As leading tungsten alloy manufacturer, we would like to give you a brief introduction of our technology. Powder Metallurgy comprises a family of production technologies, which tungsten alloy process a feedstock in powder form to manufacture components of various types. These production technologies generally involve all or most of the following process steps:
1. Powder production
2. Mixing of powders. This can often involve the introduction of alloying additions in elemental powder form or the incorporation of a pressing lubricant.
3. Forming of the mixed powder into a compact. The dominant consolidation process involves pressing in a rigid toolset, comprising a die, punches and, possibly, mandrels or core rods. However, several other consolidation processes are several other consolidation processes that are used in niche applications.
4. Sintering of the form to enhance integrity and strength form. Tungsten alloy manufacturer process step involves heating of the material, usually in a protective atmosphere, to a temperature that is below the melting point of the major constituent. In some cases, a minor constituent can form a liquid phase at sintering temperature; such cases are described as liquid phase sintering. The mechanisms involved in solid phase and liquid phase sintering are discussed briefly in a later section.
5. Secondary operations. The application of finishing processes to the sintered part. In the powder metallurgy industry, such processes are often referred to as "secondary operations".
The majority of current uses for WHAs (tungsten heavy alloy) are best satisfied with the W-Ni-Fe system. Alloys such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe alloy is a common approach for slight enhancement of both strength and ductility. The presence of cobalt within the alloy provides solid solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction are most common.
As to be special properties and special tungsten alloy manufacturer, tungsten alloy material is usually used for tungsten alloy radiation shielding, tungsten alloy crankshaft, tungsten alloy counterweight, tungsten alloy fishing sinkers, etc.
