Can Zhongfu manufacture tungsten carbide parts from my drawing?

Yes. Custom carbide parts are our core business. Send a 2D/3D drawing with tolerances, surface finish and working conditions; our engineers recommend a grade and can optimize the powder formulation to match your wear, impact or corrosion requirements.

Which cemented carbide grades do you supply?

We supply standard WC-Co grades from YG6 to YG20, nano and ultrafine grain rod grades for end mills and drills, and nickel-bonded non-magnetic grades. Low-cobalt grades favor hardness and wear resistance; higher-cobalt grades favor toughness and impact resistance.

What makes non-magnetic carbide different from standard carbide?

Standard tungsten carbide uses a cobalt binder, which is ferromagnetic. Non-magnetic carbide replaces cobalt with a nickel-based binder, so parts can be used near magnetic sensors, in MWD/LWD downhole tools, magnetic molding dies and corrosive media.

How fast will I receive a technical reply?

Our engineering team replies to every inquiry within 8 hours, including grade suggestions and manufacturability comments on your drawing.

Which markets do you export tungsten carbide products to?

Our carbide products are exported to more than 20 countries, including the USA, Canada, Mexico, Australia and Germany.

Macro-Industry Engineering Solutions

Bridging theoretical metallurgy and real-world high-impact industrial operations with turnkey, custom-machined tungsten carbide components.

⛏

Deep Coring & Geothermal Mining

Down-the-hole (DTH) drilling tools face crushing mechanical loads and thermal shocks. Our tungsten inserts utilize optimized coarse-grain cobalt topologies that balance fracture toughness against dynamic impact, reducing premature button breakage and maximizing continuous run times in igneous rock.

⚙

High-Speed CNC Machining & Metalworking

For aerospace and automotive manufacturers machining hardened alloy steels and cast irons, our sub-micron carbide rods and inserts deliver edge retainment up to 1,000°C. Available with advanced PVD/CVD coatings (AlTiN, TiSiN) to eliminate flank wear and built-up edge phenomena.

🔮

Corrosion & Magnetic Sensitive Systems

Standard cobalt binders fail chemically in sour-gas wells and distort electromagnetic instrumentation in Measurement-While-Drilling (MWD) logging. Our specialized nickel-chromium bonded non-magnetic grades deliver full chemical resistance and near-zero magnetic permeability (μ ≤ 1.005).

❓ Engineering Q&A

Frequently Asked Technical & Procurement Questions

Detailed insights to resolve engineering queries, specification validations, and global supply chain logistics.

How does Zhongfu Carbide ensure consistent density and zero micro-porosity across large production batches?

We operate exclusively with 100% virgin tungsten carbide powder and avoid recycled scrap powders that introduce uncontrolled tramp elements. Our thermal processing utilizes automated Sinter-HIP furnaces that combine low-pressure vacuum dewaxing followed immediately by 10 MPa argon gas compaction at 1,450°C. This process collapses internal voids and gas pores to an ASTM porosity rating of A02/B00 or superior, ensuring consistent toughness and predictable tool life across multi-ton production volumes.

What are the mechanical tradeoffs between cobalt and nickel binders in abrasive vs. corrosive applications?

Cobalt provides superior wettability during liquid-phase sintering, yielding higher transverse rupture strength (TRS) and resistance to impact shocks, making it ideal for rock drilling, stamping, and cutting tool inserts. Nickel binders, however, are non-ferromagnetic and resist corrosive pitting in acid, alkaline, and saline environments. For downhole MWD tools, subsea valve trims, and sensor casings where magnetic permeability must remain below 1.005 μ, our nickel-bonded grades provide stable performance without field failures.

Can custom carbide bits and blanks be manufactured directly from 2D/3D customer engineering drawings?

Yes. Over 65% of our monthly output consists of customized wear parts and OEM blanks. Customers provide 2D CAD files (DWG/DXF/PDF) or 3D models (STEP/IGES) specifying dimensional tolerances, required hardness, and operating conditions. Our internal metallurgical design team evaluates shrinkage ratios during sintering (typically 18–22%), custom-engineers precision pressing dies, and formulates tailor-made cobalt or grain size recipes to match your mechanical needs.

What dimensional grinding tolerances can be held on finished carbide rods and wear parts?

Our CNC grinding center features precision centerless grinders, surface grinders, and multi-axis optical profile grinding machinery. For round rods and cylindrical shafts, we routinely deliver an h6 diameter tolerance (±0.003 mm for small diameters) with circular runout under 0.002 mm. For mirror-finished wear plates, seal rings, and dies, diamond-lapping delivers Ra 0.05 to Ra 0.02 µm surface roughness.

What are typical production lead times, and how are international shipments protected against oxidation?

Standard catalog items and pre-sintered rods are stocked for immediate dispatch within 3–5 working days. Custom-to-drawing press-and-sinter orders typically require 15 to 25 business days, including die fabrication and metallographic inspection. Export components undergo ultrasonic cleaning, vacuum sealing with vapor corrosion inhibitor (VCI) films, and packaging inside foam-cushioned wooden crates for air or ocean transit to over 20 countries.
