Zircalon

Zirconia (or zirconium dioxide, ZrO2) is characterized by high impact resistance and very high strength and toughness giving it excellent wear resistance. In addition it is chemically stable resulting in excellent corrosion resistance.

Zirconia is typically used in applications in the metal forming (link to our metal forming page) industry as weld location pins (link to our weld pin page)  for resistance welding of captive nuts on sheet metal.

Production Engineering offers three grades of zirconia: Zircalon 5, Zircalon 10 and Zircalon 20. The properties of these materials are outlined below.

Zircalon 5

Zircalon 5 is an yttria stabilized zirconia (YSZ) and has very good strength and toughness. The table below lists typical mechanical, thermal and electrical property data for Zircalon 5.

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.
