Eurotungstene has built a world-wide reputation for technological leadership so it is hardly surprising that our innovative response for the diamond tool market is ahead of the field. The NEXT® revolution is today.
Derived from its on-going, high-level research and development programme and absolute expertise in powder metallurgy, NEXT® is the best substitute for cobalt. The top companies in the world agree. They have already adopted NEXT® and recognise its quality and industrial performance benefits.
To extend the impact of this technological revolution, Eurotungstene has now developed a range of six new very high quality, pre-mixed powders while continuing to offer the choice of pure or pre-mixed powders. Use all Eurotungstene's technological know-how and its technical support through our world-wide agency network and do not miss out on the technical revolution for the third miliennium.

NEXT® the first range of submicronic prealloyed powders, is now recognized as the alternative solution and more and more diamond tools producers are incorporating it in their manufacturing process.
NEXT® is suitable for all the diamond tools applications such as saw blades, wire saws, core drills, polishing tools...
Moreover, mixing NEXT® with traditional additives, the diamond tools producers can achieve the optimum adaptation of the bond to the specificity of the worked materials.
Now, Eurotungstene, offers a complementary range of pre-mixed powders, consisting in mixtures of NEXT®100 and NEXT®200 with additives.
The addition of iron (20%) to NEXT®100 causes an increase of the limit of elasticy, that is obtainable by sintering at a temperature of only 700°C. A high value of this limit is an important factor for the diamond resistance. Both in the case of NEXT®100 and NEXT®200, the resistance at the impact sensibly improve with the addition of iron; this property is always reachable at only 700°C. The addition of WC (tungsten carbide) to NEXT® increases its hardness and its wear resistance, with consequent increase of the blade life.
Adding iron and tungsten, together, or iron and tungsten carbide, the higher resistance at the wear due to W and WC is joined at the positive effects of iron on the mechanical properties of NEXT®100. With these three components pre-mixed powders, a high wear resistance can be achived at a significantly lower sintering temperature than with cobalt based bonds.
NEXT® powders give results at least comparable to those obtanaible with cobalt, but with cheaper cost and lower sintering temperature. |
