Abstract

The herein-proposed alloy is characterized in that it contains apart from such known components as copper, tin, aluminium, cadmium, zinc, titanium, chromium, zirconium, manganese, molybdenum, tungsten, iron, cobalt and nickel also vanadium, niobium, tantalum and boron taken either separately or in combination, in an amount of 0.001 to 80 weight percent of the total weight of all the components thereof. The alloy is advantageous in possessing good technological characteristics, being resistant to oxidation at elevated temperatures, featuring good adhesion to all kinds of abrasive materials and giving strong brazing alloys and metallization coatings.
