Applications of Niobium Alloys C-103 Crucibles / Cups

Niobium C-103 Alloy Crucibles / Cups are widely used in aerospace applications because of their incredible heat resistance, as well as light-weight, competitive price, reliability, and ability to stand up to intense vibrations and cryogenic temperatures. C-103 Niobium Alloy has a melting point of 4260 ± 90ºF, and a density of 0.320 lbs. /cubic inches, making it ideal for use in space, as well as for components used within super-heated thrusters, and rocket engines. The C-103 Niobium Alloy is widely employed in the manufacturing of scramjet engine components. Niobium alloy C-103 is an excellent material for liquid rocket thruster nozzles, lightweight propulsion systems and rocket engine thrust chamber in aerospace industry. Niobium alloy C-103 is also used in the manufacture of turbopump and high-temperature jet engine parts.


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.


Niobium C-103 Welding

Niobium alloy C-103 has good weldability. The welding methods include argon tungsten-arc welding and electron-beam fusion welding. Welding quality depends on the purity of argon and vacuum. The purer the argon and the lower remaining pressure is, the better the welding quality will be.


Niobium C-103 Heat Treatment

Vacuum or inert gas protection is usually applied in the process of annealing, solution and aging treatment.


Packing of Niobium Alloys C-103 Crucibles / Cups

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’ Niobium Alloys C-103 Crucibles / Cups are carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
