How Does Different Lanthanum Contents Affect Tungsten Electrode Performance? 7

In modern welding technology, the choice of electrode material directly impacts welding quality, efficiency, and equipment stability. As a key consumable widely used in TIG (tungsten inert gas arc welding) and plasma cutting, tungsten electrodes, due to their high melting point, excellent conductivity, and ablation resistance, have become a vital component in industrial manufacturing. In recent years, with increasing demands for environmental protection and welding performance, electrode materials doped with rare earth elements (such as lanthanum) have gradually replaced traditional…

Exploration of Tungsten Alloy Application Fields 19

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. From a microstructural…

What Is Tungsten-Copper Contact? 36

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. Tungsten-copper contacts (Tungsten Copper Contact) are electrical contacts made with tungsten as the base material and copper as the auxiliary…

What Is Silver Tungsten Contact? 35

Tungsten contacts are a type of electrical contact material, with their primary chemical composition including the refractory metal tungsten along with copper, silver, and other metal elements. They exhibit excellent thermal, mechanical, and electrical properties, making them widely used in the power sector. Depending on their chemical composition, tungsten contacts can be classified into tungsten-copper (WCu) contacts and Silver Tungsten (AgW) contacts. Silver Tungsten contact is materials formed by combining silver and tungsten, characterized by a structure where tungsten serves…

What Is Tungsten Alloy Rod? 24

Tungsten-based alloys can be categorized into different types—tungsten alloy rods, tungsten alloy blocks, tungsten alloy plates, and tungsten alloy spheres—based on their external shapes. These alloys share similar physical and chemical properties but differ in their specific applications. Tungsten alloy rods, also known as tungsten bars, are alloy products made with refractory metal tungsten as the hard phase, supplemented by metal elements such as cobalt, nickel, iron, and copper as binding phases. Leveraging their excellent physicochemical properties, they are widely…

Tungsten Alloy Rod 26

Depending on their shapes, tungsten-based alloys can be categorized into tungsten alloy rods, tungsten alloy blocks, tungsten alloy plates, and tungsten alloy spheres. While their physicochemical properties are generally similar, their applications differ. Taking tungsten alloy rods as an example, also referred to as tungsten bars, they are alloy products with refractory metal tungsten as the hard phase and metals such as cobalt, nickel, iron, or copper as the binding phase, known in English as tungsten bar. In terms of…

Tungsten-Copper Contact 33

Like tungsten-silver (WAg) contacts, tungsten-copper (WCu) contacts are also a typical type of tungsten contact. Since both tungsten-silver and tungsten-copper contacts are products based on refractory metal tungsten, their physicochemical properties, production methods, and applications are fundamentally similar. It should be noted that the price of silver is generally higher than that of copper. Taking tungsten-copper contacts as an example, they are electrical contacts primarily composed of tungsten with copper as an auxiliary material, forming a pseudo-alloy product made of…
