As we all know, Tungsten Cylinder Counterweights have comprehensive properties such as high melting point, high density, high strength, low thermal expansion coefficient, corrosion resistance, and good mechanical processing, and are widely used in aerospace, military equipment, electronics, chemical industry, and many other fields.
Here is the content list:
l Properties of Tungsten Cylinder Counterweighs
l Key Features of Tungsten Cylinder Counterweights
l Application of my country in Tungsten Cylinder Counterweights
Tungsten Cylinder Counterweights are usually refractory metals, generally composed of W-Ni-Fe (tungsten-nickel-iron) or W-Ni-Cu (tungsten-nickel-copper) or W-Ni-Cu-Fe (tungsten-nickel-copper- Iron), some Tungsten Cylinder Counterweights also add Co, Mo, Cr, etc. They have high melting points, are twice as dense as steel, and are 50% heavier than lead. The content of tungsten in the alloy is usually 90%~98%, which is why Tungsten Cylinder Counterweights can have a high density (usually 16.5g/cm3~18.75g/cm3). Ni, Fe, and Cu are used as binders to hold the brittle tungsten together, thereby enhancing the ductility of Tungsten Cylinder Counterweights and making them easier to process. Ni-Fe is a commonly used additive, and its ratio is 7Ni:3Fe or 8Ni:2Fe (weight ratio). The usual production process for Tungsten Cylinder Counterweights includes compounding, cold pressing, and liquid phase sintering until the desired density. In liquid phase sintering, this base alloy is in a molten state, which helps Tungsten Counterweight dissolve better with the liquid so that large tungsten particles (20-60 microns) are dispersed in this base alloy. The sintered material is usually subjected to a thermomechanical treatment process, such as forging, to increase its hardness and strength. At present, the composition of Tungsten Cylinder Counterweights is W-Ni-Fe, which is very popular. Adding an appropriate amount of cobalt to the W-Ni-Fe alloy can enhance its strength and ductility.
Tungsten Cylinder Counterweights have many special properties, such as small size but high density (usually 16.5 g/cm3~18.75 g/cm), high melting point, high hardness, excellent wear resistance, high ultimate tensile strength, ductility good properties, low vapor pressure, high-temperature resistance, good thermal stability, easy processing, corrosion resistance, good shock resistance, extremely high radiation absorption capacity, excellent impact resistance and crack resistance, and non-toxic and environmentally friendly, and the Tungsten Cylinder Counterweights standards required by international environmental protection are consistent.
Tungsten Cylinder Counterweights heavy alloy has a series of excellent properties, so it has been widely used in the national defense industry, and it has also been widely used in the large-scale and wide-ranging civil industry. My country is also a country with large tungsten resources. There are also many research and production test units for China Tungsten Weight, and the Tungsten Counterweight developed in my country can reach more than 20 varieties.
