Military Industry: On the eve of the War against the Eagles, I am building nuclear bombs for the cou

Chen Tianjue quickly looked at Su Hua and asked:"Comrade Su Hua, please tell me......What can you do? Su Hua said slowly:"

Director, the body of our current bullets is made of brass."......This is not only costly, but also affects production efficiency......I think we could use copper clad steel! Even though he was an old man with a lot of military experience, Chen Tianjue didn't know what copper-clad steel was. He couldn't help but look puzzled and said,"Copper-clad steel?" What's this? Can it be substituted for copper?"

Nowadays, countries basically either use brass materials to make bullets, or use steel to make bullets. The reason why Western countries such as Europe and the United States commonly use brass materials is because this purple-red shiny metal has good ductility. , lubrication and air tightness.

It not only plays a lubrication role when the barrel and rifling rub, ensuring that the bullet can be fired smoothly without wearing the gun body.......Moreover, while being easy to manufacture, it can also be well wrapped to withstand the high-pressure and high-heat combustion of the propellant, allowing for a slight expansion and deformation.

Steel bullets have many problems......That is, when the bullet is fired, the high temperature will cause the cartridge case to expand, and the steel cartridge case cannot have as good ductility as copper.......The ballistic trajectory will be unstable during launch and the accuracy will be greatly reduced.......And it is easy to corrode and is easily damaged in humid environment.

Su Hua:"To put it simply, copper-coated steel is a steel bullet covered with a layer of copper!"

"Compared with pure brass bullets, copper-clad steel bullets are low-cost and have the same effect as pure brass bullets, so I think we can completely change the raw material of the bullets and use copper-clad steel."

"At the same time, the use of copper-clad steel can also improve the production efficiency of bullets."

Based on the 5.8mm universal bullet, the amount of copper-clad steel used in a 5.8mm universal bullet is 6.25g. One ton of copper-clad steel is enough to produce 160,000 bullets. The main material cost of a bullet is only 3 cents.......But if pure brass is used to make bullets, the main material cost of a single bullet is 4 cents.......This is a huge cost gap!

Chen Tianjue nodded slightly, and after thinking for a moment, he said:"Comrade Su Hua, let's do this.......First you can get some copper-clad steel bullets and show them to us.......Seeing is believing!"

"If you need our arsenal to cooperate with you, just ask! Su Hua:"

Okay, no problem!""

Because of the help of the god-level scientific research system, it is not difficult to make some copper-clad steel.

Afterwards, Su Hua went to the smelting department to get steel and brass, and began to operate the machine for mold opening, spraying, electroplating and other processes. The next step is to manufacture bullets and so on.

In just one day, Su Hua produced a batch of copper-clad steel bullets....

PS: A new book is open, this time it is more simple and crude......It's more exciting than the ak one, because you're dealing with Eagle Sauce......Lao Zhan promises that I will never let you down, but I still need your support.

I beg for free flowers, monthly tickets and evaluation tickets. If there is a 100VIP broken egg reward, then it will be even more motivation.

If there is a reward, 10 updates will be released immediately. I will do what I say, and I beg for all support.

If you are an old reader of mine, you should know: the previous military-industrial article"The War of Resistance: Full Level Comprehension, Starting with Hand Rubbing AK" was mainly for fighting Japanese invaders, but now this military-industrial article is for fighting hawks, all kinds of advanced military industries are flying together, You will definitely not be disappointed, the plot is absolutely wonderful.

Now I just beg for all the data support, thank you.
