Pure copper!Zhang Heng's copper content is 99%, not the pure copper that is casually called out on the market.The pure copper on the market is a joke if it has a copper content of 30%!As for the waste copper used in copper-zinc alloy, the copper content is even less."Hehe... I think the 50 tons of pure steel brought back from the Ordnance Group will definitely not be willing to be used to dilute bullets and shells? After all, it contains 99% copper, which is very rare and will be used where it is most needed."Zhang Heng smiled across the air and turned his eyes back to the yard: "If it is not compressed into a plate shape, these 33,800 tons cannot be put away!"Before asking about the composition ratio of this batch of copper-zinc alloy, it is impossible to roughly estimate the value.It can only be put aside for the time being.Focus all attention on the great cause of assembling cars.As the saying goes, once is new, twice is familiar, and as expected, the assembly speed is much faster.This time, the SUV is assembled, and the domestic extended version of the car will be assembled last.After two days of hard work, the SUV has been assembled for more than two-thirds, but it is time to stop.Have a good night's sleep!The next morning, after breakfast, I drove the cool supercar towards the city.Modern technology is developing rapidly, so fast that people are a little overwhelmed.A few years ago, it was impossible to be as convenient as it is now, but now? Even if you don't know the way, you just need to turn on the navigation, and the navigation will take you to the exact location, without you having to hold a paper map, then identify the direction reference, and then find the location.More than 60 kilometers of journey!In the middle, I got on the highway, and I could step on the accelerator to more than 100 miles, and it took just over an hour."Comrade...""Hello, I'm Zhang Heng from Hengyuan Mining Group!"Zhang Heng didn't bump into the guards. The guards were sacred and inviolable. He parked his supercar and walked over: "I'm here to see Major Qin. I have something to say about cooperation with Northern Ordnance Group.""Oh..."The guard was unmoved. He looked at Zhang Heng for a long time before saluting again: "Please wait!"Call the inside from the gate to inquire about the situation and then decide whether to let him in."Comrade, Major Qin asked you to wait here for a while!" The guard called back."Okay!"Zhang Heng smiled and didn't refuse. He didn't let him go in directly, but waited for someone to pick him up. It sounded like Major Qin came out to pick him up in person, which was considered to be giving him enough face.It was about ten minutes.A warrior drove out. It was Major Qin. Someone came to pick him up. He didn't even need to register his ID card. He went in directly. It wasn't a special treatment, but someone guaranteed him.The reception room of the office building looked much more formal."Major Qin, I won't be polite. Originally, I could contact the Ordnance Group directly, but this time I came here for more than one thing, so..."Zhang Heng got straight to the point and brought a lot of things. He first took out a document from his briefcase and pushed it to the other side: "This is a test report of copper-zinc alloy, and... there is also a copper-zinc alloy.""Copper-zinc alloy was mentioned by the Ordnance Group last time. I have 33,800 tons on my hand.""In addition, there is 80 tons of pure copper of the same quality as last time."Zhang Heng was well prepared. He had paper test reports and brought samples. He could let people test it themselves and then compare it with the test report he showed to see if there was any difference: "I have to trouble you to contact the Ordnance Group.""Okay, I'll call right away!"Major Qin was resolute and decisive. He was only informed of the details after the last escort. As for the use of copper-zinc alloy, he came from a grassroots soldier and was not unfamiliar with it. To this day, he still deals with it every day: "Wait here for a moment, it will probably be quick.""Please wait..."Zhang Seeing that the other person was about to leave the reception room, Zhang Heng couldn't help but smile bitterly and stopped him: "There are other things. Why don't you wait until I finish, and then...""I guess you still have to report it to the higher level, and it may still need to be reported to the higher level, because this is relatively more serious and it also involves two relatively large departments." Zhang Heng added immediately."Okay, please go ahead!"Major Qin sat back down. I don't know if Zhang Heng's words were a bit solemn or something, he sat straighter and his expression became more serious.That's right!He just opened his mouth and said that he needed to report to the higher level, and there were two relatively large departments.It's not an ordinary matter, so there is no need to do this....
