I would like to Introduce New Item, Tungsten Cobalt Alloys available.Offer Summary: 1) Chemical Component: Tungsten (W) 67.1% + Cobalt (Co) 26.17% Alloys 2) Country of Origin: China 3) Price: FOB (kindly request buyer target price per kg) As you know well this Tungsten Cobalt Alloys is very Important Raw Material. Tungsten-Cobalt Alloys, often referred to as Cemented Carbides or Hard Metals, are materials that combine tungsten Carbide (WC) with Cobalt (Co) as a binder. These alloys are renowned for their exceptional hardness, wear resistance, and strength, making them indispensable in industrial and machining applications. A. Key Features:1) Hardness:Tungsten carbide provides extreme hardness, enabling these alloys to cut, grind, or drill even the hardest materials.2) Toughness: The Cobalt binder gives the alloy ductility and toughness, preventing brittleness and allowing it to withstand impacts. 3) Wear Resistance: These alloys resist abrasion, making them suitable for prolonged use in high-stress environments.4) Thermal Stability: They can maintain their properties at high temperatures, making them ideal for cutting tools and machinery. B. Common Applications:1) Cutting Tools: Used in milling, drilling, and turning tools for machining metals and alloys.2) Mining and Constructions: Drill bits, cutting edges, and excavation tools.3) Aerospace: Precision machining of hard-to-work materials like titanium and Inconel.4) Wear-Resistant Parts: Dies, punches, and wear inserts in various manufacturing industries.5) Medical Devices: Surgical tools that require precise cutting and wear resistance. C. Composition: - Tungsten Carbide (WC): Provides hardness and wear resistance. - Cobalt (Co) Serves and a binder, giving toughness and enhancing the alloy's performance under mechanical stress. - Optional Additives: Elements like titanium carbide (TIC) or Tantalum Carbide (TaC) are sometimes added to tailor properties for specific applications. D. Manufacturing Process: 1) Powder Metallurgy: - Tungsten carbide powder is mixed with cobalt powder. - The mixture is pressed into desired shapes under high pressure. - The Material is sintered as high temperatures to bond the tungsten carbide particles with cobalt. 2) Finishing: - The Final product is often ground or polished to active precision tolerances and smooth finishes. E. Advantages and Disadvantages: 1) Advantages: - High hardness and strength - Excellent wear and corrosion resistance. - Long Lifespan under extreme conditions. 2) Disadvantages: - Expensive due to Tungsten and Cobalt costs. - Brittle compared to softer materials.

This tungsten carbide grit also called tungsten grits, carbide grits, it is used to welding or solder onto a steel body, to increase the wear resistance properties. For example, if a steel cutter can cut 24 hours without grits, it will cut 240 hours after with the tungsten carbide grits.
Tungsten carbide gripper jaws tips are tools used to clamp and hang the casing string during the drilling process. They are used to clamp or place between the casing of the drill pipe. They are used to tighten and hang the casing string and oil string in the well to prevent them from falling into the well. Note: Other specification can be made upon customer's requirements.

Tungsten carbide cobalt sintered and crushed powder is high hardness coating powder.The sintered and crushed morphology generally produces a higher coating density compared to agglomerated and sintered powders.It offers dense, excellent bonding and provides resistant to abrasion erosion and sliding wear . The coating also has high wear resistance but with low coefficient of friction.
This tungsten carbide grit also called tungsten grits, carbide grits, it is used to welding or solder onto a steel body, to increase the wear resistance properties. For example, if a steel cutter can cut 24 hours without grits, it will cut 240 hours after with the tungsten carbide grits.
