Chapter 779 Third Generation Aeronautical Materials

Chen Huaiqing and Han Yang then had a long exchange, and Ren Fei was naturally by the side.

Han Yang didn't intend to change his previous plans, such as the Rongyu Economic Zone.

The two cities of Rongyu and Chongqing are originally located in the hinterland. If they don't develop together, it really won't work.

The other is about the University City.

Han Yang didn't think there was any problem with invigorating the city with science and education.

The university town in Rongcheng has developed quite well, and many new industries have formed around the university town in Rongcheng.

Take computer games, for example.

Han Yang doesn't play games, but that doesn't mean he doesn't pay attention to them.

In China, there are still many people who don't know what computers and the Internet are, but in the cities, the wave of the Internet has begun to sweep.

Chen Huaiqing also publicly said that the Internet will change the world's discourse, and let countless people invest in it.

Other changes are not deeply felt, but the more convenient communication and faster information acquisition can be regarded as really felt.

It was something that happened not long ago, and it was spread throughout the whole country.

The speed of development of Internet news is quite fast.

Chen Huaiqing didn't get too involved in the matter of Yuzhou being re-directed directly under the central government. After attending the opening ceremony of the United University, he went directly to Southwest Aluminum.

Metal aluminum In the history of mankind, the time for large-scale use of aluminum is not long.

Before the 19th century, aluminum was a rare metal. At that time, European royal families were proud of using aluminum tableware, which was a symbol of wealth and power.

Up to now, the production and smelting of aluminum has become very common.

In the aviation industry, aluminum alloys have begun to be used in large quantities. Compared with steel, aluminum alloys are lighter in weight.

The weight of the aircraft is reduced, so it can carry more cargo or reduce fuel consumption.

Southwest Aluminum is a factory built during the third-line project period, and the factory code name is 112 Factory of the Ministry of Metallurgy.

Of course, the factory code is no longer used anymore.

Southwest Aluminum has a very important position in China's industrial industry. Before the 6-ton die forging press was developed, the 3-ton die forging hydraulic press here was the strongest in the country.

Used to make forgings for the H-6.

The enterprise reform in Yuzhou has spread from local enterprises to the entire enterprises in Yuzhou. The Southwest Aluminum Processing Plant has also carried out shareholding reform.

Southwest Aluminum was established!

Mota Holdings is the largest shareholder of Southwest Aluminum, accounting for 20.00% of the shares.

20.00% becomes the largest shareholder?

Southwest Aluminum also has several major shareholders, including Shuchuan State-owned Assets and Yuzhou State-owned Assets, and the other two major shareholders are Huaguo Aluminum and pension fund companies.

Southwest Aluminum is a listed company on the Southwest Stock Exchange.

Now the main products are: aviation aluminum alloy, aluminum alloy thin plate, special-shaped aluminum alloy ring, etc.

By the way, aluminum alloy windows are also a product category developed by Southwest Aluminum.

Southwest Aluminum is also actively developing and researching in the field of building materials.

Nowadays, high-rise buildings are constantly being built everywhere, and the demand for aluminum alloy building materials is quite large.

The aluminum alloy building materials produced by Southwest Aluminum are very popular in the market because of their large brands and good quality.

After all, Southwest Aluminum, upon hearing the name, knows that it is a big company.

In addition to ordinary civilian products, Southwest Aluminum has invested a lot of effort in research and development of aviation aluminum alloys.

Southwest Aluminum is the main supplier of aviation aluminum alloys for Murta Aircraft.

At this time, about 80.00% of the materials in aircraft manufacturing are made of aluminum alloy.

Unlike in the future, a large number of composite materials are used, and the use of aluminum alloy materials on aircraft has dropped to 20.00%.

In addition, Southwest Aluminum is still developing aluminum alloys for automobiles.

Today's cars are basically made of steel.

Compared with the price of aluminum alloy, the price of steel is cheaper.

In this case, if steel is used, the production cost of the car will naturally be lower.

However, in the next few years, environmental protection will become a general trend.

Under the pressure of environmental protection, automakers naturally have to try various methods to reduce fuel consumption.

After all, automobile exhaust emissions are the main source of pollution.

If you want to reduce fuel consumption, there is a very simple way, that is to reduce the weight of the car.

Everyone knows that there is a big difference in fuel consumption between four people and one person in a car.

If you want to reduce the weight of the car, then the use of aluminum alloy parts is undoubtedly a very good choice.

That's how the aluminum alloy engine came about.

Compared with cast iron engines, aluminum alloy engines are 30.00% lighter in weight.

Although it is about 20 pounds.

Don't look too small at 20 catties, it's already a lot.

However, the price of aluminum alloy engines is much higher than that of cast iron engines.

One is because of the technical difficulty of aluminum alloy engines, and the other is the price of aluminum itself.

Electrolytic aluminum is a heavy polluting industry.

In addition to finding a way on the engine, it is on the body and some parts of the car.

However, the processing of aluminum alloy is also very demanding.

Anyway, if aluminum alloy wants to be popularized in automobiles, it is quite difficult, there are technical factors, and there is price.

Chen Huaiqing came to Southwest Aluminum mainly to look at aviation aluminum alloys.

Southwest Aluminum has developed a new aluminum alloy material called aluminum-lithium alloy.

This belongs to the third generation aviation aluminum alloy.

In 1983, Alcon Aluminum Company and Alcor Aluminum, the two largest aluminum alloy manufacturers in the world, announced at the same time that they had successfully developed a new revolutionary material, aluminum-lithium alloy.

In fact, this material has been discovered a long time ago.

Of course, being discovered and applied are completely different things.

It's like graphene!

It took many years from discovery to application.

In theory, graphene can be used to make chips, batteries, etc., but there has been no breakthrough in technology.

Alcon Aluminum and Alcor Aluminum launched practical aluminum-lithium alloy materials, which is undoubtedly a breakthrough.

This material has good performance in terms of specific gravity, stiffness, strength, corrosion resistance, fatigue resistance and ductility.

Compared with the second-generation aviation aluminum alloy, it is definitely much better.

Aluminum-lithium alloys are not only used in the aviation field, but also in the aerospace field.

In the past, Huaguo hadn't mastered this technology at all. Now that Southwest Aluminum has developed it, it will be extremely beneficial to Murta Aircraft.

Of course, although the research and development is successful, it will take some time for large-scale industrial production.

Chen Huaiqing came here with some praise for the aluminum-lithium alloy research and development team.

With this kind of material, it is undoubtedly extremely important for Huaguo's aviation industry.

At least on the material, there will be no things like getting stuck.
