching 1200°C in air. Typical applications of Syalon 101 include thermocouple protection sheaths, milling media and hydrocyclones.
Syalon 050

Syalon 050 is suited to wear and high temperature applications. It has extreme hardness combined with high strength and can be used in applications upto 1400°C in air. Typical applications of Syalon 050 include shot blast nozzles and thermocouple protection sheaths for high temperture alloys.
Syalon 501

Syalon 501 is a composite grade of sialon developed to produce an electrically conducting ceramic. This allows Syalon 501 to be electro-discharge machined into complex shapes. The mechanical and wear properties of Syalon 501 are excellent and it can be used upto around 800°C in air. Typical applications include extrusion dies and molten metal level sensors.
Syalon 110

Syalon 110 is a composite grade of sialon originally developed as a break ring for the horizontal continuous casting of steel. As such it's properties include improved corrosion resistance to steel over other Syalons, outstanding thermal shock resistance and usable upto temperatures in excess of 1450°C.
Zircalon

Zircalon is an yttria stabilised zirconia ceramic and is the toughest of all monolith ceramics. It is available in two grades, Zircalon 5 and Zircalon 10 and is characterised by very high strength and toughness giving it excellent wear resistance as well as excellent corrosion resistance. Zircalon is used in applications such as weld location pins.
