Joining of plain carbon steel (SS41) to alumina or mullite using copper filler metal was made in a slightly oxidizing atmosphere. Joining strength was determined by fracture shear loading. The liquid copper wetted both alumina and steel during joining, and a strong joining was formed after cooling down. The strong bond is attributable to the formation of hercynite (FeAl2O4) at the interface between copper and α-alumina. The use of this joining provides various type of joints such as alumina/steel tee joint and alumina butt joint strapped with steel.
