In the realm of cutting tools and precision machining, cemented carbide strips stand out as essential components offering exceptional wear resistance, toughness, and cutting performance. These strips, often used in tool holders, cutting blades, and inserts, form the backbone of many industrial applications requiring precision and durability.
Shanghai Diatooling, a highly specialized and experienced manufacturer and supplier of cemented carbide tools, has been delivering top-quality products that empower industries ranging from metalworking to manufacturing. This article explores the material properties of cemented carbide strips and how those properties translate into practical, high-performance applications.
What Are Cemented Carbide Strips?
Cemented carbide strips are composite materials made primarily from tungsten carbide (WC) particles bonded together with a metal matrix, typically cobalt (Co). This combination results in a hard, wear-resistant, and tough material ideal for demanding cutting and machining operations.
Key Material Properties
A. Hardness
Cemented carbide is significantly harder than conventional tool steels, enabling it to cut and shape even the toughest materials with minimal wear. This hardness ensures longer tool life and consistent machining quality.
B. Toughness
While extremely hard, cemented carbide also exhibits good toughness due to the cobalt binder, which provides some ductility to resist chipping and cracking during impact or heavy-duty cutting.
C. Wear Resistance
The fine tungsten carbide grains and strong metal bonding provide excellent resistance to abrasion and erosion, critical in high-speed machining and continuous operations.
D. Thermal Stability
Cemented carbide maintains its hardness and structural integrity even at elevated temperatures, allowing it to perform well in high-speed cutting where friction generates substantial heat.
Manufacturing Process of Cemented Carbide Strips
Powder Preparation – High-purity tungsten carbide and cobalt powders are mixed uniformly.
Pressing – The powder blend is pressed into strip shapes under high pressure.
Sintering – Heated at high temperatures in a controlled environment to bond particles and densify the material.
Grinding & Finishing – Achieving precise dimensions and smooth surface finishes to meet application needs.
Shanghai Diatooling applies rigorous quality controls at every stage to guarantee uniformity and performance.
Industrial Applications of Cemented Carbide Strips
A. Metal Cutting Tools
Used as cutting edges in turning, milling, drilling, and planing tools, cemented carbide strips enable machining of steel, cast iron, aluminum, and even hard alloys with superior precision.
B. Woodworking and Plastics
Their sharpness and durability also make them ideal for cutting wood, composite materials, and plastics, offering clean cuts and reduced tool replacement frequency.
C. Mining and Construction
In heavy industries, carbide strips are integrated into drilling bits, cutting drums, and other wear parts that must endure abrasive and high-impact conditions.
D. Industrial Machinery Components
They are used in forming rolls, punches, and dies, where resistance to wear and deformation is essential for maintaining product quality and process efficiency.
