The niobium has a very high melting temperature and is not damaged by acids at room temperature.
It has a layer of oxide and is similar to tantalum. However, it has a much lower density.
Tantalum is one of the metals of high melting point, is very resistant to acids (except hydrofluoric acid). It is very hard, elastic and well deformable. It's a weldable metal.
Industrial applications: Electrical and chemical engineering, in the construction of high temperature furnaces, in evaporation plants, in nuclear technology.
Titanium is a chemical element (Ti)
It is lightweight, strong, elastic, metallic white shiny and corrosion resistant. It is particularly suitable for applications where high corrosion resistance, strength and low weight are required. It belongs to transition metals.
Tungsten silver (AgW) is one of the composite metals of silver.
Its composition ranges from 50-85% W (tungsten), with the balance of Ag (silver) as low voltage contact material for switching under the air, also used as electrode material. See other composites by clicking to learn more.
Nickel alloys 601 (2.4851 / US N06601)
A nickel-chromium alloy with aluminum addition for excellent oxidation resistance and other forms of corrosion at high temperature. Good mechanical properties at elevated temperatures. Use for industrial furnaces, heat treatment equipment such as baskets, muffle and retorts, for petrochemical equipment and other process equipment and for gas turbine parts.
Tungsten is unbeatable when it comes to heat resistance. Tungsten has the highest melting point of all metals and possesses after the carbon element at 3422 ° C the second highest melting point of all the chemical elements. Tungsten is generally used for: switching electrical contacts, heating conductors, shielding, erosion electrodes, welding electrodes, friction welding tools, thermocouples, tool holders, scales weights, medical technology, protection elements for ranges of radiation or X-rays.
Molybdenum (Mo 99.95%) is used where high temperatures are generated, such as high temperature heating elements, shielding, incandescent filaments, evaporator crucibles, rocket drives, radiation shields, thermal protection tubes, X-rays, welding electrodes, thermodes, sliding coatings, components and heating rods in glassmaking, spray targets and the like. Molybdenum has a high thermal conductivity and versatility. Molybdenum rods are produced by our metallurgical industry.
The application of Rhenium is limited due to its availability. It is mainly used in small quantities to provide substantial benefits as an alloy additive: rhenium is a component with heat resistant superalloys.
Nickel-based superalloys are often used in jet engines where they are prized for their high strength.
Rhenium containing alloys can also be used in crucibles, self-cleaning electric contacts, electromagnets, ionization meters and spectrographs.
This compound spontaneously forms when the pure osmium is in contact with air, and is both volatile and extremely toxic, therefore pure metal is rarely used. The osmium is the most densely occurring natural element and confers hardness when used in metal alloys. The alloys containing the osmium are hard and are used in many contexts, especially where there is resistance to wear caused by friction when there is frequent operation.
Ruthenium is notable for being a hard and corrosion resistant metal.
It is a harder metal than platinum and palladium, and like rhodium, can be used to toughen the alloys of these elements. Fine coatings of platinum-ruthenium and palladium-ruthenium alloys are often used to make wear-resistant electrical contacts.
In addition, ruthenium is added to titanium to provide corrosion resistance.
It is also used in high temperature single crystal superalloys, mostly used in aerospace applications.
Iridium is the most corrosion resistant metal of all metals, is extremely hard and has an extremely high melt temperature of 2466 degrees Celsius. Although resistance to iridium metal change is extremely desirable for some applications, the disadvantage is that solid iridium is too hard and brittle to work or to machine and melt to a very high temperature to make traditional casting practical.
Rhodium is a hard, durable metal with a shiny silver appearance and high corrosion resistance. It is one of the rarest metals in the earth's crust.
Rhodium-based catalysts are widely used in industrial processes and other applications of organic chemistry.
Rhodium is used as an alloying agent that improves corrosion resistance and increases the hardness of platinum and palladium.
Rhodium-containing alloys are used in spark plugs, advanced laboratory equipment and in thermocouples.
In jewelry making, they are galvanized in white gold or platinum, extremely thin layers of the precious metal to give a reflective white surface, this is a process known as "intermittent rhodium".
Palladium is similar to other elements of the platinum group, it is a silver metal that is relatively non-reactive, but of the group has the lowest melting point and is the least dense. In its applications it is more similar to platinum: useful in the metallic form for the production of a variety of products and as a catalyst.
Palladium catalyzes reactions involved in oil breakdown, water treatment, nitric acid production and polymer fabrication, and is found in catalytic converters and fuel cells as a catalyst.
It is also used to increase the rate of hydrogenation and dehydrogenation reactions, and serves many catalytic functions specialized in organic chemistry.
Platinum is, in a way, the best metal for jewelry rather than silver or gold, which does not stain like silver.
Since several jewelers began to use the metal in the late 1800s, platinum quickly grew in popularity, becoming particularly fashionable for the establishment of colorless stones, which lasted until 1940, when platinum use was restricted to industrial production of chemicals needed to strengthen the war. Platinum has been replaced by white gold because of these restrictions, but has returned to be popular in recent years.
Platinum alloys are used in a wide range of configurations where chemical inertia or wear resistance are important, including medical devices, laboratory instruments, electrical contacts, spark plugs and turbine engines.
Pure metallic gold has remarkable properties because it is the most malleable and ductile of the metals and with an unusual color in keeping with the elements of its class. It is mainly non-reactive, conducts good electricity and is extremely dense. The density of gold helped to drive its relative rarity, for when the Earth was formed the gold would have sunk to a large extent in the center of the planet. According to science, virtually all gold discovered by humans was deposited considerably later by meteorites that contained the element.
The rarity of gold is explained by its combination of the ease with which it can be worked, the visual distinction and the resistance to chemical corrosion, which makes it an extremely unusual material and object of much fascination.
