LIFE
The alloy selected by Columbus
NIOBIUM is a special steel with manganese,chrome,nickel,molybdenum and niobium.Columbus's special chemical composition,the combined effect of
strengthening for precipitation and reducing the alloy grain size are incredibly enhanced compared to standard steels. Niobium proves more effective than
Vanadium as an alloy-strengthening agent. After specific processes of progressive drawing and forming, NIOBIUM undergoes a special heat treatment that gives the
steel its final characteristics. It is a steel designed to provide superior mechanical characteristics and higher resistance to environmental effects than conventional
carbon steels.The only serious choice for a competition or top-of-the-line frame, where lightweight and reliability are essential.
Mechanical characteristics: Rm =1000 1150 MPa,Rp0.2 =750 MPa,Ap5 >14%.Material suggested for TIG welding:OK TIGROD 13.12 (AWS 5.28 ER 30S-G).MIG:OK AUTROD 13.12 (AWS 5.28 ER 30S-G)
The characteristics of the Life tubes
Small thickness, down to 0.45 mm. Availability of over size tubes for the TQ ((42)and the TV (35). Main triangle in NIOBIUM and rear stays in alloyed steel.
Excellent resistance/weight ratio. Exceptional mechanical characteristics: high breaking load, superior tenacity and incredible fatigue endurance
Reasons to choose Life
