C-103 Niobium Alloy Description
The C103 alloy is a niobium based alloy that is used in aerospace applications because of its incredible heat resistance, light weight, reliability, and ability to stand up to intense heat. This is a hard metal made mostly of niobium and some other things like hafnium and titanium.
The metal has a melting point of 4260±90ºF and a density of 0.320 lbs./cubic inch. This makes it good for spacecraft and parts used in super-heated rocket engines. People often use C103 niobium alloy to make parts for scramjet engines.
Niobium alloy is available in wire, sheet, bar, tubing, rod, and powder for additive manufacturing. Please ask for other shapes. Please ask for a price quote by clicking on the link above. The price will be based on your requirements.
C-103 is successful because of its low density and high strength across a wide temperature range. It's a well-known material that can be used for rockets and space exploration.
C-103 is easy to make, unlike other refractory metals, refractory ceramics, or composites made for aerospace. Even though C-103 has a high melting point, you can use traditional techniques to make flat and round products. C-103 is easy to machine and weld without losing its strength. This makes it possible to make complicated aerospace parts easily.
C-103 is used in many parts of airplanes like thrust boosting flaps in gas turbines and high-temperature valves. Researchers are working on making alloys made of niobium for future aircraft parts like heat pipes to cool the edges and nose cones of hypersonic planes.
