Blue Demon ERAZ61A Magnesium TIG Rod

ERAZ61A magnesium welding alloy is generally the preferred filler metal when welding magnesium base metals of similar chemical composition as well as ZK21A.  It produces strong joints with high tensile strength.  Cleanliness of both the filler metal and base metal is extremely important when welding with magnesium.  Flux is NOT required for TIG or MIG welding processes of ERAZ61A magnesium alloy. Although Oxy-acetylene welding of this alloy is uncommon it can be done and should be limited to single-pass welding on thin gauge magnesium materials.
