Chapter 482 Cooperating with the National Team

"These purchased finished materials are not good. The test results show that the strength and toughness cannot meet our requirements."

Wang Dali picked up several small black cylindrical tubes on the table, played with them for a while, and said with a frown.

The engineer next to him said with a wry smile.

"Boss, the only common giant magnetostrictive material on the market is Terfenol-D. This material has been on the market for decades, and the manufacturing process is very mature. It can also be produced in China."

"Manufacturers can supply various finished products such as rings, tubes, round rods, and powders, and the prices are not expensive. They can also provide processing such as slotting and lamination to reduce losses."

"This is actually enough for ultrasonic transducers."

"You know, Johnson & Johnson's ultrasonic scalpels use piezoelectric ceramics. We can use magnetostrictive material rods, which are already more advanced than Johnson & Johnson's products."

Wang Dali shook his head: "But its own strength is not high, it is very brittle, and it cannot be processed deeply. At the same time, it cannot maintain high-intensity work under high power."

"Otherwise, let's look at other functional materials."

The engineer said with a grimace: "We have tried Galfenol (iron-gallium alloy), iron-cobalt-vanadium alloy and some iron-nickel alloys, but we can't find any better materials."

So he pondered for a moment and then ordered: "Let's do this. You agree first. After he comes and sees the technical information, we can discuss it together and study whether it is feasible."

Wang Guiqing continued: "Mr. Wei, I heard that Sanqing has developed an ultrasonic scalpel. The transducer inside uses a super magnetostrictive material? Did you develop this material yourself?"

"I'm sorry, your new material is too powerful. It may be classified. I have to report it to my boss."

He also had a straight face, nodded and said: "Since your company takes this new material so seriously, then I will listen to you."

"It's true! Such a powerful giant magnetostrictive material actually exists!"

"In fact, the first giant magnetostrictive material, Terfenol-D, was born at the Eagle Nation Naval Weapons Laboratory. It was used decisively in the early days and became a strategic material prohibited from export."

As the R&D base for new materials in China's metallurgical industry, it develops and produces a large number of key materials for key projects such as launch vehicles and manned spacecraft. It is a top international R&D center in the field of materials.

There was a "pop" sound.

Feng Qihang then nodded: "I see, why don't they use existing products on the market? Can't Terfenol-D?"

"Hello, Mr. Wang, why are you free to call me today?"

"Let me ask, have you applied for a patent for this giant magnetostrictive material?"

"Could it be that the technology was bought from somewhere, was deceived, and then wanted to make it with us in a whimsical way."

Wang Guiqing smiled and said: "No, the superiors sent me to ask."

"It is said that it does not meet the requirements of their products, so they want to cooperate with us to produce a new material."

Wang Dali chuckled and said: "We don't need them to develop it, we have our own ready-made material formula."

Feng Qihang couldn't help but want to laugh when he saw the serious look on his face.

He couldn't wait to ask: "Do you have any performance parameters? Show them to me."

"It seems we can only ask the national team for help."

His heart suddenly sank, and he felt that this situation was not impossible.

"Sorry, because this involves our company's top-secret technology, please sign a confidentiality agreement."

Both parties sat down separately in the conference room.

China Iron and Steel Research Institute, a subsidiary of the Functional Materials Research Institute.

"People from the navy?" Wei Kang was a little surprised.

Wei Kang's heart moved and he said casually: "Yes, as expected of Mr. Wang, he is well informed."

"But for this material, my initial purpose was just to make a transducer for Sanqing's ultrasonic scalpel. I had no other ideas."

The complicated formula and manufacturing process inside made him dizzy just by looking at it.

Several other technicians at the institute also stared blankly at the ppt, unable to say a word.

"Whether it is the invention or early application of this material, it is directly related to the military industry, especially the navy."

Wang Dali shook his head even more: "No, Johnson & Johnson and Medtronic use piezoelectric ceramics as transducers."

Especially after seeing the alloy ratio and analysis, he was completely shocked.

"This is a breakthrough achievement. Since Terfenol-D was developed at the Naval Laboratory in Eagle Country, the world has been developing giant magnetostrictive materials. However, in recent years, research and development has been somewhat stagnant."

Magnetostriction coefficient: ≥10000PPM

Tensile strength: ≥250Mpa

Compressive strength: ≥2600Mpa

Curie temperature: 1080℃

Wei Kang grinned: "As it should be, the development of Sanqing is inseparable from the support of the country. It is natural to be able to contribute to aerospace and national defense."

"We now have a very urgent need for related materials, especially in the development of sonar systems and ultrasonic weapons."

The engineer was immediately overjoyed: "That's great, let's order it directly from them."

"Bah bang bang!"

"Dean Feng," he looked at Feng Qihang expectantly: "What do you think of this material? Is it difficult to produce it in the laboratory?"

"These guys are all masters of ultrasonic surgery, especially Johnson & Johnson. The first ultrasonic surgery was made by them. It was the ancestor of ultrasonic surgery. It has been decades, but piezoelectric ceramics can still be used.

What's the trick?"

"Until now, Sanqing Group has quietly made such a major breakthrough. It's so surprising. It is definitely the biggest achievement of our materials industry in recent years!"

Feng Qihang was immediately surprised: "Is it that pharmaceutical group Sanqing? Aren't they a pharmaceutical company? How can they research rare earth alloys?"

When I heard this, I immediately understood that this transducer material must have attracted the other party's strong attention.

"What?" Feng Qihang stood up from his chair in shock: "Can Sanqing develop new materials? Or super magnetostrictive materials?"

Wei Kang secretly breathed a sigh of relief and said with a smile: "It does happen. You also know that when it comes to rare earth alloy research and manufacturing, the Iron and Steel Research Institute is the national team and the strongest. We can't produce it ourselves, so we can only look to them.

Cooperation."

"You also know that foreign companies are relatively strong in the field of medical equipment. We have to snatch meat from the mouths of a group of wolves, so naturally we have to work hard to develop new technologies."

"Mr. Wei, are you using too much force to grab the meat?"

The person who responded was a researcher, holding a piece of paper in his hand, with an expression of shock and a hint of joy on his face.

"Believe it or not, the patent pool alone has been filled with holes, and you can't get around it at all."

"If you follow others, you can only step on their footprints. How can you fight with them?"

Before Wei Kang could react, Wang Guiqing hurriedly explained: "Mr. Wei, when the people from the Navy heard about this, they rushed over immediately and are right next to me. How about we talk together?"

"Come, everyone applaud with me and express warm congratulations and sincere gratitude to the comrades of Sanqing!"

However, Feng Qihang's next words made his smile freeze instantly on his face.

Although he has obtained a lot of high technology from the system, he does not fully understand many of the technical details. Basically, he leaves it to his subordinates to develop and learn.

Wang Guiqing laughed and said: "Oh, listen to Mr. Wei's tone. It's nothing surprising. It's such an understatement. He deserves to be the King of Chinese Medicine."

The researcher shook his head: "No, it's the Sanqing Group."

The researcher interjected: "They are not looking to us for research and development, but for production. They have already developed a new rare earth alloy. Because they have strict requirements on the production process, they asked us to cooperate."

It was Wang Guiqing on the other end of the phone, smiling and saying: "Mr. Wei, you are a very busy man. How can I usually disturb you?"

Wang Dali looked at the scene in front of him and was completely shocked.

Feng Qihang couldn't help but frown: "Terfenol-D is already a very mature product with a wide range of uses. If it doesn't meet the requirements, their standards for new materials must be very high."

"So, we can only change our research and development ideas and use magnetostrictive ultrasonic scalpel."

Wang Dali asked back: "Do you think that with the level of these manufacturers, they can create a brand new rare earth alloy based on the formula?"

"It's not that I'm well-informed, but I was told by the China Iron and Steel Research Institute. They said that Sanqing Group came to cooperate in the production of a new material. It has made a huge breakthrough in the field of super magnetostrictive materials and can be used in

Aerospace, as well as the Navy’s sonar system, so I report to the higher ups.”

"Buzz buzz~" The mobile phone on the table rang.

"Yes." The researcher handed over the paper in his hand, on which he simply wrote some parameters of the new material.

"Feng Yuan, we have received a request for technical cooperation from an enterprise. They want to produce a super magnetostrictive material for use as an ultrasonic transducer. Can we provide a batch of samples first?"

Feng Qihang grabbed it and immediately scanned it.

The engineer rubbed his forehead and said worriedly: "There are only these ready-made civilian materials, and the choices are very limited. Is it possible to let the manufacturers improve and develop the materials themselves? That would be too difficult. I don't think they have the strength."

He secretly thought to himself that among these new projects, the artificial heart was more of a gimmick and could attract people's attention, but it would not make the superiors call him specially.

After finally finishing speaking, he showed an awkward but polite smile, rubbed his hands and said, "That's pretty much it."
