Ni Coated Diamond Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

Ni Coated Diamond Powder is a nickel-coated synthetic diamond developed primarily for resin-bond abrasive tools requiring improved grit retention, heat distribution and stable grinding performance. The metallic nickel layer provides stronger mechanical anchoring between the diamond and bond, helping reduce premature grit pull-out while maintaining consistent diamond exposure in precision grinding applications.

Features

Nickel Surface Coating: Provides a controlled metallic layer around the diamond particles for improved bond compatibility.
Improved Grit Retention: Enhances mechanical anchoring in resin-bond systems and helps reduce premature diamond pull-out.
Improved Heat Distribution: The metallic coating helps transfer grinding heat into the surrounding bond structure.
Controlled Diamond Exposure: Coating level can be matched to particle size and bond requirements to balance retention and cutting activity.
Surface Protection: Provides additional protection to the diamond surface during tool manufacturing and grinding.
Resin-Bond Compatibility: Particularly suitable for resin-bond grinding wheels and precision abrasive tools.
