Niobium refractory alloys — data sheet
Niobium, also termed columbium, is a shiny grey metal that takes on a bluish tinge when exposed to air at room temperature. Due to its low-capture cross section for thermal neutrons, niobium — available from Ed Fagan — is suitable for applications in the nuclear industry. Other applications include capacitors, superconducting magnets, steel additives, reactors and optics.

Data sheet: tungsten from Ed Fagan download
This refractory alloys data sheet from Ed Fagan focuses on tungsten, which is suitable for applications including high-temperature furnace components, glass-to-metal seals, heavy-metal alloys, medical devices and welding electrodes.
Ed Fagan is offering a range of tungsten alloys. These alloys contain elements such as nickel, copper and iron. They are said to be relatively easy to machine and can be plated or painted to enhance their corrosion protection.
Nickel-iron alloys are not hardenable by heat treatment. The alloys can be made harder though cold working only. The annealed hardness for these alloys is generally in the range of RB 70/80. Material in the annealed condition will be more difficult to machine because it is soft and gummy. The tools tend to plow the metal instead of cutting into it and do not easily form chips. Surface scale oxide is tightly adherent and penetrates the surface to a greater extent than stainless steels. ...
Ed Fagan’s range of refractory alloys includes tantalum, which is resistant to corrosion by body fluids and is therefore suitable for applications such as surgical implants and instruments.
Ed Fagan offers a variety of soft magnetic alloys. This data sheet provides details of the following materials: EFI Alloy 79, EFI Alloy 50, Hiperco 50, Radiometal 4550 and Vim Var Core Iron.
