Overview of Supply high purity 99.95% wc raw materials for cemented carbide
Supply high purity 99.95% wc raw materials for cemented carbide comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of Supply high purity 99.95% wc raw materials for cemented carbide
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Supply high purity 99.95% wc raw materials for cemented carbide
When it comes to high purity 99.95% WC (Tungsten Carbide) raw materials for cemented carbide, several parameters are crucial for ensuring optimal performance and quality. Here are some key parameters to consider:
1. **Grade of Tungsten Carbide**: WC particles should be of a specific grade, such as WC80, WC90, WC92, or WC95, indicating the tungsten content in the powder. A higher percentage indicates better wear resistance.
2. **Particle Size Distribution (PSD)**: The powder should have a narrow PSD to ensure consistent bonding and minimize voids in the final product. Common particle size ranges include 32-63 micron, 45-75 micron, or 75-150 micron, depending on the desired application.
3. **Shape and Structure**: WC particles should be spherical or near-spherical for better flowability and uniform distribution during the compaction process. This can also affect the mechanical properties of the final cemented carbide.
4. **Purity**: As mentioned, the purity should be at least 99.95% to minimize impurities that could affect strength, hardness, and wear resistance. Impurities like cobalt, iron, or titanium can be present in trace amounts.
5. **Hardness and Microhardness**: High purity WC should exhibit excellent hardness and microhardness values, which are essential for its wear resistance and durability.
6. **Density**: Dense WC powders result in better density and mechanical properties in the final cemented carbide. The density should be close to (19.25 g/cm³) to ensure efficient use of the material.
7. **Luster and Color**: Freshly ground WC particles should have a bright metallic luster, indicating good purity and minimal contamination.
8. **Homogeneity**: The powder should be chemically homogeneous, with a consistent composition throughout the batch to ensure consistent performance.
9. **Moisture Content**: Low moisture content is vital to prevent caking and maintain proper flowability during processing. Ideally, the moisture content should be below 0.5% to ensure a stable mixture.
10. **Supplier Quality Control**: Ensure that the supplier has robust quality control processes in place, including regular testing for purity, particle size, and other critical parameters.
These parameters should be provided by the manufacturer when sourcing high purity 99.95% WC raw materials for cemented carbide applications.
