This concept of pre-alloyed powders offers both technical and economical advantages:

• NEXT® is cheaper than other traditional binders and offers a reduced cost due to low sintering temperatures
• excellent metal distribution on a much finer scale and greater homogeneity than other standard mixtures
• high protrusion and strong diamond retention with enhanced tool life and performance.

Pre-alloyed powders are composed of 3 metals: Cobalt, Iron and Copper. The range consists in 4 grades of pure NEXT® whose properties can be optimized by mixing with traditional additives.

Hardness as a function of sintering temperature (hot pressing)

NEXT®100

25% Co + 25% Fe + 50% Cu

• Cutting performances optimized by mixing with traditional additives.
• Recommended for blade superior to 500 mm.

NEXT®200

25% Co + 15% Fe + 60% Cu

• Exceptional free cutting ability.
• Recommended for blade inferior to 500 mm.

NEXT®300

25% Co + 72% Fe + 3% Cu

• Low copper content
• Designed for laser welding
• High ductility and high impact resistance.

NEXT®900

<4% Co + 80% Fe + 20% Cu

• Excellent combinaison with traditional additives.
• Good performances obtained for dry cutters and stone polishing.

Sintering temperatures

Sintering temperature	Pure NEXT®
	NEXT®100	NEXT®200	NEXT®300	NEXT®900
Minimum	825°C	700°C	775°C	825°C
Recommended for most applications	850°C	725°C	825°C	850°C

Main advantages:

• outstanding homogeneity and excellent dispersion in the bond
• optimization of tool performances
• premixed powders can be adapted to specific requirements by adding traditional additives

Binary premixed

MX1480

80% NEXT®100 + 20% Fe

• Fe powder increases ductility.
• Cutting performances optimised by mixing with traditionel additives.

MX1180

80% NEXT®100 + 20% WC

• WC powder increases abrasion resistance.
• For most grinding and polishing applications.

MX2480

80% NEXT®200 + 20% Fe

• Properties and performances very similar to NEXT®200.
• Optimized sawing performances of NEXT®200 when long blade life is required.

MX2180

80% NEXT®200 + 20% WC

MX3480

80% NEXT®300 + 20% Fe

• Excellent laser welding properties

Ternary premixed

MX1560

60% NEXT®100 + 20% Fe + 20% W

MX1660

60% NEXT®100 + 20% Fe+ 20% WC

• Good abrasion resistance without too much hardness.
• Mostly used for sawing of medium abrasive materials.

MX1760

60% NEXT®100 + 20% Fe+ 20% BR (85/15)

• Bronze increases the free cutting.

MX1770

70% NEXT®100 + 20% Fe + 10% BR (85/15)

Main advantages of NEXT® granules:

• NEXT® granules offer, after sintering, the same properties than non-granules NEXT® powders
• improved flow properties
• easy debinding
• very low generation of dust while handling.

Range of NEXT® powder available in granulated versions are:

• pure NEXT®: NEXT®101, NEXT®201, NEXT®301, NEXT®401
• NEXT® premixed: MX1181, MX1481, MX4885-1…
• Other premixed powder can be granulated upon request
