Zirkonium (Zr 702)
Zr is majorly used in reactor technology however it can be also be found in the construction of chemical equipments. The latter is due to its excellent stability against corrosion, its high strength and low density.
The material can be mechanically worked easily, but little filings and dust are easily inflammable. Under certain conditions it can be welded.

Due to its excellent corrosion resistance, niobium is also used in chemical construction. In many cases niobium can replace the more expensive and heavier tantalum. Niobium can also be used to produce superconductors and superconducting magnets.
Sodium vapour lamps contain niobium alloyed with 1% zirconium

Titanium possesses excellent corrosion and erosion properties. It has many diverse applications due to its high strenght and low density. Titanium is mechanically easy to deform and process, and can be welded. In chemical industries, it is an essential material in heat exchangers, containers, pipes and sterilization systems. Steam turbine blades and rotor discs are also made of titanium.
The aerospace field also relies heavily on titanium for its high strenght-to-weight ratio. The importance of titanium and its alloys has been growing steadily. It is biocompatible, and is therefore used in dental and bone prosthetics, pacemakers, and artificial heart valves in the human body, as well as in the veterinary field. Capillary tubes and extremely thin wires are used as material for canals.
We offer titanium from stock or special production. It is processed according to ASTM standards or German Technical Security Organization's datasheet 230. By request it can be certified with a company reference 3.1 B, 3.1 C, or 3.1 A on a separate account.

Density 10,2 Quality according to ASTM: B 365 (Rod) B 386 (Sheet, Strip)
Due to its high melting point of 2620°C Mo is an excellent material for high-temperature technology with vacuum and gas protection. Among other things this material is used in heat shields, heat conductors, pipes, evaporator and charge carriers.
It can mechanically be worked easily, but little filings and dust are easily inflammable. Under certain conditions Mo can be welded.
Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is wolfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten. A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth almost exclusively in chemical compounds. It was identified as a new element in 1781, and first isolated as a metal in 1783. Its important ores include wolframite and scheelite. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the elements. Its high density is 19.3 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material, making it difficult to work. However, pure single-crystalline tungsten is more ductile, and can be cut with a hard-steel hacksaw. Tungsten's many alloys have numerous applications, including incandescent light bulb filaments, X-ray tubes (as both the filament and target), electrodes in TIG welding, superalloys, and radiation shielding. Tungsten's hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are also often used as industrial catalysts. Tungsten is the only metal from the third transition series that is known to occur in biomolecules, where it is used in a few species of bacteria and archaea. It is the heaviest element known to be essential to any living organism. Tungsten interferes with molybdenum and copper metabolism and is somewhat toxic to animal life.

Due to its unusual corrosion behavior tantalum is often used in the construction of chemical systems. Heat exchangers, heating coils and plugs, coolers, sterilizers and chemical receptacle surfaces can be made of tantalum. It can also be used in the course of repairing enemeled containers.
Because of its good properties at high temperatures it is processed into heat conductors, heat radiation shields or parts in high vacuum ovens. Its biocompatibility makes it useful in medical technology.
Tantalum has excellent ductility and can be easily processed without producing shavings. It can only be machined with special lubricants. It can easily be welded but due to its sensitivity to oxygen and other gases this has to be done in a vacuum or with protective gas such as Argon.
Wire Ta-wire has been manufactured in diameters between 0,2 mm and 4,0 mm and could be supplied twisted with more cores. Available from stock are wires, annealed, in diameters of 0,5 mm and 1,0 mm
Rod Tantalum rod is produced in diameters from 3.0 mm to 63.3 mm. It is produced in lengths of 1000 mm to 2000 mm. We produce cylindrical material with diameters of 4.0 mm to 80.0 mm. Depending on size the surface is hammered or machined.
