Tungsten carbide is a remarkable material known for its exceptional hardness and durability. It is widely used in various industries, including manufacturing, construction, and mining, due to its unique properties. However, not all tungsten carbide is created equal. There are different grades available, each with specific characteristics that make them suitable for various applications. In this blog post, we will explore the different grades of tungsten carbide and their respective uses.

Grade Identification:

Tungsten carbide grades are identified by a combination of numbers and letters that represent their specific properties. The most commonly used system is the ISO standard, which classifies grades by their particle size, binder content, and hardness. For example, a typical ISO grade may be denoted as "K20", where "K" indicates tungsten carbide and "20" represents its hardness on the Rockwell scale.

Grades and Their Applications:

1. General Purpose Grades:

General purpose tungsten carbide grades are versatile and commonly used in a wide range of applications. These grades have moderate hardness and good wear resistance, making them suitable for cutting tools, drilling bits, and wear parts. They offer a balance between toughness and hardness, making them ideal for general machining applications.

2. Heavy Cutting Grades:

Heavy cutting grades of tungsten carbide are specifically designed for demanding machining operations that involve high speeds and heavy metal removal. These grades have higher hardness and wear resistance, allowing them to withstand the extreme forces generated during heavy cutting operations. They are commonly used in aerospace, automotive, and die-casting industries.

3. Wear-Resistant Grades:

Wear-resistant tungsten carbide grades are engineered to provide excellent resistance to abrasion, erosion, and adhesive wear. These grades are often used in applications where parts and components are subjected to harsh environments, such as mining, oil and gas, and cement industries. Their superior wear resistance ensures prolonged service life and reduced downtime.

4. Fine-Grained Grades:

Fine-grained tungsten carbide grades are known for their exceptional strength and toughness. These grades have a smaller tungsten carbide particle size, leading to increased hardness and improved resistance against chipping and cracking. Fine-grained grades are commonly used in high-precision applications, such as micro-drills, micro-milling cutters, and micro-parts.

5. Submicron Grades:

Submicron tungsten carbide grades represent the latest advancement in the field, offering enhanced hardness, toughness, and wear resistance. These grades have an even smaller particle size, typically below one micrometer, resulting in outstanding performance in micro-drilling, micro-milling, and other ultra-precision machining applications.

Choosing the Right Grade:

Selecting the appropriate tungsten carbide grade is crucial for achieving optimal performance and maximizing tool life. Factors to consider include the specific application requirements, material being machined, cutting conditions, and desired surface finish. Consulting with tungsten carbide experts or manufacturers can help determine the most suitable grade for a particular application.

In conclusion, the different grades of tungsten carbide offer a wide range of options to meet specific application requirements. Whether it be general machining, heavy cutting, wear resistance, fine-grained precision, or ultra-precision micro-machining, there is a tungsten carbide grade designed for the task at hand. Understanding the distinct properties of each grade empowers manufacturers and engineers to make informed decisions, ensuring the best results and long-term success in their respective industries.
