LaYZr (CHARTREUSE) EWG Principal Oxides: 1.5% Lanthanum, 0.08% Zirconium, 0.08% Yttrium Oxides This non-radioactive tungsten is best for automated or robotic uses in AC or DC, it can tolerate a low voltage and uses inverter or transformer based constant current power sources.  These tungsten's are good for low alloyed steels, non-corroding steels and alloys of aluminium, magnesium, titanium, nickel and copper. The geometry of the tips are very stable and they run cooler than the 2% Thoriated and have a longer lifespan. Use these in the low to medium amp range.  This pack of ten is the best way always to have tungsten's on hand.
