NivacromThis is the most famous of Columbus' patented steels, specifically designed to make tubes for bicycle frames. It has the advantage over other steels of combining extremely high mechanical characteristics with great tenacity in the welding area. Alloy elements, vanadium and niobium, precipitate in the metal matrix blocking any grain growth and the resulting decline in mechanical characteristics, even at temperatures exceeding 1000C. It should be noted that, following the introduction of Nivacrom, the automobile industry began to use similar steels for producing bearing and reinforcement structures. Nivacrom though has been developed for top of the range competitive bicycle frame use.
Italian use Columbis Nivacom & Thermacom
are these materials approved by NJS?
