Special line for manufacturing polycrystalline cutting inserts. Spherical grain, high strength, ultra-high purity. Fractions finer than 2 μm split into 16 levels.
Pricing is on request, delivery basis FOB China, exclusive of VAT. Micron powder cost depends on grade, fraction and quantity — please confirm by email.
Dry PCD diamond micron powder: fine free-flowing fraction with a sample vial. Illustrative image; specific batch appearance per actual delivery.
Supplied with full documentation package: standard, particle size COA, safety data sheet, and specifications. EAC declaration is the importer responsibility — we provide full technical support.
Products are characterized per ISO 13320:2020 (laser diffraction, D50/D90) and conform to GOST 9206-80 and GB/T 35477-2017. Actual fraction values for each batch are confirmed by a particle-size report (COA).
EAC compliance and declaration are the responsibility of the importer. DIAMTECH provides full technical documentation support: COA (particle size distribution, impurity analysis), MSDS, and product specifications to facilitate your EAC process.
Every batch ships with the partner factory report, re-verified by DIAMTECH. Sample on the Certificates page.
Document copies are provided before shipment.
High flowability and packing density — stable sintering result, fewer defects.
No oversized particles — clean surface, predictable wear resistance.
Proven purification system — minimal impurity impact on compact strength.
Stable at high sintering temperatures, strength retention.
Three primary grades for PCD/PDC sintering available. Other grades — dispatched from the factory in 3–5 days.
Fine PCD sintering, precision polishing
Primary PCD/PDC compact sintering
Coarse PCD sintering, diamond drill bits
Other grades and parameters — dispatched in 3–5 days
D50 deviation ≤±3.8%. Fe+Ni+Co impurities <65 ppm. Basic QC of every batch; official protocol from a CN state laboratory — on request.
PDC inserts for drill bits — impact load resistance.
Turning inserts, milling cutters for aluminum, composites, non-ferrous metals.
Wire dies — wear resistance and stable geometry.
Rock-breaking tools for tunneling and drilling.
Describe your sintering process — we will suggest a fraction and grain shape. You can attach a recipe in VK/MAX.
DIAMTECH is a diamond trading and sourcing company, not a factory. We work directly with the Henan cluster, selecting and comparing products across plants and matching the best partner plant for each batch.
Sintering powder for PCD/PDC. D50 tolerance ≤ ±3.8%; Fe+Ni+Co impurities < 65 ppm; magnetic inclusions < 0.1%; thermal stability 850 °C. Used to make synthetic diamond tools.
Yes — parameters are matched to your cutting insert: D50, size distribution and grain shape are agreed against your specification. Describe the part and we will match a batch.
Standard micron powder from 1 kg, suspensions from 5 L. The minimum for a custom fraction is 10 kg. Send us your requirement by email and we will confirm the exact MOQ for your case.
Prices are not published on this site. Cost depends on grade, particle fraction, quantity and delivery terms, and is confirmed by inquiry. Describe your requirement by email and we will send a quotation.
A COA is issued per batch on request. Test protocols from the Henan Provincial Quality Supervision & Inspection Center for Synthetic Diamond Micron Powder (Zhecheng) — China's only specialized state laboratory for micron powder — or from the National Center are available on request.
Samples are available, but the sample fee and freight are paid by the buyer (collect); both are credited to the first order. DIAMTECH does not offer free samples.
TT: 30% deposit, balance before shipment. An invoice is provided.
