Overview of High Quality 12mm-400mm Tungsten Carbide Alloy lumps/granules Alloy powder/particles
Metal powder is a common form of metal that has been processed into fine particles, ranging from a few micrometers to over 100 microns in diameter. It plays a crucial role in various industrial applications due to its unique properties and versatility.
Features of High Quality 12mm-400mm Tungsten Carbide Alloy lumps/granules Alloy powder/particles
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of High Quality 12mm-400mm Tungsten Carbide Alloy lumps/granules Alloy powder/particles
Tungsten Carbide (WC) is a high-performance material known for its exceptional strength, hardness, and wear resistance, making it a popular choice in various industries, including aerospace, automotive, and manufacturing. The 12mm-400mm Tungsten Carbide Alloy lumps, granules, and alloy powder/particles you are referring to possess unique characteristics that set them apart.
Starting with the size range, the 12mm-400mm refers to the particle diameter. This broad spectrum allows for versatility in applications where different grain sizes are required. Smaller particles (12mm) offer a higher surface area, enhancing reactivity in chemical processes or improved bonding in metal matrix composites, while larger particles (400mm) provide better mechanical stability and reduced risk of clogging in machinery.
The tungsten carbide composition consists of approximately 95% tungsten and 5% carbon. The high tungsten content imparts the material with remarkable hardness, with a Rockwell hardness of over 85HRC. This hardness makes it suitable for extreme wear environments, such as cutting tools, dies, and wear-resistant coatings.
The alloy’s microstructure, typically a combination of cementite (Fe3C) and WC particles, provides excellent wear resistance and fracture toughness. The carbide particles within the matrix act as hard particles that protect the softer iron matrix, resulting in a material that can withstand high loads and maintain its integrity under harsh conditions.
The lumps and granules are produced through advanced manufacturing processes like sintering, which involves heating and pressing tungsten carbide powders under high pressure to form a dense, cohesive structure. This process ensures minimal porosity and enhances the material’s mechanical properties. The purity of the tungsten carbide alloy is crucial, as impurities can affect performance; hence, strict quality control is maintained during production.
In terms of particle shape, these tungsten carbide particles are usually irregular, providing a more uniform distribution of mechanical properties throughout the material. This morphology contributes to better tribological performance and reduces the risk of localized wear in applications where contact is inevitable.
The lack of any specific format indicates that the product can be supplied in various forms, such as lump, granular, or fine powder, depending on the customer’s requirements. This flexibility enables customization for different processing methods and end-use applications, whether it’s for forging, machining, or as an additive in composite materials.
In summary, the 12mm-400mm Tungsten Carbide Alloy lumps, granules, and powder/particles are a high-quality engineering material characterized by their exceptional hardness, wear resistance, and size versatility. Their superior performance makes them indispensable in demanding industries, where reliability and longevity are paramount. With careful manufacturing and customizable formats, these tungsten carbide products cater to a wide range of applications, ensuring optimal performance and efficiency.
