Tungsten carbide powder (WC powder) is a compound composed of the refractory metal tungsten and non-metallic carbon, featuring high density, high melting point, high strength, high hardness, heat resistance, corrosion resistance, wear resistance, and good electrical and thermal conductivity. These properties make it an ideal material for hard alloy tools.

Like cerium-tungsten, lanthanum-tungsten, zirconium-tungsten, and yttrium-tungsten electrodes, the thorium-tungsten electrode is a product made by doping metal tungsten with the corresponding oxide. Though it was the earliest used and remains the best-performing tungsten electrode for welding to date, its strong radioactivity has led to its gradual replacement by rare earth tungsten electrodes. Below is an introduction to the basic information about thorium-tungsten electrodes.

Although both thorium-tungsten and cerium-tungsten electrodes are primarily made from metal tungsten and cerium-tungsten can often substitute for thorium-tungsten, differences in their dopants lead to variations in appearance, performance, production processes, and applications.

Like tungsten-copper, tungsten-molybdenum, and tungsten-nickel-iron alloys, tungsten-rhenium alloy (W-Re) is a type of high-density tungsten-based alloy that combines the excellent properties of both metal tungsten and metal rhenium. It is widely used in aerospace, aviation, maritime, military, and defense fields. Below is the basic information about this alloy:

As a type of hard alloy, steel-bonded hard alloy combines the excellent properties of hard compounds and steel, primarily used in the manufacturing of wear-resistant parts and machine components. Below is an introduction to the basic information about this alloy material.

Compared to traditional shielding materials such as iron, lead, and cement, tungsten alloy shielding components offer superior overall performance. For instance, under the same thickness and working conditions, tungsten alloy shielding materials provide better or longer-lasting shielding effectiveness and service life than traditional materials. Moreover, it is a non-toxic, environmentally friendly, and non-radioactive material, thus posing no secondary harm to the ecosystem. Below is an introduction to the basic information about these alloy shielding components.

Metal tungsten, due to its high melting point, strong electron emission capability, and low vapor pressure, has become the preferred choice for thermionic emission materials. However, its high electron work function, elevated electrode tip temperature, and tendency for grain growth lead to unstable arc beams, difficult arc initiation, and a short service life in pure tungsten electrodes, limiting their use to alternating current welding. To overcome these drawbacks, manufacturers often add rare earth oxides with low electron work functions, such as lanthanum oxide, cerium oxide, and yttrium oxide, to pure tungsten materials. This not only increases the recrystallization temperature of the product but also enhances electron emission.

As one of the primary cutting tools for high-hardness brittle materials, the quality of diamond wire depends not only on the production method, the size and distribution density of diamond particles, but also on the performance and thickness of the tungsten wire core. Generally, cutting wire produced using an electroplating process offers stronger cutting ability compared to that made with resin binders, primarily due to better diamond consolidation. The size of diamond particles should be moderate and evenly distributed; if the particles are too large, the cutting wire becomes too thick, increasing silicon wafer loss rates, whereas if they are too small, the cutting effectiveness decreases.

In daily life, as you pass by a machining workshop, you might catch a glimpse of a shiny metal ring on a robotic arm. Step into a medical device research lab, and you might find it quietly nestled within a critical piece of equipment. These rings, though seemingly ordinary, have a unique "heritage"—they are tungsten alloy rings.

In today’s era of rapid technological advancement, our lives are filled with a variety of high-tech products, from smartphones to advanced aerospace vehicles, all of which rely on a high-performance material—tungsten alloy rods—for stable operation. Though you may not often notice it in daily life, it plays a vital role in numerous critical fields.
