Model Rocket Engines & Tungsten

   Recently, I found that Some military weapons use rockets to propel warheads to their targets. A rocket and its payload together are generally referred to as a missile when the weapon has a guidance system (not all missiles use rocket engines, some use other engines such as jets) or as a rocket if it is unguided. Anti-tank and anti-aircraft missiles use rocket engines to engage targets at high speed at a range of several miles, while intercontinental ballistic missiles can be used to deliver multiple nuclear warheads thousands of miles, and anti-ballistic missiles try to stop them. 
     Tungsten is often used in military defense such as rocket owning to  its greatness and resistance to high temperature. If you want to know more details, please go to http://www.tungsten-alloy.com
