Tungsten Filament Wire Makes Incandescent Light Bulbs Safer and Brighter 2,836

Incandescent light bulbs have been making homes safer and brighter for over 100 years. After centuries of using fire, candles, oil lamps and gas, the invention of the incandescent light bulb transformed everyday life. Tungsten is the material of choice for this innovation, emitting bright and long-lasting light. In 1904, a Hungarian company produced the first tungsten wire, and then in 1906, General Electric managed to make a ductile tungsten wire. The wire made of tungsten is very fragile, which…

Type and Application of Cemented Carbide 3,053

There are three types of cemented carbide with wide application. It is a kind of alloy material made by hard compound of refractory metal and bonding metal through powder metallurgy technology. It has excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. Especially, its high hardness and wear resistance remain basically unchanged even at 500℃and still have a very high hardness at 1000℃. There are three kinds of alloys including tungsten cobalt…

Preparation Method of Ultrafine Grain Tungsten Carbide 404

Ultrafine grain tungsten carbide is a kind of cemented carbide made up of tungsten carbide (or other carbide) powder less than 0.3µm and cobalt bonded phase. With the decrease of WC grain size, the toughness and hardness of the cemented carbide can be improved. Because the WC grains become smaller, the high dispersion of the cobalt bonded phase is increased, and the WC grains are more evenly dispersed among the cobalt bonded phases. The hardness at high temperature and compressive strength at room…
