In modern welding technology, non-consumable electrodes play an extremely important role in high-quality welding processes, especially in application scenarios such as tungsten inert gas welding (TIG), where the performance of electrode materials directly determines the stability, efficiency and quality of welding.

In the vast field of materials science, high-density tungsten alloys stand out due to their unique properties, becoming a focal point across numerous industries. Tungsten alloy is a material with tungsten as the base (W content 85-99%) and small amounts of elements such as Ni, Cu, Co, Mo, and Cr added. Its density ranges from 16.5 to 18.75 g/cm³, more than double that of steel, making its remarkable high-density characteristic a key factor in its wide-ranging applications.

In the vast world of sports, from the rigorous training of professional athletes to the daily fitness routines of the general public, various sports equipment play a crucial role. Among these, there is a component often overlooked yet vital—the counterweight. Like an unsung hero behind the scenes, it silently contributes to the high-performance capabilities of sports equipment. For instance, in fitness dumbbells, improper counterweighting can not only affect workout effectiveness but also lead to injuries; similarly, in golf clubs, the right counterweight can enhance shot precision and power. Today, let’s delve into a standout counterweight material in the sports field—tungsten alloy counterweights.

Tungsten-copper (WCu) contacts, like tungsten-silver (WAg) contacts, are highly representative types of tungsten contacts. The reason their physicochemical properties, production methods, and applications are largely similar lies in the fact that both are manufactured using the refractory metal tungsten as a base. However, there is a cost difference between silver and copper, with silver generally being more expensive than copper.
