USE

Molybdenum and metal alloys play an important role in the manufacture of weapons, as well as in cutting-edge fields such as missiles and rockets. In addition, tungsten wire is used to make filament, heating element of high temperature electric furnace. Molybdenum metal is easy to process into wire, tape, sheet, rod, etc., which is widely used in the electronics industry. Molybdenum wire is used as a small hook to support the heating wire in the light bulb, the gate of the electron tube, etc. Molybdenum, tungsten boat (vacuum coating)

NATURE

Tungsten and molybdenum two elements in the same column of the periodic table. They also exhibit the same properties. The average concentration of two elements in the Earth's crust is 1.5 parts per million. Molybdenum is an essential nutrient for plants and animals. At high concentrations, molybdenum can cause poisoning which is sometimes the case from alkaline ash leachate. Tungsten is an important strategic metal that is used in a variety of industrial applications. It is usually mined from scheelite, powder CaWO4, optical channel wolframite (iron, manganese) WO4. Tungsten is released into the environment, for example through its use in winter tires and ammunition. In general, the environmental behavior of tungsten is not well known

APPLY

Tungsten molybdenum alloy containing 30% tungsten (mass) has excellent resistance to the corrosion of liquid zinc, and is used to manufacture agitators, pipe and container linings and other components in the zinc industry. Tungsten molybdenum alloy due to high temperature strength, performance and tungsten similar to the specific gravity is smaller than tungsten, so it can be used as the corresponding high temperature conditions in the rocket, missile high temperature components, electronic tube filament, parts and other high temperature materials.
