1.Advantages of tungsten alloy or tungsten carbide: ①High strength ②High thermal strength, can work for a long time at a temperature up to 750 ℃ ③Good corrosion resistance ④Good low temperature performance,tungsten alloy and tungsten carbide still maintain its mechanical properties in low and ultra-low temperature. Compared with the brass nozzle, it is harder and more wear-resistant, and has a longer service life.
