Can you supply custom grades or particle size distributions?
Yes. MEPOSO can discuss chemistry, morphology, particle size and apparent density targets according to the industrial application and production process.
Pre-alloyed iron-copper bond powder for diamond beads, cutting segments, gang saw tools, rollers and fickerts.
CULNICO® EXP11 is a pre-alloyed iron-copper bond powder with a higher copper range than EXP10. It keeps tin in the system while reducing nickel and phosphorus, making it a practical option when the manufacturer wants to assess a softer or more copper-driven matrix balance within the same tool family.
It is used on diamond beads, cutting segments, gang saw tools, rollers and fickerts when the technical objective is to compare hardness, wear behaviour and process response against another ready-made bond chemistry, without changing the overall production logic.
CULNICO® EXP11 is positioned as an iron-copper bond with tin and reduced nickel-phosphorus content. The chemistry window below defines how the grade is balanced for qualification and process comparison.
| Code | Fe | Cu | Sn | Ni | P |
|---|---|---|---|---|---|
| CULNICO® EXP11 | remainder | 30 - 40 % | 4 - 10 % | < 5 % | < 3 % |
| Oxygen content | 0.5 % | ||||
| Route | Compaction | Sintering | Speed / Time | Hardness | Density |
|---|---|---|---|---|---|
| Free sintering | 62 / 65 % | 700 / 900 / 950 C | Belt speed 5 cm/min | 99 HRB | 8.3 |
| Hot pressing | 350 Kg/mm² | 700 / 750 C | 180 / 200 sec. | 99 HRB | 8.3 |
