This blogging site provides professional knowledge of tungsten, molybdenum, tantalum, columbium to expand the markets for refractory metals. So if you want to know a bit more about refractory metals and related processed products, then please take a look through our blogs.
The high melting point, hardness and corrosion resistance of iridium and its alloys determine most of its applications. Iridium and especially iridium–platinum alloys or osmium–iridium alloys have low wear and are used, for example, for multi-ported spinnerets, through which a plastic polymer melt is extruded to form fibers, such as rayon. Osmium–iridium is used for […]
Marine engineering materials are required to have unique properties, such as high strength, resistance to seawater hydrothermal corrosion, resistance to sulfidation corrosion, antimicrobial adhesion, and high toughness. Titanium is light in weight, high in strength and resistant to corrosion. Particularly, it is immune to the erosion of saltwater or seawater and the marine atmospheric environment. […]
Powder Metallurgy Process (Video) Powder metallurgy is a process for preparing metal powders and using metal (or metal and non-metal mixture) powder as raw materials to form parts and products by molding and sintering. A brief overview of the powder metallurgy manufacturing process showing the different stages that a component part can go through from […]
Refractory metals are referred to metals with melting points over 3632°F and certain amounts of reserves, including tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium and titanium. Usually, refractory metals have great densities and weigh heavily. With refractory metal as the matrix, the alloys added with other elements are called refractory metal alloys, including tungsten […]
Special refractories mainly include high melting point oxides, high melting point non-oxides, and the derived composite compounds, cermet, high-temperature coating, high-temperature fiber, and its reinforcing materials. Among them, non-oxides with a high melting point are usually called refractory compounds, which also include carbides, nitrides, borides, silicides, and sulfides. Although the cost of special refractories is […]
Refractory metal materials mainly refer to tungsten, molybdenum, tantalum, niobium, rhenium, and vanadium, all of which are materials with a melting point above 2000 degrees Celsius. Refractory metal materials and their alloys have the characteristics of high melting point, high strength under a high-temperature environment, strong corrosion resistance to liquid metal and processing plasticity. Refractory […]
Refractory materials, such as refractory metals, alloys, compounds, and composites, have always been developed as high-tech materials due to their unique high melting point and some other unique properties and occupy an important position in the national economy. For example, cemented carbide with WC as the hard phase has become the “Tooth” of modern industry, […]
Zirconium, a rare metal, is widely used in the fields of aerospace, military industry, nuclear reaction, and atomic energy. Generally, titanium products used in spacecraft with high corrosion resistance are far inferior to zirconium, whose melting point is around 1600 degrees, while that of zirconium is above 1800 degrees, and the melting point of zirconia […]
Diamond, which is known for its hardness and wear resistance, has been used in machining for hundreds of years as a super-hard tool material. Besides, it also has the advantages of good stability and biocompatibility, which is in line with the material requirements of surgical tools used for tissue resection. Therefore, it is also very […]
As the basic material in the field of high-temperature technology, refractory materials are widely used in steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electric power, military, and other fields. With the development of technology, the preparation technology of refractories is developing into the field of fine ceramics, and some special refractories […]
