Properties: Tungsten is one of the important alloy elements which are used to make special steel. While tungsten reduce a little elongation rate of steel, Ferro-tungsten raises strength limit and yield point and also raises hardness and abrasion resistance of steel.Ferro-tungsten is very important that tungsten has good influence on high temperature mechanical properties of steel to improve heat resistance and tempering stability of steel.Chemical Compositions(GB/T3648-1996)BrandChemical Compositions (%)WCPSSiMnCuAsBiPbSbSn≤FeW80-A75.0-85.00.100.030.060.50.250.100.060.050.050.050.06FeW80-B75.0-85.00.300.040.070.70.350.120.08--0.050.08FeW80-C75.0-85.00.400.050.080.70.500.150.10--0.050.08FeW70≥70.00.800.060.101.00.600.180.10--0.050.10Notes: Ferro-tungsten should be delivered in lump whose size range is from 10 to 130mm. the amount of debris whose size is less than 10mm×10mm should not exceed 5% of the total mass of this batch of products.

Rhenium is a silvery metal but rarely seen as such on account of its high melting point, which is the third highest after carbon and tungsten.Resistant to heat, corrosion and thermal shock, and possessing excellent electrical resistivity, rhenium is the ideal material for both project and production applications. Rhenium provides excellent wear resistance, which means increased reliability and greater dependability.Re: 99.95% minSpecifications: 1) Palladium: ≥99.95% ; 2) Platinum: ≥99.95% ;3) Rhodium: ≥99.95% ; 4) Iridium: ≥99.95% ;5) Samarium: ≥99.95% ; 6) Osmium: ≥99.95% ;7) Rhenium: ≥99.99% ; 8) Hafnium: ≥99.95% ;9) Palladous chloride, iridium chloride, etcRhenium propertiesDensity, g/cm321.04Melting Point, Celsius3180Thermal Conductivity, w/M at 20° C39.6Linear Coefficient of Thermal Expansion, m/m-K from20-1000° C6.8Ductile Brittle Transition Temperature (DBBT), °CDOES NOT EXISTElectrical Resistivity, W m at 20° C0.193Elastic Modulus in Tension, GPa460ApplicationsRhenium is used as an important component in superalloys for blades in turbine engines and this is the major use today. Rhenium is an ideal metal for use at very high temperatures, which makes it suitable for rockets motors. Rhenium is added to tungsten and molybdnum to form alloys that are used as filaments for ovens and lamps. It is also used in thermocouples which can measure temperatures above 2000 C, and for electrical contacts which stand up well to electric arcs.Rhenium, alloyed with platinum, was used in petroleum-reforming catalysis in the production of high-octane hydrocarbons, used for lead free gasoline.Other applications are rhenium-tungsten alloys in X-raytubes and rotating X-ray anodes. Rhenium-molybdenum alloys are superconductors at a temperature of 10K. Rhenium has occasionally been used for plating jewerly.
