In our production live, tungsten spheres have many important effects on us and are widely used in various fields such as making water meters, flow meters, making pens, and so on. So what are the advantages of tungsten spheres? Let's take a look.
The following is a list of contents:
l Characteristics of tungsten sphere
l Properties of tungsten sphere
l Applications of tungsten sphere
Compared to lead, tungsten spheres are non-toxic, non-polluting, and safer. The high density of tungsten alloy allows tungsten sphere to maintain their shape even in extreme environments. That is why they are also processed as a tungsten ball bearing.
Among the metals, tungsten has the highest melting point, high-temperature strength, and creep resistance as well as thermal, electrical, and electron emission conductivity, and high specific gravity. In contrast to depleted uranium, which has a density similar to that of tungsten alloys, depleted uranium is radioactive and requires special permits for radioactive materials, making its use difficult and costly. Therefore, more often than not, people choose to use tungsten spheres, which are safer and have a similar density.
Physically, tungsten spheres have a metallic luster, a hardness similar to diamond, excellent electrical and thermal conductivity, and low electron escape work. Melting point 2870℃, boiling point 6000℃, relative density 15.63(18℃). In the air at room temperature, it is very stable and only slightly oxidized at 400℃.
Chemically, tungsten spheres are insoluble in water, hydrochloric acid, and sulfuric acid, but are easily soluble in nitric acid-hydrofluoric acid mixture. If a small amount of titanium, cobalt, and other metals are mixed in the preparation process, it can reduce its brittleness. Sometimes also often add titanium carbide, tantalum carbide, or a mixture of them to improve the tungsten sphere's ability to resist explosion. Tungsten is chemically stable, and in tungsten carbide balls, carbon atoms are embedded in the gaps of the tungsten metal lattice and do not destroy the original metal lattice, forming a gap-filling solid solution, also known as gap-filling (or insertion) compounds.
Carbon is generally added to form tungsten carbide balls, and the carbonized tungsten is suitable for mechanical processing at high temperatures. It is chemically stable and does not interact with hydrochloric acid or sulfuric acid even under heating conditions, is not even dissolved in aqua regia, ranks high in hardness among metals, and can only be pressure processed when heated to very high temperatures.
Therefore, tungsten spheres are widely used in water meters, flow meters, pen making, precision hardware, valves, molds, bearings, die castings, punches, fishing gear, counterweights, and other fields, just because of their resistance to wear and tear, high temperature, not easy to corrode, and high hardness.
