Composites made of carbon-based and metallic materials

摘要

The invention provides composites made from a carbon-based material and a meallic material by joining them together by means of a brazing filler metal which is an alloy comprising, as essential components thereof, at least one element selected from among vanadium, niobium, titanium, zirconium and silicon and at least one element selected from among copper, silver, nickel and aluminum as well as welding nozzles made by joining a ring made of a carbon-based material to the tip of a metal nozzle using said brazing filler metal.
