What is c103 material?

C-103 Nb alloy is a complex refractory metal alloy consisting of niobium (Nb) with additions of 10wt% Hf (hafnium) and 1wt% Ti (titanium). C-103 Nb alloys are among the leading refractory metals used in propulsion and space exploration technologies.

Is niobium very reactive?

Apart from reacting with oxygen in air at high temperatures, niobium is reactive to carbon, nitrogen, sulfur and halogens. Niobium is non-reactive to acids and moisture at room temperatures but reacts with acids at elevated temperatures.

What is columbium used for?

Columbium is an important alloy in high-strength, low-alloy (HSLA) steels. High-purity columbium products are used in superalloys for the AEROSPACE INDUSTRY and in superconductor magnets for powerful generators.

Why is niobium added to steel?

Niobium added to steel refines remarkably the cast structure and austenite structure of steel. An adequate and yet minimum quantity of niobium necessary for the refining control of austenite–grains in steel is 0.03 to 004%. With an addition of niobium, the coarsening temperature of austenite-grains will rise.

What is C103 copper?

Description. C103 (Cu-OF) is a commercially pure grade of oxygen-free copper manufactured by pouring in a protective gas atmosphere or vacuum. The absence of oxygen ensures high levels of electrical conductivity and low susceptibility to embrittlement when heated in a reducing atmosphere.

Is niobium an alloy?

The most common commercial niobium alloys are ferroniobium and nickel-niobium, produced by thermite reduction of appropriate mixtures of the oxides; these are not usable as engineering materials, but are used as convenient sources of niobium for specialist steels and nickel-based superalloys.

Is niobium toxic?

Health effects of niobium Niobium and its compounds may be toxic (niobium dust causes eye and skin irritation) , but there are no reports of human being poisoned by it. In laboratory animals, inhalation of niobium nitride and/or pentoxide leads to scarring of the lungs at exposure levels of 40 mg/m3.

Are columbium and niobium the same thing?

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950.

How do you extract niobium?

Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining. Niobium powders can be produced by the reduction of potassium niobium heptafluoride (K2NbF7) with sodium, or by the reduction of niobium oxide with magnesium.

What is C-103 niobium alloy?

C-103 Niobium Alloy is a niobium-hafnium-titanium) is a high-performance, heat-resistant alloy typically used in aerospace components and other high temperature environments. American Elements’ niobium C-103 meets ASTM B652, B653, B654, AMS7852 and AMS7857 grades and is available in standard and custom forms such as wire, sheet]

What is the melting point of niobium?

The alloy has a melting point of 4260 ± 90ºF, and a density of 0.320 lbs./cubic inch, making it ideal for use in space, as well as for components used within super-heated thrusters, and rocket engines. The C103 Niobium Alloy is widely employed in the manufacturing of scramjet engine components.

What is ctc103 alloy?

C103 Alloy is a Niobium based alloy that is widely used in aerospace applications because of its incredible heat resistance, as well as its light-weight, cost, reliability, and ability to stand up to intense vibrations and cryogenic temperatures.

What is niniobium C-103 heat treatment?
