We usually buy bolts, whether on the Internet or in stores, we find that bolts are very cost-effective. We can buy a big bag of bolts for a few yuan. However, when we search the price of bolts for aircraft carriers, we will feel a chill in our hearts. Why do we have such expensive bolts? Is it very expensive because it is produced by state-owned enterprises under the monopoly of the industry? Or is it expensive because it sounds high-end? In fact, it's not that you can get what you pay for. It's henggu's rule that hasn't changed so far. Therefore, the cost of aircraft carrier bolts is undoubtedly due to the increase of its cost. Let's master which aspects of the cost increase.

First of all, aircraft carrier bolts are different from ordinary bolts. In order to better ensure that custom-made lantern rivets are not easy to deform and mildew in various extreme natural environments, a kind of titanium metal called "space metal material" must be selected. This kind of metal material is resistant to high temperature, corrosion, can bear great impact, and its own price is expensive. In addition, it is used in aviation The above Mothership has to go through some unique solutions, which also increases its price. Therefore, it is more expensive.

Secondly, because bolts are used for aircraft carriers, in addition to tightening mechanical equipment, they must also be given some unique functions. Therefore, we must have a very high level of technology. China has invested a lot of money in the research and development of high-tech products, in order to better the aircraft carrier to shoulder the burden of defending the motherland in the future unpredictable and analyzed war, Every moment of automotive rivets are the wisdom of scientific and technological personnel for two years or even decades. Therefore, expensive is a big reason.
