Our metal-coated diamond products are engineered to elevate industrial tool performance, delivering longer tool life, higher wear resistance, and superior bonding with tool matrices. By applying precision metal coatings—such as titanium, nickel alloys, and titanium carbide—to high-purity diamond particles, these advanced abrasives solve common challenges in diamond saw blades, grinding wheels, PCD/PCBN tools, and drill bits, including rapid wear, poor adhesion, and low compatibility with high-stress applications.
Perfect for industries like stone processing, construction, aerospace, automotive, mining, and electronics manufacturing, our metal-coated diamond abrasives are optimized for metal-bond, ceramic-bond, hybrid-bond, and resin-bond tools, delivering consistent high-speed cutting, smooth finishes, and reduced vibration across diverse materials.
Core Benefits of Metal-Coated Diamond
- Stronger Tool Bonding: Titanium, nickel, and carbide coatings create robust mechanical and chemical adhesion to metal, ceramic, or resin matrices, reducing particle loss during high-pressure cutting and grinding.
- Enhanced Wear Resistance: Protective metal layers improve heat, friction, and chemical resistance, extending tool life in dry cutting, high-temperature machining, and abrasive material processing.
- Versatile Compatibility: Compatible with all major tool bonding systems and effective on granite, marble, concrete, carbide, aerospace alloys, and other hard materials.
- Consistent Cutting Performance: Controlled coating thickness (5–20μm) ensures uniform diamond particle behavior, maintaining tool efficiency and smooth workpiece finishes.

(FAQs) about metallic-coated diamond products in industrial tooling:
1. What is a metal-coated diamond?
Answer: SinoDiam’s metal-coated diamonds—including Ti Coated Diamond, N30, N56, and TiC—are synthetic diamond particles coated with metals like titanium, nickel, or titanium carbide. These coatings enhance adhesion, wear resistance, and thermal stability, making them ideal for metal-bond, ceramic-bond, resin-bond, and hybrid-bond tools in industrial cutting, grinding, and drilling.
2. Why use metal-coated diamonds instead of uncoated diamonds?
Answer: SinoDiam’s metal-coated diamonds offer:
- Stronger bonding to tool matrices, reducing particle loss.
- Higher wear resistance for longer tool life.
- Better thermal stability for high-speed and dry cutting.
- Versatility across granite, marble, concrete, carbide, and aerospace alloys.
Products like Ti Coated Diamond, N30, N56, TiC, and Surface-Etched Diamond are engineered for precision and durability in industrial applications.
3. What types of metal coatings are used on diamond abrasives?
Answer: SinoDiam uses specialized coatings for different applications:
- Titanium (Ti Coated Diamond): Strong mechanical bonding with metal matrices.
- Nickel-based alloys (N30, N56): High ductility and corrosion resistance for ceramic and hybrid-bond tools.
- Titanium Carbide (TiC): Ultra-hard coating for mining, quarrying, and heavy-duty stone cutting.
4. How does coating thickness affect diamond performance?
Answer: SinoDiam controls coating thickness between 5–20μm for optimized performance:
- Thin coatings (5–10μm, e.g., N30): Maintain sharpness for fine grinding and polishing.
- Thicker coatings (10–20μm, e.g., TiC, N56): Provide maximum wear and heat resistance for heavy-duty cutting.
Precision coating ensures stable cutting, smooth finishes, and long-lasting tool life.
5. Can metal-coated diamonds be used in high-temperature applications?
Answer: Yes. SinoDiam’s N56 and TiC-coated diamonds are designed for extreme conditions:
- N56 Coated Diamond: Stable up to 900°C, suitable for dry cutting and aerospace alloy grinding.
- Titanium Carbide (TiC): Provides enhanced thermal stability for heavy-duty mining and stone cutting tools.
6. Are metal-coated diamonds compatible with all bonding systems?
Answer: SinoDiam metal-coated diamonds work with metal, ceramic, hybrid, and resin bonds.
- Ti, N30, N56, TiC, Surface-Etched Diamonds can be used on granite, marble, concrete, carbide, and aerospace alloys.
This versatility ensures consistent performance across diverse industrial applications.
7. Can metal-coated diamonds be resharpened or recoated?
Answer: Typically, SinoDiam metal-coated diamonds cannot be resharpened or recoated. Coatings such as Ti, N30, N56, and TiC alter the diamond’s surface chemistry, and re-treatment may reduce performance and consistency.
