Ranking of hardness of various metals: tungsten, titanium, tritium, osmium, iron, steel, zirconium, chromium, vanadium, tantalum. These metals have very high hardness and are also very rare. These metals can be used in daily life and industry and are indispensable metals in daily life and industry.
Metal hardness ranking:
Tungsten is one of the ten hardest metals in the world. This substance is a rare metal found on the earth and is a naturally occurring metal. It had been discovered at this time in 1781 and became a new element. This metal has a very high ignition point and a very high boiling point, but a very important point is that it contains a certain amount of toxins.
Tungsten is one of the hardest metals in nature, and it is also the natural metal with the highest tensile strength. It has a high density (19.25 grams per cubic centimeter) and a high melting point (3422°C). The high melting point of tungsten makes it an ideal material for Good material for applications such as rocket nozzles. However, tungsten is brittle and easily damaged upon impact, similar to ceramics, but the brittleness of high-purity tungsten will be improved.
Applications: Tungsten is used in the steel industry to make wear-resistant alloy steel and is also used in lighting equipment, aerospace and chemical industries.
Titanium is glossy and silver-like. It has a very low density but is very strong. It is not afraid of seawater corrosion and is generally used in industrial production. This metal is also friendly, so it can be used for human use.
Titanium is known for its strength. Although it doesn't compare to any other metal in terms of Brinell hardness, titanium has an impressive strength-to-weight ratio, almost two times that of steel, and even pure titanium is harder than many sheets of steel, so titanium and Its alloys (for example, alloys with iron and carbon, aluminum and titanium alloys) are usually used in aerospace engineering for spacecraft panels, fuel tanks, and jet engine parts. It is also widely used in shipbuilding, pipeline construction in corrosive environments and as a framing material.
Titanium is non-toxic even in big doses and does not play any natural role inside the human body. It is biocompatible, so it has many medical uses.
Tritium is also a newly discovered metal and is very rare. It is mainly from the United States, China, Sri Lanka, and other regions. This metal is difficult to separate from other elements and has a certain degree of polymerization.
Osmium is the highest-density metal and is also very rare. Its surface has a certain gloss and will not be changed by water or acid. It is often used as a catalyst and is also used in industrial production.
Osmium, a platinum group metal, is the densest natural element on Earth (22.59 grams per cubic centimeter). Resistant to high temperatures (melting point over 3033°C), often alloyed with other platinum group metals (such as iridium, platinum, and palla dium), used in many different areas where hardness and durability are required.
Iron is the most abundant of all metals, very common in life, and relatively cheap compared to other metals. Very versatile. Whether it is food, containers, or even cars, iron is used.
Steel is boardly used in industrial production because of its very good hardness and certain toughness. It is mainly used for ship tools, machine weapons, etc. Steel occupies a relatively important position in building materials and also occupies a certain position in human life.
Steel, strictly speaking, is an alloy rather than a separate metal. It is an alloy metal made of iron and other elements like carbon, chromium, nickel, manganese, etc. It is the most used material in construction, mechanical engineering and other industries. Because steel is available in many different quality grades, there is no universal hardness value. In order to improve the wear resistance and heat resistance of steel, there are many different tempering techniques. Boron coatings, for example, can optimize the hardness of steel without making it brittle.
Zirconium is a transition metal with a silver-gray surface and strong corrosion resistance. It is often used to make items such as pipes and pipe fittings, as well as steel alloys, bricks, ceramics, etc.
Chromium itself has a strong luster, but it is very brittle, and the surface is also silver-gray. It has a certain degree of polish and will not fade when combined with air. But if it is in oxygen, there will be great instability.
Chromium, the hardest metal known, is often used to make alloys such as stainless steel. It ranks among the best on the Mohs scale, which measures scratch resistance. Chromium is valued not only for its hardness but also for its high corrosion resistance. Since chromium is easier to process and more abundant than platinum group metals, chromium is a commonly used element in alloys.
Chromium also has a very high hardness on the Mohs scale (8.5 out of 10 for diamond), which means it can scratch samples of quartz and topaz but can be scratched by corundum.
Chromium is also highly valued as a metal that can be highly polished without tarnishing. Polished chrome reflects nearly 70% of the visible spectrum and nearly 90% of infrared light is reflected.
Vanadium has a certain softness, is very rare, and is very tough. The surface is gray-white and is mostly used to make engines, bearings, and gear lights. It can also be used as an auxiliary element in medicines. Its origins are in South Africa and Russia.
10. Tantalum
Tantalum has an oxide film on its surface and is widely used in industry. It is often used to make engines, capacitors, etc.
