This guide supports Extramet’s U.S. tungsten carbide manufacturer by answering the practical engineering and purchasing questions that usually come before an RFQ.
Quick Answer
- A complete RFQ shortens review time and reduces assumptions.
- Grade, geometry, tolerance, finish, quantity, and inspection needs should be stated together.
- If grade is unknown, describe the application and current failure mode.
| RFQ item | Why it matters | Example detail |
|---|---|---|
| Drawing | Defines geometry and tolerances | PDF plus native CAD if available |
| Grade | Controls wear, toughness, and density | Known grade or application target |
| Finish | Affects grinding and inspection | Ground, polish, as-sintered, or EDM |
| Documentation | Supports quality requirements | Certs, inspection reports, traceability |
What a manufacturer needs first
A carbide manufacturer can respond faster when the RFQ includes the drawing, grade, tolerance, quantity, and intended use. If a print is incomplete, note which dimensions are critical and which can be adjusted for manufacturability.
If the grade is not known
Do not guess based only on hardness. Describe the contact material, load, speed, lubricant, temperature, current failure mode, and expected service life. That context helps narrow cobalt binder, nickel binder, grain size, and toughness requirements.
Why single-source capability helps
When material supply, grinding, inspection, and technical review live under one roof, there are fewer handoffs. That is especially useful for carbide blanks, pins, punches, rods, and precision-ground components.
What to Include in an RFQ
- drawing or sketch
- grade or application conditions
- finished dimensions and tolerances
- quantity, finish, and inspection requirements

Frequently Asked Questions
Can I request a quote without knowing the carbide grade?
Yes. Share the application and failure mode so the manufacturer can help narrow the grade options.
Should I include inspection requirements in the first RFQ?
Yes. Inspection reports, certs, and traceability can affect lead time and quote assumptions.
Why include current part failure details?
Failure details reveal whether the design needs more wear resistance, toughness, corrosion resistance, or geometry changes.
