Grain size selection depends on the primary wear mechanism: abrasive wear versus mechanical impact. Submicron and ultra-fine grain grades (0.2–0.8 µm), such as our ZF-Nano02 series, maximize hardness (up to 93.5 HRA) and compressive strength, making them ideal for cutting tools, PCB micro-drills, and non-ferrous milling. Conversely, coarse-grain structures (2.0–3.5 µm) combined with higher cobalt content (YG15 to YG20) provide exceptional fracture toughness (K1c > 12 MPa·m^1/2), absorbing shock loads in stamping, cold heading punches, and concrete scarifying blades.

Standard vacuum sintering leaves microscopic internal voids (A04/B04 class porosities). When these blocks undergo Electrical Discharge Machining (EDM) for stamping inserts, the high-voltage arc vaporizes cobalt unevenly around these cavities, causing micro-cracking and premature spalling. In contrast, our Sinter-HIP process applies up to 60 bar of isostatic argon pressure during the liquid phase, reducing internal porosity to near-zero (A02/B00 rating) and increasing Transverse Rupture Strength (TRS) by 15–20%.

Yes. Tailored metallurgical solutions are our primary business model. Buyers can submit 2D PDF or 3D STEP drawings along with operating parameters (impact velocity, working temperature, thermal cycling, and work material chemistry). Our engineering team will calculate optimal binder content, grain size, and anti-corrosive additions (such as Cr3C2 or TaC), providing a full technical review and formal proposal within 8 hours.

Standard cemented carbide uses a cobalt binder, which is ferromagnetic and prone to magnetizing chips or interfering with sensitive electromagnetic sensors. By substituting a high-purity nickel matrix, we produce hardmetal components with magnetic permeability (µ) approaching 1.001–1.003. This enables their use in measurement-while-drilling (MWD/LWD) subsea tools, magnetic core pressing dies, and high-frequency transducer components, while also offering enhanced corrosion resistance in aggressive chloride and acidic environments.

Our CNC cylindrical centerless and profile diamond grinding shops routinely achieve h6 external diameter tolerances on solid carbide rods (e.g., +0/-0.008 mm for Ø8 mm rods) with total circular runout under 0.002 mm. For carbide plates and thick die blocks, our double-surface lap grinding delivers parallelism and flatness down to 0.005 mm across a 200 mm span, with surface finishes reaching Ra 0.05–0.1 µm (mirror-polished) upon request.

Exporting to over 20 nations—including the USA, Canada, Mexico, Germany, and Australia—our logistics team manages full international documentation, including Certificates of Analysis (COA), ISO9001 quality certificates, HS classification (8209.00 / 8207.70), and country-of-origin documentation. Orders are packaged in sealed, moisture-proof, shock-absorbing vacuum containers to avoid moisture damage during ocean or air transit.
