Compression was carried out of modified copper powder workpieces at a pre-determined value of the pressure. High temperature sintering of the workpieces in a neutral medium at a temperature of 1,000°C was performed. A high density metal-ceramic composite material was obtained. Its structure and physico-chemical parameters were determined. Lead-free prototypes were created, corresponding to the weight and dimensions of the reference standard lead passive elements for high energy impact.

  4. Tungsten has the highest melting point of all elements except carbon at 3,400o C with good high-temperature mechanical properties and the lowest expansion coefficient among all metals, with a density of 19.25 g/cc. It is among the heaviest metals. The name itself is of Swedish origin: tung (heavy) and sten (stone), in deference to the Swedish chemist/ mineralogist who first discovered and described the ore. It is also known as wolfram, which gives tungsten its chemical symbol, W. (Source: Tungsten Industries Association [London].)
