What is C-103 Nb Alloy?
C-103 Nb is an alloy comprised of carefully controlled amounts of niobium, hafnium, titanium, and additional alloying elements. Using a precise and complicated manufacturing process, we produce C-103 Nb alloys with extremely consistent microstructure resulting in exceptionally well controlled material properties.
We work closely with customers to supply a variety of C103 products including bars, rods, sheet, plate, ingot, slabs, powders, and custom fabricated parts.
C-103 Nb Alloy Properties: Fabricability, Stress Resistance & High-Strength
The primary advantage of C-103 Nb alloy is its exceptional high-temperature strength (for a relatively lightweight material) which it can maintain up to temperatures as high as 1482°C! This level of stability also extends into negative temperatures; in addition, C-103 also displays a low susceptibility to high-frequency vibrations at temperatures below -150°C. C-103 can also be made into such a variety of shapes and configurations due to its relatively high formability. In addition, it can be welded via TIG (tungsten inert gas) processes without significant loss of ductility or machinability. We target the alloy to meet or exceed ASTM/AMS specifications but are open to certain levels of customization when applications require it.

Niobium C-103 Fabrication Process
Niobium alloy C-103 has high melting point. Fabrication process involves C-103 ingots production process and mechanical process. Niobium hafnium alloy is processed into ingots by combining electron-beam cast with vacuum consumable electrode arc furnace. Then C-103 is extruded or forged over 1200℃. After rolling and drawing under 500℃, niobium hafnium alloy C-103 is manufactured into sheets, strips, rods, wire or other fittings.
Specifications
C-103 niobium alloy meets ASTM B652, B654, B655, AMS7852 and AMS7857 specifications.
