Tungsten
Tungsten (W, 74 in the periodic table of chemical elements) is a steel-gray transition metal known for its high density and melting point. In its pure form, tungsten is a hard and brittle material with exceptional mechanical and thermal properties. Tungsten has a melting point of 3,422 °C, making it the most heat-resistant metal. This […]
Tantalum
Tantalum (Tantalum, Ta, in the periodic system of chemical elements 73) is a white-silver transition metal covered with a bluish oxide film, moderately shiny. It has a relatively high melting point (3017 °C), and is comparable in plasticity to gold. It lends itself well to processing, rolled into sheets, drawn into a thin wire, capable […]
Rhenium
Rhenium (Rhenium, Re, in the periodic system of chemical elements 75) is a silvery transition metal. Shiny, in powder form is black. It belongs to the champions in terms of hardness and density. One of the important qualities of rhenium is the ability to maintain strength even after repeated cycles of heating (up to 2,000 […]
Zirconium
Zirconium (Zirconium, Zr, in the periodic system of chemical elements 40) is a gray-silver transition metal with a pronounced luster. It is characterized by high ductility, excellent processing at any temperature, resistant to corrosion. This metal in its pure form melts at 1845°C, and in the form of dioxide (ZrO2) at 2680°C. Thanks to this […]
Niobium
Niobium (Niobium, Nb, in the periodic system of chemical elements 41) is a gray-silver transition metal, has a pronounced luster, is covered with an oxide film during oxidation. The areas of application of this metal are due to its valuable qualities: • it is resistant to corrosion; • lends itself well to welding, processing by […]
Hafnium
Hafnium (Hafnium, Hf, in the periodic system of chemical elements 72) is a silvery transition metal, shiny, in the powder state it acquires a dark color and dullness. Valued for: • refractoriness (melts at 2233 °C); • hardness; • resistance to acids; • the ability to significantly strengthen alloys (for example, adding 1% of this […]
Vanadium
Vanadium (Vanadium, V, in the periodic system of chemical elements 23) is a gray-silver transition metal, covered with a multi-colored oxide film in air. This metal is valued for its lightness (almost 1.5 times lighter than iron), excellent ductility, and the ability to improve significant properties of alloys – strength, impact strength, and wear resistance.
