Cemented carbide—an alloy made primarily of tungsten carbide (WC) and binders like cobalt (Co) or nickel (Ni)—is celebrated for its exceptional hardness, wear resistance, and heat resistance (withstanding temperatures up to 1,000°C). These properties make it an indispensable material across ... Read More

Cemented carbide products with tungsten carbide (WC) as the core raw material are widely recognized as "highly wear-resistant materials" in the industrial sector. Their wear resistance far exceeds that of ordinary steel, cast iron, and even ceramics, allowing them to be used continuously for ... Read More

In flat knife applications (such as die-cutting, trimming, and stamping), professionals have long been troubled by two issues: pure steel flat knives wear quickly, while pure tungsten carbide flat knives are costly and brittle. In reality, "steel-inserted tungsten carbide flat knives" are already a ... Read More

In the slitting process of corrugated paper processing, many professionals wonder: Why can’t a single knife be used like cutting ordinary paper, but instead a combination of "upper knife + lower knife" is necessary? The core reason lies in the special multi-layered wave structure of corrugated paper... Read More

In the corrugated paper processing chain, slitting is a critical link connecting "raw paper rolls" to "finished cardboard/cartons." It involves cutting large corrugated paper rolls into specified widths or lengths based on downstream needs (e.g., carton dimensions, packaging specifications). However... Read More

In the cemented carbide industry, many people know it is "hard and wear-resistant" but are unclear about its specific material composition. In fact, cemented carbide is not a single material but a composite made by combining "hard phases," "binder phases," and small amounts of "additive phases" in ... Read More

In the field of tungsten carbide products, "solid tungsten carbide" is often mentioned but easily confused with ordinary tungsten carbide products. Many people assume all tungsten carbide parts are "solid," but this is not the case. Ordinary tungsten carbide products may be "insert-type" (e.g., ... Read More

In the tungsten carbide industry, as global environmental regulations tighten, tungsten ore resources become scarcer, and the cost of virgin tungsten carbide raw materials rises, "recycled tungsten carbide" has gradually shifted from a "niche option" to a focus of industry attention. However, many ... Read More

In industrial scenarios like mold manufacturing, deep-hole drilling, and high-speed milling, cemented carbide rods serve as the base material for core cutting and forming tools. However, traditional solid carbide rods have a critical shortcoming: the heat generated during machining cannot be ... Read More

Stainless steel is widely used in machinery, chemical, and food industries for its excellent corrosion resistance, but it has inherent weaknesses in wear resistance, high-temperature strength, and surface hardness. Tungsten coatings—a thin layer of tungsten or tungsten alloy applied to stainless ... Read More
