On the podium, Antonio Ducati's speech has begun.

The title of his speech was "The Application and Current Situation of Motorcycle Aluminum Materials in the World".

"I think all the professionals here must know the characteristics of aluminum alloy. It has many characteristics such as light weight, good texture, and wide application."

"At present, aluminum alloy materials are widely used in large-displacement motorcycles with a capacity of more than 125ml. However, compared with the use rate of other alloy materials on motorcycles, the application of aluminum alloy materials is still much inferior."

"Today, I want to discuss with you the topic, what kind of prospects does aluminum alloy have in the motorcycle industry..."

At the beginning of the speech, Antonio Ducati quickly brought everyone into the topic with his unique entry point.

In the podium, Zhao Guoyang nodded silently as he listened to Mr. Antonio's talk.

In fact, in the era before Zhao Guoyang's rebirth, the promotion and application of aluminum alloys gradually became popular in the global motorcycle manufacturing industry.

Moreover, it is widely used in relatively high-end cruise cars, special vehicles and other models.

Judging from Zhao Guoyang's knowledge reserves beyond this era for 20 or 30 years, this Mr. Antonio was able to vigorously advocate the use of aluminum alloys in the motorcycle industry in the early 1990s, which was considered to have a very advanced vision.

Li Kejian, who was standing by, glanced at Zhao Guoyang's approval and asked, "Why, Guoyang, have you also studied materials science? Do you know the characteristics of this aluminum alloy material again?"

After hearing this, Zhao Guoyang's face was stunned.

Seeing Mr. Li’s expectant gaze, he coughed gently, touched his chin and said, “Mr. Li, I learned some things when I was on a business trip to Shagang Group before. At most, I can only be considered a little bit…”

When Li Kejian heard this, he seemed to remember something and said "hum" and said, "Shagang Group, I know this."

"Their Chairman Shen Zhirong is a personal figure. As long as he is in charge of planning, our domestic steelmaking industry will definitely have a place for Shagang Group in the future!"

Zhao Guoyang agreed with Mr. Li’s judgment very much, and nodded in agreement immediately.

"By the way, the Shagang Group should be able to do the new aluminum alloy pressure castings that Antonio just mentioned, right?" Li Kejian tilted his head and asked Zhao Guoyang casually.

"Well, it should be OK. This material is currently widely used on bicycles. It uses the s35c welded body and the a2107 integral forged pedal. All of them can be switched to aluminum alloy die-casting parts."

"In this way, the cost of construction should be reduced by a large amount!" Zhao Guoyang said casually.

What he didn't notice was that after he said this, Old Li next to him showed an "old fox" smile.

While the two were communicating in a low voice, Antonio Ducati on the stage had already talked about important points.

"As we all know, the application of aluminum alloy on the frame accounts for the lowest proportion of all parts. So today I want to focus on discussing with you is the topic in this regard..."

After Antonio said this, Li Qinan and Sun Zhengxiao in the back row looked at me and I looked at you, looking at you, looking at you, looking at you with a confused look on his face.

After a while, Li Qinan first reacted and said, "Mr. Sun, is this Mr. Antonio talking nonsense? Isn't this a mess with the use of aluminum alloy in terms of frames? Is it necessary to discuss?"

Li Qinan's words are not just a silence. The motorcycle frame has very high requirements for rigidity.

The reason is simple, the frame is another important component on a motorcycle in addition to the core engine.

If the rigidity is too low, the frame will be bending and deformed due to the moment generated by the rear wheel force.

The natural sense of manipulation affecting riders is secondly. If it is severely deformed, the car will be destroyed and the person will die.

Therefore, in the domestic motorcycle manufacturing industry, frames should usually be made of high-strength materials.

As a light material, aluminum alloy has indeed not been used by manufacturers in terms of frames.

Listening to Li Qinan's complaints, Sun Zhengxiao, who was standing beside him, also expressed his agreement with a solemn expression.

Although their Jialing Group is currently considered by many industry insiders to be the leader in the domestic motorcycle industry, according to the market feedback to various companies, the Chongqi Group's frame has received higher evaluations.

Therefore, in terms of body structure and frame, Sun Zhengxiao dare not regard himself as the "boss".

While the two were discussing quietly here, on the other side, Mr. Kawasaki from Kawasaki Co., Ltd. was also whispering to his beautiful assistant, Kiko Aso.

Mr. Kawasaki narrowed his eyes and sighed: "Kiko, this Mr. Antonio, really dares to think about it!"

"Although the application of aluminum alloy castings on motorcycle frames has been in place for a long time, there have been few successful examples, right?"

Aso nodded slightly and said, "Hai, President Kawasaki! As far as I know, the application of all-aluminum frames should be the first to be on the road racing car (ducati500) in 1979."

"However, in order to avoid controversy, the body of this car was painted black to cover up the original appearance of the all-aluminum frame."

Kawasaki Ou said "huh", nodded and smiled, "Yes, if they hadn't done this at the time, those racers would probably not dare to drive this car, haha!"

Aso Kiko smiled reservedly and continued to speak: "Yes, President. This matter was not officially released until 1987."

"The purpose is of course to prove that it is one step ahead in aluminum alloy frames..."

"Yaxi, this is right!"

Kawasaki nodded repeatedly: "Since Harley's HD550 and Honda's RZV500 were launched in 1985, various manufacturers have intervened in the field of aluminum frames. Ducati is naturally unwilling to be lonely and can't help but announce its previous 'glorious deeds'."

Aso Kiko responded and smiled slightly, "Yes, Ducati's application in this area is indeed ahead of the same industry. Even companies such as BMW and Harley have to admit this!"

"Haha, even if you admit it, they won't say it!" Kawasaki O's smiled and waved his hand to Aso Kiko.

"Okay, let's continue listening. Look at this Mr. Antonio, what else is amazing!"

On the podium, Antonio was in high spirits and hyped the prospects for the application of aluminum alloy frames.

He raised his arms and gestured loudly, saying, "As we all know, the requirements for motorcycles for frames are nothing more than three aspects: one is to have good rigidity; the other is to reduce weight as much as possible while achieving controllability; and the third is to resist strong vibrations of high-performance engines."

Speaking of this, Antonio Ducati paused for a moment and said jokingly: "Of course, beauty is definitely one of the requirements of the frame. Even if I don't say this, everyone should understand it."

Listening to the teasing words of the thin Apennine man, the audience laughed knowingly.

Li Kejian, who had been listening carefully, couldn't help but ask Zhao Guoyang after listening to Mr. Antonio's words: "Guoyang, how do you understand this aluminum alloy frame? Do you think it is possible to be realized in our domestic frame production?"

Zhao Guoyang was stunned for a moment, then shook his head and said, "Old Li, I think our domestic frame factory does not have such production capacity for the time being."

It seemed that the strength was not enough, Zhao Guoyang explained: "Speaking of this, our Hongda Machinery Factory started with iron devices such as frames and fuel tanks. I still know a lot about frames..."

Li Kejian said "yes", nodded, and signaled Zhao Guoyang to continue speaking.

"Old Li, you should know that welding aluminum alloys is much more difficult than iron devices. The requirements for welding quality are also much higher."

"In order to improve the welding quality, it is necessary to strictly control the welding fusion between parts with large melting points, set the best gap, and select workers with extremely excellent welding technology to operate..."

Speaking of this, Zhao Guoyang couldn't help but sigh and said, "At least in the current view, our Hongda Machinery Factory does not have such a requirement."

Maybe he felt that he was saying too absolute, Zhao Guoyang added: "Old Li, I am not trying to increase the ambition of others and destroy my own dignity."

"In fact, the welder level in our factory is still OK. It is mainly about the welding performance of aluminum alloy parts. Everyone is not familiar with it. The difficulty of operating is invisibly much greater..."

After Zhao Guoyang's explanation, Li Kejian nodded silently and expressed his understanding.

In fact, Zhao Guoyang has another thing that has not been said is that even if the welding process is barely achieved, few domestic frame manufacturers can complete the subsequent treatment of alumina film.

In Zhao Guoyang's memory, after the aluminum alloy frame is welded, the treatment of the alumina film is also a key point.

If the alumina film cannot remain bright, smooth and even, it will seriously affect the strength of the frame.

Zhao Guoyang's explanation made Li Kejian understand it at all.

He said with a little sadness: "Guoyang, you are right, just like in the automobile industry. Although the application of all-aluminum frames has begun to become popular internationally, none of our domestic independent automobile manufacturers can master this technology..."

"Speaking of this, this is not a problem with your Hongda Machinery Factory at all, nor can it be solved by relying solely on Guoyang, you alone..."
