Forging Tungsten Crucible 603

Forging tungsten crucible is referred as to the tungsten crucible that is manufactured by forging process, which mainly consists of three steps – blank preparation, forging and machining. Its density is generally greater than 19.0g/cm3, which almost reaches the theoretical density. While its diameter is usually less than 100mm. The tensile strength and high temperature deformation resistance of tungsten crucible produced by forging method are better than that of tungsten crucible produced by other methods. Producing Process of Forging Tungsten…

Coiled Filament 616

Coiled filament can be used for the production of incandescent lamps, with single helix type, double helix type and other types. Why coiled filament is applied for producing incandescent lamps? Here are some reasons: 1. The filament is very thin so that it is fragile if it is working under high temperature for a long time. While the helix structure can play a role of buffer to prevent it from breaking under vibration. 2. Light is emitted from the incandescent…
