Columbium 1% is 98.5% columbium with additions of zirconium and other elements in minor amounts. The common designation for the alloy is Cb-1Zr. Also called KBI-1
Principal Design Features | This alloy of columbium (niobium) is 98.5% columbium with additions of zirconium and other elements in minor amounts. The common designation for the alloy is Cb-1Zr. Also called KBI-1 |
---|---|
Columbium 1% Applications | Typical applications are for thermal barriers, containers for liquid metals and nuclear applications. Structural properties are good to 3000 F. However in exposure to air a protective coating is needed at temperatures above 800 F. |
Columbium 1% Machinability | This alloy is readily machined by conventional methods using high speed steel tooling. |
Columbium 1% Forming | The alloy can be formed by standard methods without difficulty. |
Columbium 1% Welding | Welding may be done using electron beam or gas tungsten-arc (GTAW) methods or resistance welding. There is a loss of ductility in the weld. |
Columbium 1% Heat Treatment | Not heat treatable for hardness. See "Annealing". |
Columbium 1% Forging | Forging may be done in the range of 1800 to 1200 F. |
Columbium 1% Hot Working | Hot working, such as extrusion, should be done at 1950 F. |
Columbium 1% Cold Working | The alloy may be cold worked with relative ease by conventional methods. |
Columbium 1% Annealing | Anneal at 1850 to 2200 F. |
Columbium 1% Aging | Not applicable. |
Columbium 1% Tempering | Not applicable. |
Columbium 1% Hardening | Hardens by cold working. |
Columbium 1% Other Comments | For use at elevated temperatures in air a protective silicide or aluminide coating should be applied to the parts made from this alloy. |
