The “Kroll” and “Hunter” processes are still in use today for the commercial production of titanium, although Kroll is the most commonly used method. In the Kroll process, rutile or ilmenite is heated to get liquid TiCl4 which is then purified by fractional distillation processes, like the ones used to make gasoline from crude oil.Â

In aerospace, it accounts for nearly 50% of an aircraft’s total weight and it's so valuable in the industry that it’s even sometimes referred to as “aerospace metal.” For automakers, titanium’s characteristics can create parts with better aerodynamics and performance. Its low density and high strength also make it a more cost-effective manufacturing process since less material is needed.

In 1910, Matthew A. Hunter, a scientist from New Zealand working at the Rensselaer Polytechnic Institute in New York, isolated it by heating titanium tetrachloride (TiCl4) with sodium at high pressure and temperature (1292–1472°F). The result was pure titanium, and sodium chloride as a byproduct.Â

Despite raving about all of titanium’s perks, it’s worth having a look at a few things this metal is not so good at. For starters, it can be reactive at high temperatures of over 700°F—something that makes the fabrication rather tedious and highly controlled. Production of titanium has to be in a carefully controlled and oxygen-free environment.Â

He wasn’t the only one to stumble across this valuable metal and wonder what it was; Franz-Joseph Müller von Reichenstein, a mineralogist and mining engineer in Austria, was in a similar predicament. In 1795, a Prussian chemist, Martin Heinrich Klaproth, also happened upon this super strong element. He was the one who named it “titanium” — after the Titans of Greek mythology. It would take another 115 years until anyone managed to get pure titanium out.Â

Titanium is Earth’s ninth most abundant element and can be found in igneous and sedimentary rocks, minerals, clay, and sand. However, you won’t be able to find titanium in its pure form in nature as it tends to react with oxygen. When it does, it creates a titanium dioxide (TiO₂) protective layer. Titanium is mainly extracted from two minerals—a dark brown to black rock with a crystal-like appearance called rutile, and ilmenite (titanium-iron oxide), a grayish-black rock. Other minerals that can also be refined to get pure titanium are anatase, perovskite, brookite, and titanite.

Is titaniuma metal

While its low thermal conductivity does have its benefits, it can lead to the heat generated during manufacturing to build up in the tool rather than the material—not great news for the tool’s lifespan and quality. In addition, at temperatures above 570°F, titanium has low creep resistance (the slow deformation of a material when constantly under heavy loads). Finally, refining raw rocks and minerals to get pure titanium is not a cheap, easy, or quick endeavor.

The beta class includes titanium alloys that are stabilized with elements like vanadium or molybdenum. These, too, are corrosion-resistant, workable, and have a high strength-to-weight ratio. They also have better ductility and formability than alphas.Â

Whatis titaniumused for

Titanium was first discovered as a mineral inclusion in 1791 in Cornwall, South West England, by a clergyman, geologist, and chemist called William Gregor. While out by a stream, Gregor found some black sand that was being pulled by a magnet. Upon closer inspection, he found iron oxide, and another whiter metal oxide that he didn’t recognize. He named the metal “manaccanite” and reported his discovery in French and German science journals.Â

The list below describes the titanium classes and the grades that fall under them, along with their composition, features, and applications.

Is titanium hardreddit

Then, in 1932, William Justin Kroll, a metallurgist from Luxembourg, found another way to isolate titanium, this time by reducing TiCl4 through fractional distillation with calcium, and later with magnesium and sodium. In the 1950s, the Soviet Union started using titanium for its military applications, including aviation and submarines, and it wasn’t long before the USA and other countries hopped on the titanium bandwagon.

Titanium is used in everything from condensers in power plants and desalination plants to consumer goods like golf clubs and bicycle frames. Our aerospace and automotive customers heavily rely on titanium, as it often finds itself useful in their projects.Â

Molten magnesium is then added to the liquid TiCl4 which results in a porous, titanium “sponge” and a magnesium-based salt. After that, this sponge is compressed and melted in an arc furnace, and the pure titanium is cast into ingots. To make alloys, the pure titanium melt is mixed with other metals before the ingots step.

These alloys combine features of both alpha and beta types. They’re strong, ductile, corrosion resistant, and can withstand high temperatures. Of these, Xometry regularly provides quotes on CNC or sheet cut parts made of Grade 5 titanium.

There are three classes of titanium—alpha-alloys, beta-alloys, and alpha-beta alloys—and various titanium-alloy grades that fall under these classes. Although there are around fifty different titanium alloy grades, ASTM International recognizes only 31 titanium metal and alloys in total, only four of which are actually pure. Each alloy type has different properties that make it more suitable for particular applications.Â

Titanium has quite the reputation for being one of the strongest metals around. This “wonder metal” (yes, it also goes by that moniker) is used for many different applications in various industries, and it comes in different grades and alloys. At Xometry, we can instantly quote parts CNC machined or sheet cut titanium. Let’s learn more about titanium, how it’s made, and what it can do.

This class covers pure titanium and titanium alloys that are stabilized with elements like aluminum. They are super strong and ductile (although less so than other classes), formable, lightweight, corrosion resistant, and have high-temperature stability. Of the alpha class, Xometry offers Grade 2 titanium parts via CNC machining or sheet cutting.

We’ve already covered the titanium grades most commonly used in different industries above (such as industrial, chemical processing, and marine), but here are a few more ways titanium is widely being used around the world today.Â

Is titaniumstronger than steel

Titanium is one of the strongest metals on the periodic table. It’s highly durable with a long expected life, thanks to its high tensile yield strength, hardness, and fatigue resistance. It’s versatile enough to be fabricated with many different machining methods, including forming, rolling, casting, and welding.Â

Is titaniumharder than stainless steel

Grade 5 (Ti 6Al-4V) titanium is the one used for 3D printing. Grade 5 is best for 3D printing because of its high strength, excellent formability, and thermal stability. Powder bed fusion 3D printing methods like selective laser melting, electron beam melting, and direct metal laser sintering are used to 3D print titanium. These processes consist of selectively melting titanium powder that has been precisely laid onto a print bed. A powerful laser or electron beam melts the titanium powder and fuses it with the preceding layers of printed material to build completed parts.

Titanium is a metal that’s mainly known for its high strength, low weight, and corrosion resistance. It has the atomic number 22, and its chemical symbol on the periodic table is “Ti.” It has a silvery hue that typically leans toward either gray or white, but it can turn almost any color on the spectrum with different titanium anodizing methods by controlling the voltage during the process. Like most metals, titanium also has a shiny surface.

Although titanium doesn’t rank as one of the most expensive metals in the world, it is pricier than other common metals used in industry, like steel or aluminum. Pure titanium costs around $18 to $20 per kilo, and titanium alloys are usually priced anywhere from $70 to $80 per kilo.

It won’t expand or contract as much as other materials (i.e., steel) in high temperatures, and it’s also bulletproof against handguns and hunting guns (although it will understandably struggle with high-powered, armor-piercing, military-grade weapons).

Its lower density (compared to many other metals) makes it impressively lightweight, and it has a high strength-to-weight ratio, too—more than aluminum, and it gives steel a run for its money. A titanium structure weighs around 45% less than a corresponding steel one as it has a lower density.Â
