Nickel-Plated Diamond N56 (56% Nickel Coating Content)
SinoDiam N56 – Spiny Surface for Resin and Ceramic Bond Tools
Top Introduction
SinoDiam Nickel-Plated Diamond N56 is a high-adhesion, surface-functionalized diamond featuring 56% nickel coating content and a unique spiny surface.
The thick nickel layer and micro-hooked texture dramatically improve matrix grip, making N56 perfect for resin bond and ceramic bond tools that require strong particle retention, including precision polishing pads and ceramic grinding wheels.
Description
SinoDiam N56 Nickel-Plated Diamond stands out with two distinctive features: a high 56% nickel coating content for maximum adhesion and a spiny surface that locks diamond particles into resin and ceramic matrices.
The spiny “micro-hook” texture reduces diamond fall-off by 50% compared with standard smooth-coated diamonds (and 10% more than N30), solving particle retention issues in resin-bonded polishing tools and ceramic grinding wheels.
Available in 500/600 mesh and coarser grades, N56 suits both fine resin tools for smooth finishing and large ceramic wheels for heavy-duty processing. The coating maintains stability at temperatures up to 700°C, ensuring long tool life while delivering consistent cutting and polishing performance.
Core Advantages
- 💪 High 56% Nickel Coating Content: Thick layer for superior adhesion to diamond particles, ideal for long-term use.

FAQ
Q1: What does “N56” represent for this product?
A: N56 refers to 56% nickel coating content—a thicker layer than N30, combined with a spiny surface for maximum adhesion in resin/ceramic bond matrices.
Q2: Why is N56 not recommended for metal bond tools?
A: Its 56% nickel content and spiny surface are optimized for resin/ceramic matrices. For metal bond tools, use N30 or Titanium-Coated Diamond, which have better high-temperature resistance.
Q3: What mesh size works best for resin polishing pads?
A: Fine grades (500/600–800/1000 mesh) are ideal. The 56% nickel coating and spiny surface ensure strong adhesion to resin while achieving smooth finishes (Ra ≤0.8μm).
