[QUOTE="Deleted member 46119, post: 1292661"] Copper–tungsten From Wikipedia, the free encyclopedia Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy. The material combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine. Parts are made from the CuW composite by pressing the tungsten particles into the desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods, and bars of the composite mixture are available as well. Commonly used copper tungsten mixtures contains 10–50 wt.% of copper, the remaining portion being mostly tungsten. The typical properties is dependent on its composition. The mixture with less wt.% of copper has higher density, higher hardness, and higher resistivity. The typical density of CuW90, with 10% of copper, is 16.75 g/cm3 and 11.85 g/cm3 for CuW50 . CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50. Is this the holly grail we are looking for. It's what I described earlier a heavy non-toxic sintered and infused to form a matrix. Common materials, deformable, net density increase from lead. The only drawback is developing the manufacturing process to reduce expense. This process is even at a level where an experimenter/inventor level entrepreneur could have a go at making projectiles. Density of lead is 11.34 g/cm3 Density of %50 copper %50 tungsten is 11.85 This has promise. There are even tungsten powder kits you can buy. With the sintering process the shape of a core does not have to be the same as a lead core. things that improve gyroscopic stability. Fun stuff. Now if I just had unlimited money. [/QUOTE]
