Our experience:

With decades of expertise in non-standard hard alloy manufacturing, Bortome Carbide has established a state-of-the-art production line in China, specializing in precision-engineered carbide prefabricated parts.

Leveraging advanced CIP (Cold Isostatic Pressing) billet forming technology and a fully integrated production system, we offer flexible order policies with no minimum quantity requirements, coupled with customized solutions tailored to client-specific blueprints. Our capabilities are further enhanced by a partner network providing precision grinding services and global express delivery, ensuring rapid fulfillment of complex, geometrically challenging tool blank materials.

 

FAQ for tungsten carbide preforms:
Q1: What is a tungsten carbide preform? What is near-net-shape?

A: Tungsten carbide preform is semi-finished carbide blank pre-machined with complex profiles (steps, tapers, coolant holes, special contours) at pressed compact stage before sintering. Near-net-shape means the sintered part is extremely close to final dimension, drastically reducing post-sinter grinding & wire EDM cost.

 

Q2: What grades of tungsten carbide preforms do you offer?

A: As a professional manufacturer of tungsten carbide preforms, we provide a full range of cemented carbide grades, including BU06, BU09, YG10X, BT15, BT20, BT25UF, YG6, YG8, YG10, YG13, YG15, YG20, YN5, YN6, YN8, YN10, YN14, YN15 and YN20, ultrafine and submicron grain carbides, as well as equivalent ISO-grade WC-Co and corrosion-resistant WC-Ni alloys. All grades can be customized according to customers’ actual working conditions for applications including cutting, stamping, mining and wear-resistant components.

 

Q3: Can you make non-cobalt tungsten carbide preforms?

A: Yes. We produce WC-Ni, WC-Ni-Cr preforms for corrosive working environment where cobalt leaching is forbidden.

 

Q4: Can you make tungsten carbide preforms with internal coolant holes?

A: Yes. We pre-drill straight /spiral coolant holes on green preforms, holes keep intact after sintering without secondary drilling, greatly save processing cost for drill & end mill manufacturers.

 

Q5: What complex shapes can your carbide preforms support?

A: Step shafts, T-shape blanks, special nozzles, gear preforms, micro drill blanks, eccentric parts, grooved preforms, custom irregular profiles according to customer’s drawings.

 

Q6: What is the standard dimensional tolerance of sintered carbide preforms?

A: Standard tolerance: ±0.1mm for general preforms. Tighter tolerance ±0.03~±0.05mm is available for precision series with extra HIP treatment. All preforms allow small finish grinding to reach final drawing tolerance.

 

Q7: What is your lead time?

A: In-stock items can be shipped within 2–3 days. New non-standard customized orders take 7–15 working days, subject to processing complexity.

 

Q8: What is your MOQ for custom carbide preforms?

A: Small trial order MOQ: 1 piece for new development.

FAQ for solid carbide rods:
Q1: What are solid carbide rods?

A: Solid carbide rods, also called tungsten carbide rods or solid carbide round blanks, are high-performance powder metallurgy blanks manufactured from tungsten carbide (WC) powder bonded with cobalt (Co) via pressing and vacuum sintering. As a standard tool and wear-part stock material, they are widely used to produce solid end mills, drills, reamers, micro cutters, ejector pins and precision mold components. Unlike steel-body carbide tools, the entire rod is made of 100% WC-Co alloy without a steel substrate.

 

Q2: What are solid carbide rods used for?

A: Cutting tool blanks: End mills, drills, taps, reamers, PCB micro drills, engraving cutters and micro precision tools.
Wear & mold components: Ejector pins, nozzles, seal pins, punches, core pins, wear bushings and precision gauges.
They are standard stock for mold manufacturing, automotive, aerospace, medical device, 3C electronics and general precision machining industries.

 

Q3: What is the difference between sintered carbide blank and ground carbide rod?

A: As-sintered carbide blank: Unprocessed after sintering, with a rough sintered skin, loose dimensional tolerance and lower unit cost. Requires full in-house grinding before use.
Ground carbide rod: Processed via double-pass centerless grinding, with controlled outer diameter tolerance, smooth surface and sintered skin removed. It is ready for direct fluting and tool manufacturing, saving internal grinding time for tool makers.

 

Q4: Are your solid carbide rods cryogenically treated?

A: Yes, all our solid carbide rods undergo a standardized deep cryogenic treatment as a mandatory factory process, with no extra charge for standard specifications.
This controlled deep-freeze procedure relieves residual sintering stress, stabilizes the cobalt binder phase and homogenizes the tungsten carbide microstructure. It effectively reduces the risk of microcracking, edge chipping and breakage during tool grinding, fluting and heavy-duty machining.
The treatment also improves wear resistance and long-term dimensional stability, extending the service life of finished carbide tools including end mills, drills, reamers and precision wear parts. Custom treatment parameters for special grades are available on request.

 

Q5: Do you support non-standard custom specifications?

A: Absolutely. As an experienced manufacturer of solid carbide rods, we offer full one-stop customization services, including special outer diameters, custom lengths, flat surfaces, and step rods. You can send us your technical drawings for an accurate quotation and tailored production planning.

 

Q6: What is your minimum order quantity (MOQ) for solid carbide rods ?

A: Orders for standard in-stock carbide rods start from 1 kg with no strict MOQ. For custom non-standard sizes and special grades, the MOQ ranges from 1 kg to 5 kg, subject to the exact specification.

 

Q7: What is your lead time?

A: In-stock items can be shipped within 2–3 days. New non-standard customized orders take 7–15 working days, subject to processing complexity.
