How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for WNiFe alloy powder will also be affected.
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 day after the shooting at a Texas elementary school, the National Rifle Association issued a statement saying it "extends its deepest sympathies to the families and victims involved in this terrible and evil crime," adding it would "reflect on these events and pray for the victims."
It comes just days before the National Rifle Association's annual convention in Houston, Texas. Houston is less than five hours away. Texas Governor Tony Abbott, Senator Ted Cruz, and others are scheduled to attend the event, which has also caused a lot of controversies.
Texas Democratic gubernatorial candidate Mark O 'Rourke took to social media to call on Abbott to pull out of the convention, urging that it be held outside Texas. Many American netizens also took to social media to express their dissatisfaction. "I wish the NRA's annual meeting was held three days after 19 children and two adults were massacred," said one. "The school shooting was not a lone Wolf, but with the help of the NRA."
Between 2000 and 2020, US gun manufacturers produced more than 139 million guns for the civilian market, according to the Justice Department report. The NATIONAL Rifle Association (NRA) is one of the leading gun rights advocates with more than 5m members and deep pockets. The United States has not passed major gun control laws for more than two decades, blocked by gun interests.
The WNiFe alloy powder price is predicted to increase in the next few days.
