Can a screw in an aircraft carrier really be traded for an Audi?

Because it has to be in the sea all the time, it needs special materials. As an important representative of the weight of a country, the aircraft carrier also symbolizes and reflects the comprehensive national strength of a country. First of all, not every rivet on a carrier is expensive, but it is. These sky-high rivets are made of titanium.

Titanium is a rare metal that is dispersed in nature and difficult to extract. It is characterized by light weight, good corrosion resistance, high strength, high heat resistance. It is because of its stable chemical properties, good high temperature resistance, low temperature resistance, strong acid resistance, so it is called space metal. The price is justifiably high.

In addition, its production process is very complex, the whole process can not have a link error, titanium alloy products if there is a fault in the production process, the whole batch of titanium alloy products will be all scrapped. At present, only China, USA, Russia and Japan can produce it, plus it is used on aircraft carrier, so for rivets is the best of them. Finally, Tutu said, the sky-high rivets are not only made of titanium alloy, but also coated with a layer of high-temperature resistant material.

Because of this, a titanium alloy rivet on a carrier can already cost around 500,000 yuan. It is not unreasonable to say that it can be exchanged for an Audi.

I remember General Zhang Zhaozhong once said in a program that a screw on the Liaoning can be exchanged for an Audi! And how many screws does a carrier need? And with screws at such a price, the cost of an entire aircraft carrier is worth a fortune. But are aircraft carriers really that expensive?

In fact, this is not entirely true. Take the Liaoning Aircraft carrier as an example. In fact, what Zhang Zhaozhong said was only a few screws, not all of which are so expensive. But it is only relatively speaking, because the aircraft carrier needs to stay at sea for a long time, so its particularity determines that the materials used are much more expensive than ordinary materials, so that they can be durable and durable.
