카바이드 로드 세부 정보

카바이드 로드 are a powerhouse in the world of machining and industrial applications. They offer unmatched durability, hardness, and wear resistance, which makes them a go-to choice in industries ranging from metal cutting to drilling and beyond. But what exactly are carbide rods, and why are they so highly valued? Let’s dive deep into the world of carbide rods and find out everything there is to know!

카바이드 로드란 무엇인가요?

Carbide rods are cylindrical, durable rods made primarily of tungsten carbide, a compound known for its extreme hardness and wear resistance. They are engineered to withstand high-impact conditions, making them a favorite for tools that require longevity and strength, such as drills, cutters, and grinding equipment. But how exactly are these rods made, and what gives them such incredible properties?

Raw Material and Composition Analysis of Carbide Rods

Carbide rods are typically made from tungsten carbide powder mixed with cobalt as a binder. The resulting compound is pressed and sintered into a rod form that is capable of handling high-pressure applications without breaking down.

• 텅스텐 카바이드(WC): The primary component, tungsten carbide, makes up about 85-95% of the composition, offering hardness.
• 코발트 (Co): Cobalt binds the tungsten carbide particles together, enhancing durability and providing slight flexibility.
