Tungsten is the most refractory metal of all. This material is a wide variety of products ranging from household appliances and jewelry, ending — parts for nuclear boilers and modern missiles.
It is an indispensable element of the bulb. The more current, and, accordingly, the temperature of the spiral, the greater the light output. When this occurs, the evaporation of tungsten, which leads to the thinning of the filament. To reduce evaporation, the bulb is filled with inert gas. Øвольфрамовой spiral in the bulb is a fraction of a millimeter, the length of the helix 5, see When you turn on the light bulb in the network voltage of 127 Volts through the spiral flowing current of 0.31 A. In modern electrical engineering of the tungsten filament produce the cathode and the filament in the lamps, television tubes and other vacuum tubes.
Such rings are durable, resistant to wear, yet look no worse than the rest of the decorations. Tungsten has the same specific weight as gold, polished, looks very attractive. With different resistance to stress, to the action of aggressive factors, does not tarnish with time. We offer stylish men’s and women’s rings made in a variety of techniques of cutting and inlay with a matte or mirror surface, gold-plated and blackened, decorated with ornaments.
