Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet and rod of tungsten alloy VNZh 95. The supplier guarantees timely delivery of products to any address specified by the consumer.

Technical specifications

Alloy VNZh 95 refer to heavy alloys of tungsten with nickel and iron. The material is produced using powder metallurgy technologies followed by sintering.

A characteristic property of the alloy is its high density, high value of the elastic modulus and the absorption coefficient of ionizing radiation, for example, gamma radiation or high-energy X-ray radiation. The workability of the VNZh-95 alloy is better than that of pure tungsten. The alloy is also distinguished by high values of rigidity, resistance to vibrations, good heat and electrical conductivity, low thermal expansion.

Urgency of application

Alloy VNZh 95 is used:

In the aerospace and watch industry (rotor blades of turbine engines, screws, inertial systems, balancing rods, counterbalances of watch mechanisms, trim tabs, etc.);

In nuclear technology (components of storage tanks for radioactive fuel or its components);

As elements of non-destructive test equipment (diagnostics and dosimetric control);

In medicine (collimators for X-ray and radiation therapy facilities, production of radiation protection equipment);

In security equipment (baggage x-ray machines on transport terminals of airports and airports);

In the petrochemical and gas industry (components of devices for radioactive well logging);

For the production of metalworking and welding tools (rods, extensions, die casting molds, extrusion stamps, highly resistant electrodes).

Chemical composition

The composition of the alloy VNZh 95 includes:

Tungsten — 95%;

Nickel — 3,2… 3,7%;

Iron — 1,5… 2,0%.

Physical and mechanical properties

Density, kg / m3 — 17900… 18100;

Modulus of elasticity, GPa — 375;

Sorting and processing features

Alloys of grade ВНЖ 95 are supplied in the form of cold-rolled sheet and rod, and also in the form of bars and plates with mass from 100 kg to 1000 kg. It is characterized by weak magnetic properties, which should be taken into account in the technology of machining.

Supplier — AvekGlob company — offers to buy at affordable prices from the producers of sheet and rod, which are made of alloy VNZh 95. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
