Our 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.
