High Temperature Welding Pin Blue ZrO2 Ceramic Pins
The ceramic pins are made of hard, stabilized Zirconium oxide, Alumina ceramic or silicon nitrate, which provide longer
service life than steel pins with no risk of electrical shorting. They can work at high temperature and refactory, mainly
used for welding manchines. The extremely hard ceramic materials resist wear and spatter without any risk of localized
damage and compromising of the coating. Ceramic pins are well suited for most applications and can outlast traditional
steel pins by factors of 50 or more if used properly. Due to the high hardness and manufacturing process for the ceramic,
all parts are finished to specification by diamond grinding. This does increase the lead time and cost for each pin.
