• Optional Surface Coatings: For certain applications, specialized coatings (e.g., nickel, titanium) are available to improve adhesion and enhance heat dissipation.

Available Grades and Applications

We offer three distinct grades of synthetic diamond micropowders, each developed for specific applications and conditions, ensuring you have the right material for your unique needs:

HG-AB071 (Type I)

Description: This versatile micropowder is specifically formulated for resin bond systems, delivering reliable performance in applications that demand both efficiency and a good surface finish without requiring extremely tight tolerances.
Key Applications:

• Gemstone Polishing: It achieves brilliant and consistent finishes on a wide array of gemstones.
• Precision Wire Sawing: It provides clean and efficient cuts in various materials, demonstrating reliable performance.
• Stone Polishing: Ideal for producing satisfactory surface finishes on different types of stone.
• Wire Drawing Die Polishing: Effectively polishes dies, enhancing their longevity and performance.

Note: This product is not available with a coating.

HG-AB072 (Type II)

Description: Engineered for resin bond systems, this grade is particularly well-suited for lapping and grinding operations on delicate and hard materials. It is a polycrystalline material, meaning it possesses a more brittle fracture characteristic than monocrystalline diamonds, which can be advantageous for continuous self-sharpening during use.
Key Applications:

• Glass Lapping and Polishing: It provides reliable and safe performance for achieving precise finishes on glass surfaces.
• Wafer Lapping and Polishing: Essential for achieving the flatness and surface quality required in semiconductor manufacturing.
• Composite Sheet Lapping and Polishing: It ensures consistent and high-quality finishes on various composite materials.
• Crystal Grinding: Highly recommended for achieving precise material removal on crystalline structures.
• PCD (Polycrystalline Diamond) Grinding: It effectively grinds PCD tools, maintaining their sharpness and performance.

Coating Options: Available with 56% or 30% nickel coating to enhance performance in demanding conditions by improving diamond retention and heat dissipation.

HG-AB073 (Type III)

Description: Specifically designed for resin bond systems, this advanced micropowder is characterized by its polycrystallinity, featuring thousands of tightly bonded crystallites within each grain. This unique structure ensures continuous exposure of new, sharp cutting edges during the abrasive process, leading to superior material removal and extended tool life.
Key Applications:

• Silicon Wafer Processing: Critical for grinding and slicing silicon wafers with exceptional precision and efficiency.
• Glass Grinding: It delivers superior performance in the grinding of various glass types.
• Carbide Grinding: Highly effective for shaping and sharpening hard carbide materials.
• Ceramic Grinding: It provides excellent results in grinding diverse ceramic components.
• Encapsulation Cutting: It ensures clean and precise cuts in encapsulation materials.

Coating Options: Available with 56% or 30% nickel coating or titanium coating for optimal performance in the most challenging applications, enhancing bonding strength and thermal stability.
