Ceriated Tungsten Electrode 2% ceriated tungsten contains a nominal 2% of cerium oxide (CeO2). Ceriated is different from thoriated as it is not a radioactive material. Ceriated tungsten also tends to last longer than thoriated and can be used proficiently with AC or DC. In manual applications, the ceriated tungsten will provide slightly different electrical characteristics than the thoriated tungsten but generally no difference will be seen by the operator. Generally used to weld carbon and stainless steel, nickel alloy and titanium.
