YG8 Tungsten Carbide Flat Bar Blank 0.31" x 1" x 8" (8 x 25 x 200 mm) 1Pcs Industrial Grade Unfinished Cemented Carbide Bar for Tool Blanks & Wear Parts (K20–K30 Equivalent)

Professional Tungsten Carbide Flat Bar for Industrial Applications This YG8 tungsten carbide flat bar (As-Sintered Blank) is manufactured from cemented carbide material, providing excellent wear resistance combined with reliable impact strength. It is designed for industrial users who require consistent performance in cutting, wear, and tooling applications. Compared with tool steel or HSS materials, tungsten carbide offers significantly longer service life in abrasive and high-wear environments. Note: Supplied in as-sintered, unfinished condition. This product is a carbide blank for custom machining and tool fabrication, not a ready-to-use cutting insert. Technical Information Component Content: Tungsten Carbide (WC) ≈ 92% Cobalt (Co) ≈ 8% Grade: YG8 Equivalent (ISO K20–K30) Surface Condition: As-sintered (unfinished) Density: 14.5–14.7 g/cm³ (≈2× density of steel) Hardness: HRA 89–90 (≈1550–1650 HV), extreme wear resistance (≈3-4 times higher than HSS) Transverse Rupture Strength (TRS): 1600–1800 MPa, moderate toughness (superior to grades with <8% Co) High-Temp Oxidation Resistance: Stable <500°C; rapid oxidation >500°C (Co oxidizes first) Typical Applications Rough machining tool blanks Woodworking and planer knife blanks Plastic and rubber cutting tools Wear strips and guide bars Scraper and slitter blades Industrial maintenance and repair parts Machining Recommendations Recommended: wire EDM, diamond grinding Suitable for silver brazing with proper preheating Avoid thermal shock during heating or cooling

• Industrial Grade Tungsten Carbide: Made from cemented tungsten carbide (YG8 equivalent), offering an excellent balance of hardness and toughness. Designed for long service life under wear and moderate impact conditions.
• Superior Wear Life vs Tool Steel & HSS: Compared with tool steel or high-speed steel, YG8 tungsten carbide offers significantly higher wear resistance and longer service life, while maintaining better impact reliability than ceramic materials.
• Ideal for Tool Blanks & Wear Parts: Commonly used for rough machining tool blanks, woodworking knife blanks, plastic and rubber cutting tools, wear strips, scraper blades, and industrial repair or fabrication projects.
• Multiple Sizes & Customization Supported: Available in various thicknesses, widths, and lengths. Custom sizes and cutting options are supported for tooling, maintenance, and non-standard industrial needs.
• Machining & Processing Notes: Suitable for wire EDM machining and silver brazing. Not intended for conventional turning or milling. Proper preheating and slow cooling are recommended during brazing.
