Syalon 101

Syalon 101 is an advanced silicon nitride (Si3N4) ceramic offering outstanding mechanical strength, thermal shock resistance and corrosion resistant properties.

Syalon 101, a silicon nitride based advanced ceramic, is the first ofthe Si–Al–O–N family of engineering ceramic materials which has been developed, characterised and is now being manufactured under carefully controlled conditions, ensuring a high quality material is consistantly produced

Syalon 101 is a beta-sialontype ceramic and is an outstanding engineering grade material which is characterised by high strength, toughness and hardness and chemical and thermal stability. It has found use in applications demanding wear, corrosion and thermal shock resistance, where temperatures do not continuously exceed 1000°C, such asindustrial wear, non-ferrous molten metal handling and metal forming.

The table below lists typical mechanical, thermal and electrical property data for Syalon 101.

Weld Location Pins

International Syalons manufactures a comprehensive range of silicon nitride, sialon and zirconia advanced ceramic weld location and control pins. These are used in the metal forming industry to allow precise welding of nuts to sheet metal. Sialons are silicon nitride based ceramics which possess a number of characteristics, such as excellent mechanical, thermal and chemical properties, making them ideal in metal forming applications. Syalon 101 weld location pins have a proven history of success of more than 20 years by several leading automotive manufacturers.

Zircalon weld location pins are a more recent addition to our portfolio. They excel where their greater toughness is required, such as when severe impact is a possibility. Like Syalon 101 they have excellent wear resistance, however they are not recommended where thermal shock may occur. Also, they are double the weight of an equivalent Syalon 101 weld pin. Zircalon is available in two grades, Zircalon 5 and Zircalon 10. Zircalon 10 has slightly superior properties for applications which demand it.

The tables below show our range of standard weld pins. However, we make a whole range of none standard sizes, so please contact us with your enquiry.
