What is Tungsten Carbide? KOIHO BETTER CARBIDE’s Expertise

Understanding Tungsten Carbide

Tungsten carbide is a composite material formed by combining tungsten, a robust metal, with carbon, creating an exceptionally tough compound. Produced through a high-temperature sintering process, it consists of fine tungsten carbide particles bonded with a metallic binder, typically cobalt, to enhance strength. This results in a material that’s three times harder than steel, with a Mohs hardness of 8.5-9.5, and a melting point around 2,870°C. Its ability to withstand extreme wear and impact makes it perfect for demanding applications.

At KOIHO BETTER CARBIDE, we refine this material into micrograin tungsten carbide for our asphalt milling picks, ensuring maximum performance in grinding tough pavement surfaces. Our tools deliver the precision needed to produce high-quality asphalt millings, ideal for sustainable road projects.

Key Properties of Tungsten Carbide

Tungsten carbide’s standout traits make it indispensable for road milling:

• Extreme Hardness: Nearly as hard as diamond, it resists abrasion from aggregates in asphalt or concrete, maintaining sharpness for consistent cuts.

• High Wear Resistance: Its durability ensures long-lasting performance, reducing tool replacements and project costs.

• Thermal Stability: With a high melting point, it thrives in the heat generated by high-speed milling, preventing deformation.

• Impact Resistance: The cobalt binder enhances toughness, allowing tools to handle shocks from hidden pavement reinforcements.

KOIHO BETTER CARBIDE’s pavement milling teeth capitalize on these properties, featuring tungsten carbide tips brazed to sturdy steel bodies. This design ensures reliable milling on cold planers like Wirtgen’s W 150 CF or Caterpillar’s PM622, producing uniform millings for durable surfaces.

Applications in Road Construction

Tungsten carbide is the backbone of tools used to mill asphalt and concrete in road construction. Milling machines, equipped with rotating drums studded with carbide-tipped teeth, grind old pavement into reusable asphalt millings, or reclaimed asphalt pavement (RAP). These millings, costing 30-50% less than new asphalt, are perfect for driveways, roads, and parking lots, offering savings and sustainability by reducing waste.

KOIHO BETTER CARBIDE’s road planing bits excel in this process. Designed for versatility, they handle tasks from shallow surface corrections to deep pavement removal, producing finely graded millings that compact effortlessly. Compatible with planers like Dynapac’s PL2100 or Roadtec’s RX-700, KOIHO’s tools enhance efficiency, ensuring high-quality RAP for cost-effective projects.
