Audited Supplier Description of niobium C-103 alloy bar/ingot
The niobium C-103 alloy bar/ingot consists of C-103 niobium alloy, a complex refractory metal alloy consisting of niobium, hafnium, titanium, and other alloyed elements. C-103 niobium alloy is a widely used material with excellent mechanical strength and stability.
Application of niobium C-103 alloy bar/ingot
Niobium C-103 alloy rods/ingots are widely used in aerospace applications due to their incredible heat resistance, light weight, competitive pricing, reliability, and ability to withstand intense vibration and low temperatures. With a melting point of 4260±90ºF and a density of 0.320 lb/cubic inch, C-103 niobium alloy is ideal for use in space, as well as components used in superheated thrusters and rocket engines. C-103 niobium alloy is widely used in the manufacture of scramjet components.
Niobium C-103 alloy rod/ingot filler
Our niobium C-103 alloy rods/ingots are clearly labeled and labeled on the outside to ensure effective identification and quality control. Great care is taken to avoid any damage that may be caused during storage or transportation.
Niobium - zirconium alloy superconducting material
(Superconducting material of Nb-Zr alloy system)
Nb zirconium wire is the earliest practical superconducting wire, the composition range is 15%-50% Zr, 25%-35% Zr Jc is the best, 65%-75% Zr Hc2 is the highest, the typical composition is 25% Zr and 33% Zr, the density of 7.2 ~ 7.7 g/cm2. The basic process of wire preparation is as follows:
Niobium + zirconium --> Vacuum melting casting --> 1200ºC hot forging --> Rod making --> Drawing --> Heat treatment --> Copper plating
The hardness of niobium - zirconium alloy is high and difficult to process. It is easy to stick the mold when drawing, so it is necessary to set the stainless steel tube. The wire diameter is 0.025 ~ 0.51 mm. Jc increases with the increase of cold working degree. At 600 ~ 700ºC, phase transformation occurs and Jc can be increased by an order of magnitude. High temperature phase is formed when heat treatment is above 750ºC, and Jc decreases obviously.
1--Nb-25Zr(supercon, cold drawn); 2 -- 600ºC, heating for 4min; Heat at 3-600 ºC for 64min
FIG. 1 and FIG. 2 respectively show the H-Ic characteristics of Nb-25Zr and the Jc-H curves at different temperatures. Cold rolled strip has obvious anisotropy. For example, 10% ~ 30% Zr alloy, when the external magnetic field increases from zero to 2.35 T, Jc// along the rolling direction decreased 1.5 ~ 2 times, and Jc perp in the vertical rolling direction decreased 20 ~ 30 times. The Jc//+Jc perp of 96% cold deformation sample can be larger than 20 ~ 30. Jc//=(4 ~ 5)×103A/mm2 and Jc perp = 2.5 ×103A/mm2 on the cold deformed Nb-25Zr line after heat treatment at 600ºC for 100h at 2.35 T
Niobium-titanium has replaced niobium-zirconium superconducting materials due to its good combination with copper, ease of processing, and higher Hc2 and Jc.
