99.95% Pure Tungsten Boat

Tungsten Evaporator Boat use

Tungsten boats are widely used in vacuum coating industries such as gold plating, evaporators, video tube mirrors, heating containers, electron beam painting, household appliances (shells), mobile phones, toys, and various decorations, as well as in the sintering furnace sintering or vacuum annealing boat industry. middle.

In an ideal (vacuum, dry) state, connect the wires at both ends of the tungsten boat and energize, place the low melting point metal in the middle recess, and when the temperature rises below 2000 degrees, the metal will evaporate into gas, and the on the workpiece surface.

99.95% Pure Tungsten Boat

1, 99.95% pure tungsten boat application: suitable for inert gas arc welding and plasma welding, cutting, spraying, melting electrode.

2, 99.95% pure tungsten boat product features: high melting point, stable arc, no self-consumption. Add 0.15-4% Th02, Zr02, La02, Ce02 to tungsten, reduce the burning loss of tungsten electrode, make its life longer, do not pollute the weld: increase the electron emission capacity of tungsten electrode, make its arc starting current, arc stable current, arc starting gap, arc breaking gap, so the quality of the weld is high.

3, 99.95% pure tungsten boat export tungsten electrode IS06848 international standard and American standard AWSA5.12 and other standards, the chemical composition of the main tungsten electrode is shown in Table 5, flatness: not more than 0.5% of the length of the electrode.

4, 99.95% pure tungsten boat surface quality: smooth, clean, no defects (cracks, cracks, peeling), no oil and other impurities.

5, 99.95% pure tungsten boat electrode end face should be neat, smooth, no burrs, no internal defects (loose, impurities) section.
