Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk WNiFe alloy powder are still very uncertain.
What is Tungsten Nickel Iron W-Ni-Fe Alloy?
Tungsten-nickel-iron alloy is an alloy composed of tungsten matrix with a small amount of nickel and iron.
Tungsten nickel iron alloy has the characteristics of high density (~18.8g/cm3), strong absorption of high-energy rays (higher than the ray absorption coefficient of lead), low thermal expansion coefficient (4-6 ×10-6/℃), good plasticity, high strength and elastic modulus, machinable and weldable, etc.
It is widely used in radiation protection and guidance, industrial counterweight parts, security and defense parts, etc.
What are Tungsten Nickel Iron Alloy properties?
Specific significance: ~18.8g/cm3 high density
High strength: tensile strength of 700-1000mpa;
Strong ray shielding ability: under the condition of the same thickness, the ray shielding ability of tungsten alloy is more than 1.7 times that of lead. When the ray is stronger, the difference in ray shielding ability between the two is more obvious.
High thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;
Small thermal expansion coefficient: the thermal expansion coefficient of tungsten is 4-6 ×10-6/℃, only 1/2-1/3 of iron or steel;
Good shaping, machinability and weldability;
Compared with lead, which is toxic, tungsten alloy material has environmental protection characteristics, and it does not harm human safety when making radiation detector with tungsten alloy shielding parts.
Compared with W-NI-Cu alloy, W-NI-Fe alloy has certain ferromagnetism, its mechanical properties and machining properties are better than W-NI-Cu alloy.
What is Tungsten Nickel Iron Alloy Used For?
Radiation protection and guidance: Because of its high density (~18.8g/cm3), excellent X-ray and gamma-ray absorption capacity, excellent processing, tungsten nickel iron alloy is the ideal material for radiation therapy collimator and protective parts. It can be used in all kinds of CT, linear accelerator, PET, γ camera and other equipment, radiotherapy, nuclear medicine, and other fields.
Industrial counterweight components: Tungsten-nickel-iron alloy counterweight components are key components in many different applications, compensating for swings, weight transfers, imbalances and vibrations to form or change the center of gravity, ensuring excellent balance. Applications include aerospace, automotive, sports equipment, oil and gas drilling, gas turbine counterweights, and precision optical instruments.
Security and defense components: In modern warfare, the main targets are tank armor, fortified fortifications, and protected fighters. If you want to obtain the fatal impact effect, high density, high storage speed, strong penetration ability, high-performance materials are indispensable. Tungsten-based materials with high specific gravity can fully meet these needs, and are indispensable materials in the field of national defense and security.
Nuclear power and energy components: due to its high density and performance, after precision machining, the device is used as an inertia flywheel in the main pump of the nuclear power cooling system, so as to ensure that the main pump system can continue to work and cool the nuclear power plant to avoid accidents in the event of a sudden power failure.
Aerospace parts: Tungsten-nickel-iron alloy with high temperature strength and erosion resistance, widely used in aerospace parts.
