【chinatungsten】Tungsten dart advantage

The raw materials of tungsten tungsten dart is a very dense material, not easy to melt, and not easy to shape, usually ground into fine powder, then with other kinds of metal as the binder mixture. In the production of tungsten dart, mixing with the most commonly used copper and nickel, iron compounds and a small amount of. The mixture was heated and compressed into a solid steel or tungsten rod and then processed into a darts barrel.
After the special craft processing of tungsten dart heavy weight, high density, the aerodynamic effect is good, durable. The same weight of darts, tungsten dart advantages, its size (thickness) than other texture darts is much smaller, it will increase the possibility of dart cast in the same high partition.
