Manufacturing Capability
One Controlled Process Chain, From Powder to Precision Part
Keeping sintering, machining and finishing under one quality system reduces hand-offs between suppliers — the most common source of tolerance drift and lead-time risk in carbide sourcing.
01
Engineering Review
Drawings or samples are checked for grade, geometry, tolerance and manufacturability before production starts.
02
Sintering
Controlled sintering builds the density, hardness and microstructure the application requires.
03
CNC Machining
Complex features are machined on CNC equipment for repeatable geometry across batches.
04
Precision Grinding
Diamond grinding brings critical dimensions, flatness and edges into tight tolerance.
05
EDM
Wire and sinker EDM produce internal profiles and sharp details in hard materials.
06
Polishing & Inspection
Surfaces are polished to specification and parts are inspected before packing and export.

Buyer’s Material Guide
Which Material Fits Your Application?
A quick engineering reference our team uses during early project discussions. Use it to shortlist materials before sending your drawings.
| Material | Key Property | Typical Applications | Selection Tip |
|---|---|---|---|
| Tungsten Carbide (WC-Co) | Hardness approx. HRA 86–93, outstanding abrasion resistance | Cutting tools, dies, wear parts, shredder blades, mining tips | Lower cobalt for wear; higher cobalt for impact and toughness |
| Tungsten Heavy Alloy (W-Ni-Fe / W-Ni-Cu) | Density approx. 17.0–18.5 g/cm³, machinable | Counterweights, radiation shielding, vibration dampers | Choose W-Ni-Cu where a non-magnetic alloy is required |
| Tungsten Copper (W-Cu) | High thermal & electrical conductivity with arc resistance | EDM electrodes, welding electrodes, heat sinks | Higher copper content increases conductivity; higher tungsten improves erosion resistance |
| Molybdenum & Mo-Cu | Melting point 2,623 °C, low thermal expansion | Furnace hot zones, glass melting, electronic base plates | Mo-Cu balances thermal expansion with heat dissipation in packaging |
| Nickel Alloys (Inconel 625 / 718) | High-temperature strength and corrosion resistance | Aerospace, oil & gas, chemical processing, marine | 718 for high strength via age hardening; 625 for corrosion and weldability |
| Heating Elements | Stable resistance at elevated furnace temperatures | Industrial furnaces, kilns, laboratory heat treatment | Match element material to furnace atmosphere and maximum operating temperature |
Values are typical reference ranges. Final properties are confirmed per grade, drawing and application during technical review.

FAQ
Questions Procurement Teams Ask Before Their First Order
Clear answers to the most common sourcing questions about custom carbide and alloy components. Need something more specific? Our engineers respond to technical questions directly.
Contact Our EngineersCan FOTMA manufacture tungsten carbide parts from my drawing or sample?
Yes. FOTMA produces custom carbide components from 2D/3D drawings or physical samples. Our engineers review geometry, tolerances, grade and surface finish, then route the part through pressing, sintering, CNC machining, grinding, EDM and polishing as required.
How do I choose the right cemented carbide grade?
Grade selection balances hardness against toughness. Lower cobalt binder content (around 6%) gives higher hardness and wear resistance for abrasive applications, while higher cobalt content (around 10–15% or more) improves toughness for impact loads such as shredder blades and mining tools. Share your operating conditions and we will recommend a grade.
Which quality standard does FOTMA follow?
All production procedures, including sintering, CNC machining, grinding, EDM and polishing, are operated under an ISO 9001:2015 quality management system. Dimensional inspection records and material documentation are available on request.
What information should I provide for a technical review?
Please send drawings (PDF, DWG, STEP or IGES), material or grade requirements, tolerances, surface finish, annual volume and the application environment. This allows our engineers to confirm manufacturability and propose the most cost-effective process route.
Does FOTMA supply materials other than tungsten carbide?
Yes. In addition to cemented carbide, FOTMA supplies tungsten alloys, tungsten-copper and molybdenum-copper electronic packaging materials, molybdenum products, nickel and nickel alloys such as Inconel 625 and 718, heating elements, ceramic products and CNC machined parts.
