What is Tungsten Nickel Iron W-Ni-Fe Alloy?
For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for WNiFe alloy powder will grow as fast as the wealth of the rich during the pandemic.
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.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled WNiFe alloy powder are estimated to be influenced by international political situation changes.
