Tungsten Carbide Stripes
Application Scenarios of Stripes
Tungsten carbide alloy strips, with characteristics such as high hardness, wear resistance, and high-temperature resistance, are widely used in industrial fields requiring abrasion resistance and high strength, including mechanical processing (e.g., cutting tools, molds), mining (drilling tools, tunneling equipment), petrochemicals (wear-resistant linings, seals), metallurgy (rolling rolls, wear-resistant components), and electronics & semiconductors (wafer cutting tools).

What parameters need to be understood?
When purchasing tungsten carbide alloy strips, the following key parameters should be focused on, as they directly affect the product’s performance, applicability, and usage scenarios.
MaterialCompositionParameters
Category | Description | Impact |
---|---|---|
Tungsten Carbide (WC) Content | Determines the hardness and wear resistance of the alloy, typically ranging from 85% to 99%. | Higher content enhances hardness but reduces toughness (suitable for high-wear scenarios like cutting tools); lower content (with more cobalt) improves toughness (ideal for impact-loading environments). |
Binder Type and Content | Common binders include cobalt (Co), usually at 1%–15%. | Higher cobalt content strengthens the alloy’s toughness and impact resistance, but reduces hardness and wear resistance (e.g., for geological drilling bits). |
Physical and Mechanical Property Parameters
Category | Description | Details |
---|---|---|
Hardness | Common indicators: Vickers hardness (HV) or Rockwell hardness (HRA). | Example: Typical range is HV 1300–2500 (HRA 85–93). Higher hardness improves wear resistance (suitable for cutting tools, wear-resistant linings). |
Density | Tungsten carbide alloy density is ~14–15.6 g/cm³. | Higher density indicates better compactness and lower internal porosity. Impact: Low density may signal insufficient sintering, affecting strength. |
Flexural Strength | Measures the material’s resistance to bending fracture, in MPa (common range: 1300–3000 MPa). | Application: High flexural strength suits alternating load scenarios (e.g., stamping dies, mining rock drills). |
Impact Toughness | Reflects the material’s resistance to impact failure, in J/cm². | Note: Tungsten carbide alloys have lower toughness than metals; choose appropriate cobalt content to balance toughness and hardness based on working conditions. |
Dimensional and Shape Specifications
Category | Description | Details |
---|---|---|
Geometric Dimensions | Diameter/cross-section & Length | Round alloy strips typically have a diameter of 1–50 mm; square/irregular strips require customized dimensions. Common length range is 10–1000 mm, determined by equipment installation space or processing needs. |
Shape Tolerance | Diameter tolerance & Straightness/verticality | Diameter tolerance: e.g., ±0.01 mm (precision grade), ±0.1 mm (standard grade). Strict control of straightness/verticality is needed for precision assembly (e.g., machine tool guides, mold components). |
Surface Roughness | Unit & Application | Unit: μm (e.g., Ra 0.8 for smooth surfaces, Ra 3.2 for general machined surfaces). Smoother surfaces have lower friction coefficients, suitable for scenarios requiring reduced wear or sealing (e.g., pump shafts, bearings). |
Quality and Process Parameters
Category | Description | Details |
---|---|---|
Sintered Density | Ideal density & detection method | Ideal density approaches the theoretical value (15.6 g/cm³). Insufficient density may cause internal pores, affecting strength. Detection: Non-destructive testing (e.g., ultrasonic) confirms internal defects. |
Microstructure | Tungsten carbide grain size | Fine-grain (<1μm) alloys have higher hardness, while coarse-grain (>5μm) alloys offer better toughness. Example: Fine-grain alloys suit precision machining, while coarse-grain alloys are ideal for mining tools. |
Surface Treatment | Coatings & passivation/polishing | Coatings: TiN, TiC coatings enhance wear and oxidation resistance (for cutting tools). Passivation/polishing: Alloy strips for medical or food equipment require surface passivation to prevent corrosion. |
Environmental Adaptability Parameters
Category | Description | Details |
---|---|---|
Operating Temperature | Tungsten carbide alloys resist high temperatures (up to >1000°C), but note that cobalt binders may soften at high temperatures. | Application: High-temperature scenarios (e.g., metallurgical furnace components) require high-tungsten, low-cobalt alloys. |
Corrosion Resistance | Tungsten carbide itself is highly resistant to acids and alkalis, but cobalt binders may corrode in strong acids/alkalis. | Confirm the service environment medium (e.g., chemical equipment needs additional anti-corrosion treatment). |
Wear Resistance | Evaluated via abrasive wear tests (e.g., dry sand rubber wheel wear test); | Lower wear amount indicates better wear resistance. |
