As we all know, depleted uranium alloy materials and tungsten alloy materials are manufacturing penetrators ideal materials at present, but looked from the world scope, tungsten alloy material both range applications or application state are relatively depleted uranium alloy is more extensive and widespread, especially in the Western European countries is mainly the development of tungsten alloy materials (British, law except). How should we develop for the two kinds of materials? In the author's opinion, the answer to this question can never escape from the national conditions and the military, by starting from the analysis of sources of raw materials, production cost, manufacturability and two kinds of material properties, compared to arrive at a conclusion.

Military material must be based on domestic rich and reliable sources of supply, this is our policy. From the current and expected future, tungsten alloy materials and depleted uranium alloy materials in our country have reliable sources. Tungsten both reserves or annual output of our country occupy the first place in the world, depleted uranium material is waste to produce nuclear weapons and nuclear fuel, at present our country also has a lot of, and no other use, can saying is the reuse of waste. Therefore, a reliable source of tungsten alloy materials and depleted uranium alloy materials in our country.

From the processing technology, both tungsten or depleted uranium alloy, at present our country in mining, smelting, processing and manufacturing technology level are more mature, compared with foreign tungsten alloy and properties can be depleted uranium alloy of these two materials. It also shows that the two kinds of materials in our country have the certain technology base, and the two kinds of materials exist at the same time continue to improve, the necessity and possibility of improvement. From a cost point of view, although the depleted uranium material cost is low, but the said materials processing, waste disposal, protection and high test cost, the final result is, tungsten and depleted uranium alloy two penetrators cost basic.

The U.S. currently almost all caliber gun and cannon part with depleted uranium penetrators, especially is equipped with 120 mm projectile by depleted uranium materials. Under its impetus, Britain and France also for domestic equipment main battle tank equipped with depleted uranium penetrators, while the British Lu Jun despite domestic opposition, repeatedly stressed: "Challenger" main battle tanks will never cancel the depleted uranium penetrator.

Depleted uranium alloy penetrators is made after the upgrade armor elastic energy trend of development, but not the only, because it involves a lot of trade-offs problem. So our country need to development of depleted uranium penetrator? In this issue, the author still emphasizes the problem of trade-offs. But in general, on the basis of the author's personal opinion, if it is to use depleted uranium penetrators to completely replace tungsten alloy penetrator words, will do more harm than good. This is because, at present, our army is not depleted uranium dedicated for military training with the projectile range, so the general in the army exercises and training can not be used; if long-term not encountered war, depleted uranium storage without and expired penetrator cannot be used as a useful metal back and forth, only be returned to the original production factory processing, not only the recovery of economic value, but is the addition of waste disposal costs. From these aspects, we should not be a large number of production and reserves of depleted uranium alloy penetrators.

But on the other hand, we must consider the development potential of depleted uranium penetrator and its unique advantages of target function. So, we are difficult to develop the depleted uranium alloy penetrator issues should adopt a positive and prudent attitude. The so-called positive, is to focus on certain energy and human choice (for example can choose the large calibre gun as the key point, such as 105, 125, or even pre research of larger caliber APDs) to depleted uranium alloy we penetrators up. Technically, this should not be what problem for us. The process of projectile in depleted uranium alloy development progress caliber in, to understand and to further tap the comprehensive performance of depleted uranium alloy penetrator, and on the basis of the accumulation of depleted uranium alloy penetrators to production, test, protection, storage and use of experience. The so-called prudent, refers to the penetrator performance in not fully understanding the depleted uranium alloy case, not rashly indiscriminately to all the attention. A more sensible approach is the development should be the principle of tungsten alloy materials mainly, supplemented by depleted uranium alloy materials, continue to dig the tungsten alloy penetrator potential on the one hand, on the one hand through the trial and small batch of continuous accumulation and rich manufacturing depleted uranium alloy penetrator experience. Needs to be pointed out is, the future research emphasis of depleted uranium alloys should be to further improve the metallurgical properties and development of depleted uranium alloy new composite materials (such as uranium alloy tungsten uranium alloy), make it more adapted to the penetrator large slenderness ratio requirements. At the same time, the structure design of projectile to make full use of this characteristic, the depleted uranium alloy penetrator power of tungsten heavy alloys was significantly better than that of the projectile, solve the tungsten alloy penetrator cannot deal with the target, but also the only way to make the depleted uranium penetrator with real life force in the nation, if able to do this point, in order to deal with the war in the future, can the adverse development of depleted uranium alloy mentioned penetrators when the side relegated to a secondary position, or even negligible.
