As a metal with a high melting point, tungsten is widely used in high-temperature smelting, single crystal growth, vacuum evaporation and other industrial fields due to its excellent thermal stability, corrosion resistance and high strength. 

In the vast field of materials science, tungsten-nickel-copper alloy (W-Ni-Cu) shines like a brilliant star, exuding unique charm. As a high-performance material with tungsten as the matrix and alloying elements such as nickel and copper, it is known as the "versatile player" in the industrial field, playing an indispensable role in many key industries. From the high-tech aerospace sector to the manufacturing of daily electronic devices, its presence is ubiquitous. Let us now delve into the wonderful world of tungsten-nickel-copper alloy, exploring its composition, unique properties, and extensive applications. 

Tungsten crucibles play an important role in high-temperature metallurgy, crystal growth, vacuum smelting and other fields, and have long been known for their excellent high temperature resistance and good chemical stability. 

Tungsten-nickel-iron alloy is an important tungsten-based high-density alloy. By definition, it is an alloy composed of adding nickel and iron to metallic tungsten, with the nickel-iron ratio typically maintained at 7:3 or 1:1. With excellent comprehensive properties, this type of alloy is widely applied and has become the main category of tungsten-based alloys with large usage at present.
