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.
