Titanium

Titanium (Ti) – Semi-Finished Products, Alloys and Custom Components Ex Stock

Titanium (chemical symbol Ti, atomic number 22) is – unlike the other special metals in the E.WAGENER range – not a heavy metal, but a silvery-white light metal with a density of only 4.50 g/cm³. Despite its low weight, titanium is considered one of the toughest and most resilient metals of all: in its pure form it is easy to form, forgeable, relatively stable under heat, and an excellent electrical conductor. At room temperature, titanium is relatively resistant to air and comparable to precious metals in its corrosion resistance.

The compound titanium dioxide (TiO₂) is well known, for example as a white pigment – however, E.WAGENER supplies the pure metal and titanium alloys as semi-finished products and components.

Titanium – Very Strong with Low Thermal Expansion

The element with atomic number 22 combines several unique properties. With a density of only 4.50 g/cm³ it is exceptionally light, yet it is considered one of the toughest and most resilient metals in the world. Knocks and impacts do not harm titanium parts.

It also has an extremely low thermal expansion. Despite its relatively high melting point (1,727 °C), pure titanium is not recommended for high-temperature applications, as physical property changes already occur between 400–600 °C and titanium begins to react with its surroundings – this can lead to ignition and even explosions.

Ultra-pure titanium is used as a getter metal to remove residual gases in vacuum technology, as it reacts with small amounts of oxygen. Corrosion-resistant, pure titanium is used in the construction of chemical plants. Due to its biocompatibility, titanium is also an established material for medical implants.

Titanium Alloys Make Almost Any Material Hard

Alloys containing titanium, on the other hand, need to be considered quite differently. Here, even the smallest amounts of titanium bring about decisive improvements in material strength. One example is the micro-alloying of steel: even at concentrations of 0.01–0.1 percent by mass, titanium gives steel high toughness, strength and ductility – that is, formability without breaking.

Because of their high strength, low weight and excellent corrosion resistance, titanium alloys are outstanding structural materials for shipbuilding as well as the aerospace industry. Despite their relatively high price, titanium alloys are the first choice for a wide range of applications, from outdoor sports equipment such as golf clubs to military protective vests.

Titanium vs. Zirconium

Titanium and zirconium both form a protective oxide layer and are among the most corrosion-resistant structural metals. The key difference: titanium is significantly lighter (4.50 g/cm³ versus 6.506 g/cm³) and is therefore the first choice in lightweight construction, shipbuilding and aerospace. Zirconium, on the other hand, scores with a very low neutron capture cross-section and is therefore preferred in reactor construction.

Get Titanium from E.WAGENER – Pure or as a Component

We don't simply offer you titanium. At E.WAGENER, you can decide for yourself how pure the material should be. We offer you 90, 95 or even >99% pure titanium as well as the common alloy grades 1 to 9. Direct further processing into blocks, wires, foils, sheets or rods is also possible. We can even produce custom components to your specifications. This is where you can particularly benefit from E.Wagener's years of experience with special materials. We know what matters.

Frequently Asked Questions about Titanium

What is titanium?

Titanium is a silvery-white light metal with high strength, low density (4.50 g/cm³) and excellent corrosion resistance.

Is titanium a heavy metal?

No. Unlike molybdenum, tungsten, tantalum, niobium and zirconium, titanium is a light metal.

What is titanium used for?

Titanium is used, among other things, in shipbuilding, aerospace, chemical plant construction, as a getter metal in vacuum technology, and as an alloying element in special steels. Pure titanium is also biocompatible and is used for medical implants.

Is pure titanium suitable for high-temperature applications?

Only to a limited extent: between 400 and 600 °C the physical properties of titanium change, and reactions with the surrounding environment, including ignition, can occur.

Which titanium alloys/grades does E.WAGENER offer?

E.WAGENER supplies pure titanium as well as alloy grades 1, 2, 3, 4, 5, 7 and 9 in 90%, 95% or over 99% purity.
