Wire, round

dignity

Wire and the circle of rhenium represent a heat-resistant and at the same time very flexible, durable material, designed to work at t° above 1500 °C in aggressive industrial environments. Pure rhenium may be laminated in a thin wire with a thickness of 10 µm. Wire and the circle of rhenium have higher strength and corrosion resistance. This is one of the most refractory metals, which are used in metallurgical equipment, nuclear energy, industrial chemistry, Metalworking. Rhenium-platinum catalysts are indispensable for the production of high-octane gasoline. The most important field of its use rocket science, electrical engineering, catalytic chemistry, instrumentation.

disadvantages

This multiple element of the earth’s crust. Mining and production it is associated with a number of difficulties. This is a rather expensive and heavy metal, heavier than gold.

production

Rhenium semi-finished products produced by powder metallurgy methods. First, get the Fort. Then it is heated and rolled out a special rotary forging machine. So get the bars no thicker than 2−3 mm, which then, due to the high ductility of rhenium, pull in the superfine wire cross-sections up to 10 microns.

use

On the basis of rhenium and tungsten to produce tungsten-rhenium thermocouple BP-5, BP-20, which is designed for temperature measurement up to 2500 °C. Rhenium-platinum catalysts are indispensable for the production of high-octane gasoline. Alloys of rhenium durable, plastic, high-tech, well welded, can work in the most difficult conditions. Wire and the circle of rhenium are the main responsible of the fragments of nuclear installations. The rhenium wire is the basis of the filaments, meshes, cathode ray tubes, mass spectrometers, etc. similar devices. Alloys of tungsten with rhenium — much better suited for the manufacture of filaments than pure tungsten. In surveying instruments — levels, theodolites, optical mechanical assemblies use metal hangers from rhenium wire or thin ribbon. Niobium and tantalum produce energy-intensive electrolytic capacitors.

quality requirements

On the valid samples of insignificant defects, the risks, the traces of broach, shrinkage irregularities, which fall within the boundaries specified by the standard deviations. To cut the circle and the wire must not contain foreign inclusions. The surface must be clean, free of cracks, burrs. Rolled in original packaging stored in closed warehouses. It can be transported by any transport. When shipping wire and should be protected from mechanical damage, moisture, dirt, corrosive substances.
