1.Brief introduction

Barium tungstate is white powder, has micro toxicity. Relative density is 5.04. It can slightly dissolve in water, completely dissolved in oxalate water solution, decompose in acid and is stable in the air.

There are four preparation methods of tungsten alloy balls, namely, compression molding, disc pelletizing, squeeze-cut rotation method and injection molding.

1.Brief introduction

Block infrared rays at 950nm (up to 95% at 1400nm), mainly used for various plastic and glass films.

The low-temperature ductility of the tungsten wire is the main factor affecting the winding performance. The main influencing factors are the purity of raw materials, additives and the surface condition of the wire.
