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 copper nano powder will also be affected.
What is copper powder?
Copper is the earliest discovered chemical element. Its chemical symbol is Cu, atomic number is 29, and atomic weight is 63.546 U.
Pure copper is a soft metal, the surface for red-orange, when just cut with a metallic luster, good ductility, high thermal conductivity, and electrical conductivity, therefore in the cables and electrical and electronic components is the most commonly used material, also can be used as a building material, as well as the composition of many kinds of alloy, such as for jewelry sycee, used to produce Marine hardware and cupronickel coin and used for strain gauge and constantan thermocouple. Copper alloys have excellent mechanical properties and low electrical resistivity, the most important of which are bronze and brass. Copper is also a durable metal that can be recycled many times without damaging its mechanical properties.
Copper does not react with water but slowly reacts with oxygen in the air to form a tan layer of copper oxide, unlike the rust that forms when the iron is exposed to damp air, which protects the underlying copper from further corrosion. Copper is easily corroded by halogens, tahalides, sulfur, and selenium, and vulcanized rubber can blacken copper.
What is a copper powder used for?
The most common use of copper is for electric wires, which are usually made of pure copper today because it is second only to silver for conducting electricity and heat, but it is much cheaper. Copper is also easy to work with, changing shape by melting, casting, and calendering to make parts for cars and electronics. These processed copper products are collectively referred to as "stretch copper products".
And copper can be used to make a variety of alloys, copper important alloys are the following:
Brass is an alloy of copper and zinc, named for its yellow color. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, gun casings, faucets, and so on. Brass sounds good when struck, so gongs, cymbals, bells, trumpets, and other Musical Instruments are made of brass.
An alloy of copper with zinc and tin, resistant to seawater, used for ship parts and balancers.
The alloy of copper and tin is called bronze, named for its green color. It was a common alloy in ancient times (e.g., in China's Bronze Age). Bronze generally has good corrosion resistance, wear resistance, casting ability, excellent mechanical properties, and high hardness. Used for manufacturing precision bearings, high-pressure bearings, seawater corrosion-resistant mechanical parts on ships and various plates, pipes, bars, and so on. Bronze also has the unusual property of "thermal shrinkage and cold expansion", which is used to cast statues that expand when cooled to make the features clearer.
Phosphor bronze is an alloy of copper, tin, and phosphorus, containing 2%-8% tin, and 2-8% phosphorus, the rest of the composition is copper. Hard, can make springs. Casting can be used for gear, worm gear, bearing, and other mechanical parts.
White copper is a copper and nickel alloy, its color and silver, silver shine, not easy to rust. It is often used to make coins, electrical appliances, meters, and ornaments.
18 Karat gold (18K gold or rose gold)
An alloy of 6/24 copper and 18/24 gold. Red and yellow, hard, can be used to make jewelry, and ornaments.
What is copper nanopowder used for?
As an alternative to more expensive metals, copper nanopowders are ideal for reducing production costs and are widely used in microelectronics processes, conductive pastes, and nanometal lubricant additives. It can be used for:
Antifungal, antifungal, and antifungal agents
High strength metals and alloys
High thermal conductivity material
Conductive inks and pastes for printing electronics
Sintering additives and capacitor materials
Lubricating oil additive

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash. After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.
After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.
Dorsey called Twitter his biggest regret, saying, “The idea and service is all that matters to me, and I will do whatever it takes to protect both. Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.
"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.
He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path... I believe it with all my heart."
Besides, because of the ever-changing international situation, the supply and prices of international bulk copper nano powder are still very uncertain.
