Filament Classification
Jan 04, 2019

A widely used light source that emits warm, dim light, which is what most of us think of. It's cheap, so tungsten filament bulbs are also available in a variety of styles to match different fixtures. However, tungsten filament bulbs do not last long and do not save electricity. They also emit a low temperature, so they should not be too close to paper, textiles or silicone products.

W91 type tungsten wire is suitable for the manufacture of filaments, impact resistant filaments and other high temperature resistors.

W71 type tungsten wire is suitable for the manufacture of lamp filaments and other anti-shock devices.

W61 type tungsten wire is suitable for manufacturing spiral coil filament.

W31 type tungsten wire is suitable for making spiral filaments such as incandescent lamps.

W41 type tungsten wire is suitable for the manufacture of retained tungsten wire and tungsten heating elements.

W42 type tungsten wire is suitable for the manufacture of retained tungsten wire, tungsten heating elements and other equipment without special temperature requirements.

W11 type tungsten wire is suitable for the manufacture of electrodes and lead.
