Tungsten is a chemical element with the chemical symbol "W" and atomic number 74. In industrial and scientific applications, tungsten is often found in different forms and alloys rather than as a pure element. Tungsten alloy has high melting point, high density and good high temperature resistance, so it is widely used in many fields, such as electronics industry, aerospace, medical equipment and so on.
Tungsten alloys are usually represented by a series of grades and specifications to describe their composition, properties and applications. Some common tungsten alloy grades include:
Tungsten-Molybdenum Alloy: For example, Tungsten-Molybdenum alloy can be designated by the designation "TZM", which is an alloy of tungsten, molybdenum, zirconium and titanium, which has good heat resistance and mechanical properties.
Pure tungsten: Pure tungsten materials are usually indicated by "W", but in some contexts, the designation "WP" (such as WP-1, WP-2) may also be used to indicate tungsten materials of different purity.
Tungsten Copper Alloy: This alloy is used in electronic packaging and thermal conductivity applications. Common grades are "CuW" and "WCu", which represent different ratios of tungsten-copper alloys.
Iron Tungsten Alloy: This alloy is used in high density applications such as weights and vibration absorbers. Common grades are "FeW".
Other Tungsten Alloys: Besides the above alloys, there are many other types of tungsten alloys, each with different grades and applications.
It should be noted that different manufacturers and countries may use slightly different naming conventions, so it is best to refer to specific specification sheets and requirements for the exact grade and properties of the tungsten alloy being used in a specific application.
