NT® Nickel-based metal powders
| BRAND NT® | Weld metal standard analysis % |
Hardness | Applications and properties | Process | |
| NT® Ni20 | C Si B Fe |
< 0,2 2,5 1,5 < 1,0 |
20 HRC | Self-flowing NiBSi alloy with a low hardness value for the repair of cast iron machine components, such as valves and fittings, sealing seats, cylinder heads, valve seats, shaft-protector sleeves, sealing clacks and gates, elbows, pump components, pulleys and rolls, etc.; very easily workable and machinable | PTA PS HVOF |
| NT® Ni25 | C Si B Fe |
< 0,5 2,5 1,7 < 1,0 |
25 HRC | Similar to NT® Ni40, but with increased hardness of 25 HRC because of the higher contents of C and B | PTA PS HVOF |
| NT® Ni35 | C Si B Cr Fe |
0,3 3,5 1,3 6,0 2,0 |
33 HRC | Self-flowing NiCrBSi alloy with good thermal, mechanical and corrosion-resistant properties; recommended applications: valves, pump components, guide pulleys, glass moulds, etc. | PTA PS HVOF |
| NT® Ni40 | C Si B Cr Fe |
0,25 3,5 1,3 6,0 2,0 |
42 HRC 600°C 220 HV |
High shock resistance, very effective protection against abrasive and seizing wear, as well as corrosion, und also easy machinability; hard facing of surfaces or edges on forging dies, glass moulds, as well as valves and fittings, pump pistons, and guiding devices | PTA PS HVOF |
| NT® Ni50 | C Si B Cr Fe |
0,45 3,8 2,3 11 2,5 |
52 HRC 600°C 278 HV |
Self-flowing, hard NiCrBSi alloy for the application of corrosion- and wear-resistant claddings; still capable of machining | PTA PS HVOF |
| NT® Ni60 | C Si B Cr Fe |
1,0 4,0 3,2 15,0 4,0 |
60 HRC 600°C 370 HV |
Hard, nickel-based alloy with extremely high resistance to wear and corrosion, such as that resulting from the presence of chromium and borides as well as carbides; low coefficient of friction | PTA PS HVOF |
| NT® NiBSi | C Si B Fe |
< 0,03 3,0 3,0 < 0,4 |
50 HRC | Hard, chromium-free nickel alloy with good wetting and flow properties; very well suited for use as matrix material in pseudo-alloys (reinforcement by carbides) | PTA PS HVOF |
| NT® NiAl 95 5 | C Al |
< 0,03 5 |
- | For use as primer in thermal spraying | PTA PS HVOF |
| NT® NiCr 80 20 | C Si Cr |
0,1 0,6 20,0 |
170 HB |
High resistance to high-temperature oxidation and to corrosion in many media; also ideal for use as moderating layer before the application of hard cover passes for avoiding or reducing crack formation |
PTA PS HVOF |
| NT® NiCr70Nb | C Si Cr Fe Mn Nb |
< 0,03 0,3 20,0 1,5 3,0 2,5 |
170 HB | Suited for the application of moderating layers – properties similar to those of NiCr 80 20 | PTA PS HVOF |
