Regardless of the fact that Badia and Park Chol-min are commercial counselors or senior trade representatives, although they are important in ordinary countries, they are not important to the extent that they are important, but in Iran and North Korea, they are much more important than in ordinary countries.

There is no way, whoever has let these two countries have been subjected to sanctions by a large country outside the region, and many urgently needed things cannot be obtained from normal trade channels, so they can only rely on commercial counselors or senior trade representatives to collect them all over the world.

Because of this, Badia and Park Zhemin are much more knowledgeable than officials of the same level in ordinary countries, especially when it comes to sensitive missile materials or core components, which can always stir the nerves of the two of them.

So when they found out that the triangular cube with metallic luster in their hands was actually welded with third-generation aluminum-lithium alloy, they were immediately not calm, and their eyes widened wider than the other.

Especially Badia, a pair of copper bell-sized eyes are bulging, and they almost pop out of their sockets.

Park Cheol-min didn't get much better, his hand dragging the triangular cube was shaking all the time, and he didn't know that he thought he was suffering from hemiplegia.

Other people in the cabin felt very surprised when they saw this scene, although aluminum-lithium alloy is specially used in aerospace manufacturing, it is rare on the market, but it is not a rare thing.

Even if the third-generation aluminum-lithium alloy has a performance that surpasses the previous generation, it is surprising that China can make it, but it has not reached the point of jumping eyeballs and shaking hands.

It is true that this is true, not to mention the third-generation aluminum-lithium alloy products, even the fourth-generation and fifth-generation products are at most surprising to Badia and Park Zhemin, and they are by no means like they have lost their souls.

The reason why this is so, without him, is only because the triangular cube made of aluminum-lithium alloy in his hand is engraved with a logo that hits their soul:

In the middle is an artistic variant of the letter "T" that resembles a falling arrow, followed by a dash, followed by two striking two letter combinations: NB!

T—NB！

A new king that swept the underground market of international aviation and aerospace high-end materials in this half year.

As soon as it appeared, it defeated the high-end aviation materials that had been entrenched in the international underground market for many years with its excellent performance, low price and sufficient cargo volume, and instantly occupied the high-end aviation materials market in Iran, North Korea, Pakistan, Libya, Algeria and even New Delhi and other countries.

There is no way, these countries are all regional powers, and even some countries are subject to various sanctions and restrictions, and out of practical needs and geopolitical security considerations, these countries very much want to be able to master long-range missile or launch vehicle technology, so that they can have self-protection in the future development.

But the problem is that these countries have great ambitions and high spirits, but their own foundation is fundamental, and they cannot achieve the complete matching of such high-end aerospace products, so they can only set their sights on the international market.

If it is an ordinary product, it is nothing, and the technology, materials and even processing equipment used for long-range missiles and launch vehicles can be said to be too much, especially Western countries, for various reasons, have formulated a whole set of restrictions and entry thresholds, and these things are strangled to death, and they should not be obtained at all under normal channels.

Since normal channels cannot be obtained, there are still large needs such as Iran and North Korea, so underground trade hidden under normal channels has emerged.

The reason why a major foreign country has imposed various restrictions on launch vehicle technology and designed a series of rules has not been able to lock in the breakthroughs made by regional powers such as Iran and North Korea in carrier rockets again and again, and the reason is that the underground trade channels under these rules continue to provide all the needs of regional powers like Iran and North Korea.

Among them, Merlintz, a senior engineer of Fairchild Aviation in the United States who signed a large order for the supply of Iridium supporting parts with Ascendas Group not long ago, is the most well-known.

Yes, the T-NB series of high-end aviation materials that have flourished in the international aerospace underground trade market in the past six months were launched by this American supplier.

Due to the closure and confidentiality of the underground trade market, the T-NB series of high-end aviation materials do not have any information about the origin and manufacturer except for a highly personalized logo and the corresponding brand of related materials.

However, this does not prevent the excellent performance of T-NB series high-end aviation materials.

Regardless of others, take the third-generation aluminum-lithium alloy as an example, before the T-NB series came in, Iran and North Korea only spent a high price to get the second-generation aluminum-lithium alloy at most, and only used it in key places with special savings when it was returned to China.

However, even so, the scrap rate of more than 60% still makes Iran, North Korea and other countries painful.

There is no way, although the second-generation aluminum-lithium alloy from the United States or Russia has made progress in welding performance, but there are many restrictions in actual operation, and many countries like Iran and North Korea do not have the unique processing technology, so that even if it is forcibly welded, the final test rocket will not hesitate to blow up to you.

Helplessly, Iran, North Korea and other countries can only choose to use the traditional riveting method to deal with this kind of second-generation aluminum-lithium alloy, which virtually increases the total structure of the rocket, resulting in a significant reduction in the carrying quality and effective range.

The three generations of aluminum-lithium alloy of T-NB are different, although the welding method only restricts several special welding methods such as tungsten argon arc welding or vacuum electron beam welding with gas protection, at least this material can be directly welded, which is a blessing from heaven for Iran, North Korea and other countries that lack advanced material treatment equipment.

So much so that when the sample was taken back to get the test results, he did not hesitate to wave the banknote and buy it tons and tons.

Even if the black-hearted supplier of Merlinz raised the price to 360 US dollars \\ kg, it could not stop the enthusiasm of Iran, North Korea and other countries to rush to buy, no way, T-NB's third-generation aluminum-lithium alloy is more expensive, and the yield rate is low;

Of course, these countries have not guessed the origin of this brand's products when they buy T-NB products back, and one of the most popular theories is that a large country outside the region produces its own products, but in order to hide people's eyes, it is just to engage in this nondescript T-NB brand.

Although Iran, North Korea and other countries are suspicious, they are still willing to believe that the T-NB series of high-end aviation materials come from a large country outside the region, the reason is very simple, in addition to the only superpower in the world, who else can provide so many high-end aviation materials on such a large scale?

Outcome......

"I use the high-end aviation materials I produce for the high-end regional airliners I produce...... What's the matter?

Zhuang Jianye looked at Badia and Park Zhemin, who were full of horror, and showed a playful smile......

......

"Yes...... Mr. Fang, that's the situation...... Our Group ......"

Just when Zhuang Jianye took the TRJ-500 towards the southern foot of the Qinling Mountains, Lin Guanghua, Peng Chuan and others were receiving Fang Yong, a member of the party group, deputy general manager and chief engineer of the Northwest Aviation Plant, in the new factory area of Tengfei Group located at the southern foot of the Qinling Mountains.

However, when Lin Guanghua introduced the overview of the new factory area of Tengfei Group, a staff member anxiously ran over and whispered two sentences in Lin Guanghua's ear.

"What? Brazilian guests? Have we been in contact with Brazil?"
