Automotive Black Technology Chapter 678: : Aluminum alloy as hard as diamond!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
Aluminum, this thing is too familiar to Li Fanyu.
According to statistics, the aluminum content in the earth's crust is about 8%. It is the most abundant element besides oxygen and silicon. It is also the most abundant metal element in the earth's crust. It contains a large amount of aluminum silicate way, widely distributed and stored beneath the earth's surface.
Humans have used aluminum as early as the Stone Age; many pottery unearthed in prehistoric times were made of clay containing a large amount of aluminum compounds.
However, because the oxidizing property of aluminum compounds is very weak and aluminum is not easily reduced from the compounds, it has not been developed for a long time.
It was not until 1985 that the German chemist Deville used the nanosubstitution method to reduce impure aluminum ingots, and this matter was not taken seriously. However, due to the difficulty of refining it at that time, aluminum was worth about the same as gold and silver, and was called "silver from clay."
It is said that Napoleon had a favorite set of tableware, which was made of aluminum. I don’t know if there was any talk of aluminum poisoning at that time. If you eat with aluminum tableware every day, how many fried dough sticks will you eat?
However, the value of aluminum only lasted for thirty years. At the end of the 19th century, after the American CM. Hill used electrolysis to extract high-purity aluminum from ice crystal ore, this kind of aluminum was originally enjoyed by the emperor. , finally took off the noble halo and walked into the homes of ordinary people.
To date, aluminum alloys made by mixing aluminum with other elements have become important materials in industrial and civil fields. It is widely used in aviation, construction, electronic products and automobiles.
It can be said that among all the current car companies in China, Zhengxin's skill in playing with aluminum is simply superb.
Zhengxin’s ZGX series engine bodies and the bodies of A8, RS, and Longbow all use a large amount of high-strength 7050 aluminum alloy.
So when he saw that what was unlocked in the materials laboratory was super aluminum, Li Fanyu was immediately interested. He directly clicked on the option and brought up the introduction of this material.
"The super metal series is the basic material used in X technology. It can be combined with other super technologies to create parts or machinery with performance and reliability far superior to the current time and space.
Super aluminum metal includes five main balance alloys of aluminum elements with different strengths. After unlocking the material, current test users can directly produce it from the super material laboratory by redeeming points, or they can also spend additional points to redeem a full set of production processes.
Tip: If the X element is not added to the super metal, the standards of the super metal produced with the current time and space technology will be reduced by 10%. Various standards include; tensile strength, yield strength, elastic modulus, hardness, and density. ”
Ah? !
After Li Fanyu saw this introduction, his eyes widened.
In other words, can this so-called basic material of X technology be produced by oneself?
Damn it! Xapp, you have grown up!
When super memory alloy first appeared, Li Fanyu thought of using this kind of thing to make a fortune. But one reason is that because of his limited time, he cannot focus on production in the materials laboratory.
The second reason is also because this thing is too evil. If you rashly spread this unexplainable thing, your own black technology will be suspected of being exposed. Therefore, even though the market demand was so large at the beginning, he did not continue to expand the memory alloy business.
But if you can exchange for craftsmanship and produce it yourself. So...engine, body, wheel hub...aircraft fuselage, landing gear, aero-engine blades...the market is huge!
Faced with such an awesome thing, what else could Li Fanyu say?
I can only hold on to my surging heart and shout, "Hold the Grass!"
Thinking of this, he quickly opened the options and entered the X Super Aluminum panel.
As expected, as the introduction said, after opening the panel, five sub-categories of aluminum alloys were presented in front of Li Fanyu.
Opening them one by one, Li Fanyu’s heart was beating wildly!
Disregarding the tensile strength, yield strength, elastic modulus, density and other data, just seeing the hardness of No. 1 to No. 5 X super aluminum alloy made him feel like he was going to make a fortune.
The mechanical properties of the five aluminum alloy subcategories increase as the number increases. No. 1 X aluminum alloy has the lowest hardness, with a Mohs hardness coefficient of 8.
But even after seeing the worst hardness, Li Fanyu, who had seen a lot of strong winds, couldn't help but be shocked!
Mohs hardness is 8! What concept?
Let's put it this way, the Mohs hardness of iron is only 4-5 depending on the smelting process. The hardness of high-quality stainless steel is only 6. Diamond, the hardest material currently existing in nature, has a Mohs hardness of only 10!
Seeing the most basic No. 1 X aluminum alloy, Li Fanyu covered his racing heart and directly opened the last subcategory - No. 5 X aluminum alloy.
After seeing the Mohs hardness of 12, Li Fanyu couldn't close his mouth.
"I'm rich!"
Dare you imagine an aluminum alloy with a hardness beyond diamond? !
Even if it is not produced directly from the super material laboratory, it is not mixed with the mysterious X element, but it is produced by the exchange process. Subtracting 10% of the mechanical properties, the hardness of No. 5X aluminum alloy will reach a terrifying 10.8! ——This is still harder than diamond!
What does this performance mean?
The simplest example; airplane!
The aircraft body requires a large amount of aluminum-magnesium alloy and even aluminum-titanium alloy materials, which are connected with the mechanical structure to form the fuselage frame.
However, when an aircraft is flying or maneuvering at high speed, the force exerted by the air on the fuselage is too great, so a large amount of high-strength aluminum alloy is needed for the fuselage.
But this will increase the weight of the fuselage.
But what about using X aluminum alloy with higher strength?
Regardless of the variable dynamics structure, ordinary aluminum alloy parts need to be manufactured with a width of ten centimeters. X aluminum alloy can be made with only two or three centimeters!
What does this mean?
Lose weight! Reduce fuel consumption!
This can also be used for cars.
The simplest example is a front-engine model. If the engine is made of X aluminum alloy, it can greatly reduce the weight and size without affecting the performance, which will be of great benefit to the front and rear weight ratio of the car! Reduce fuel consumption and greatly improve operational feel!
To put it another way, instead of doing these high-tech things, just apply this material to the most common electronic devices in people's lives, such as mobile phones.
What if this material was used to make a mobile phone case?
You know, external factors are not considered. The main culprit of scratches on your phone is the tiny gravel in your pocket! What are the main components of these sand and gravels?
Silica!
The average Mohs hardness of silica is 7, which is a complete **** compared to No. 5X aluminum alloy!
If I could use this thing to make a mobile phone case, my mother would never have to buy a mobile phone case for me again!
Of course, using such high-end materials on mobile phones is definitely overkill.
Just when Li Fanyu was almost dancing with excitement, there was another bang in his head.
The cold mechanical sound of Xapp sounded again;
"Tip: It is detected that the current user has upgraded all X application levels to the highest level that can be upgraded, and the pre-upgrade tasks are completed."
"Tip: Xapp has been upgraded and the current level is 7."
"Tip: Design Specialization [Elementary] has been unlocked, please check it in the system space as the current test user."
"Prompt: You have a chance to draw a lottery, do you want to do it immediately? Yes/No"
Li Fanyu said: Huh? Design expertise?
What the hell! ? Skill type?
