Synthetic Diamond Compound - Medium Concentration
Comparable to Buehler MetaDi monocrystalline diamond paste, Struers DP-Paste, and Allied High Tech monocrystalline diamond compound for the same intermediate and fine polishing steps — at 20 to 40 percent lower cost.
Overview
Synthetic Diamond Compound — Medium Concentration
What This Product Is
Synthetic diamond compound is a monocrystalline diamond paste — each particle is a single synthetic diamond crystal with sharp, well-defined edges that cut aggressively and predictably. This is the general-purpose diamond paste for metallographic polishing, supplied here in medium concentration, which balances material-removal rate against surface finish for everyday preparation.
Intended Use in Metallography
Used for intermediate and fine polishing, medium-concentration synthetic compound is the default choice when:
- A single, versatile diamond paste is wanted for routine samples
- Controlled, predictable cutting is preferred
- Balancing removal rate and finish rather than maximizing either
- Following an established monocrystalline-diamond procedure
Typical Applications
Commonly used when polishing:
- General metals and alloys
- Steels and ferrous materials
- Routine production, QC, and teaching-lab samples
- Samples of relatively uniform hardness
Beyond metallography, this compound is also used in:
- Petrography thin-section polishing
- Ceramics and precision components
- Glass and optics
- Tool and die finishing
When This Product Is NOT Ideal
Medium-concentration synthetic compound may not be the best choice when:
- Large surface areas or hard materials need maximum removal — heavy concentration is better
- Hard, mixed-phase materials need polycrystalline diamond to control relief
- Coarse removal is needed, which is a grinding step
Where This Fits in the Preparation Process
Synthetic diamond compound is typically used:
- After grinding
- Before an oxide final polish, when required
Applied to a polishing cloth with a compatible water- or oil-based lubricant.
Best-Practice Notes
- Medium concentration suits most routine work; step up to heavy for faster removal or larger areas
- One micron size per cloth; recharge as cutting slows
- Add lubricant to carry the diamond and manage heat
- Clean between steps to prevent carryover

Frequently Asked Questions
What does "medium concentration" mean?
Concentration refers to the amount of diamond per unit of paste. Medium concentration balances material-removal rate and finish and is the general-purpose choice; heavy concentration carries more diamond for faster removal.
Monocrystalline (synthetic) or polycrystalline compound?
Monocrystalline (this product) is single-crystal diamond that cuts sharply and predictably — a strong general-purpose choice. Polycrystalline is multi-crystal with a self-sharpening action, often preferred for hard or mixed-phase materials.
When should I move up to heavy concentration?
When you need faster material removal, are polishing larger surface areas, or are working harder materials where medium concentration is slower than you want.
Water-soluble or oil-soluble?
Water-soluble for most general work; oil-soluble for moisture-sensitive materials or an oil-based process.
Can this diamond compound be used outside metallography?
Yes. Monocrystalline diamond compound is a general-purpose precision polish used across petrography, ceramics and precision components, glass and optics, and tool and die work — not only metallography. Medium concentration is the versatile choice for most of these; step up to heavy for larger areas or harder stock.
