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

To be honest, copper-coated steel bullets are not difficult for Su Hua.

Soon, Su Hua placed a small batch of copper-coated steel bullets in front of Chen Tianjue.

Chen Tianjue observed these copper-coated steel bullets carefully, then picked them up and weighed them in his hands, saying with surprise:"Comrade Su Hua, the copper-coated steel bullets you made feel almost the same as brass bullets!"

"I just don’t know how powerful this bullet is!

Su Hua:"It's very simple. You'll know after you try it, right?""

Then,

Chen Tianjue, Su Hua and others came to the shooting range of the arsenal and began to test the power of the copper-coated steel bullets.

Bang......snap... click......

The gun tester was very skilled in loading the bullet and pulling the trigger. da da da da......

Chuchuchu......

A flurry of bullets flew out and accurately hit the gun target 100 meters away. crackling......Wow......

The entire gun target was instantly beaten to pieces.

Broken everywhere.

Seeing such a scene, Chen Tianjue was overjoyed and said,"This copper-coated steel bullet is as powerful as a pure copper bullet!"

Then he began to test the hardness, ductility and other properties of the copper-coated steel bullet.

After some testing, we finally came to the conclusion that this copper-clad steel bullet is no different from a pure copper bullet, except that its ductility and lubricity are slightly worse than that of a pure copper bullet.......It can completely replace pure copper bullets.

This result made Chen Tianjue overjoyed and said:"Comrade Su Hua, after testing, the copper-coated steel bullet you invented can perfectly replace the pure copper bullet.......This helped us solve a big problem!"

"you don't know......Before you came up with this copper-coated steel bullet, our factory was still worrying about brass as a raw material!"

Due to its physical properties, the bullets produced by steel have low accuracy and are easily corroded and difficult to preserve. Most countries do not use steel for manufacturing.......Brass has good mechanical properties, strong ductility, and easy extraction, making it the best material for making gun bullet casings.

Therefore, all countries basically use brass to make bullets.

The same is true for May Day Arsenal.

However, with the massive consumption of the war, as well as problems with production technology and the difficulty of copper mining, the May Day Arsenal fell into a situation of lack of brass raw materials.

At present, Rabbit’s existing copper mines are mainly distributed in Tibet, Yunnan and Prairie Provinces. Due to terrain factors, resource extraction is difficult, and only about 25% of the mines are profitable.......In addition, among the 18 copper mines with a capacity of 10,000 tons or more, the average grade is only 0.75%.

It can be said that even when fully developed, Rabbit's copper resources are not enough to support the manufacture of large quantities of bullets.......Not to mention that there is currently no way to fully develop and mine copper mines, so there is a very shortage of brass raw materials.

This problem has always troubled Chen Tianjue.

After all, the war is not over yet.

Now Su Hua has completely helped him solve this problem. wrong.

Su Hua helped Rabbit's military industry solve this problem.

Su Hua:"Yes, factory director, if we all use copper-clad steel bullets, not only can we reduce costs, but we can also increase production efficiency and produce bullets in large quantities!"

Chen Tianjue said excitedly:"Comrade Su Hua, you just You have made a great contribution by coming to our factory! You have helped us solve a big problem!"
