The latter is also the tail-stabilized shelling penetrator used on the third generation of modern main battle tanks (abbreviation: APFSDS) is one of the two main materials (the other is the notorious, highly radioactive depleted uranium penetrator core, The user country is mainly the United States, while China mainly uses tungsten alloy penetrators, Less pollution and better performance, The United States does not need to. First, the United States does not pass the standard of tungsten treatment technology. Far from the level of our country, Secondly, the United States is a tungsten-poor country. It also wants to fully use tungsten alloy bombs, But it can't be used, But as a nuclear Power, There is a lot of depleted uranium as nuclear waste, so depleted uranium is selected as a substitute.
