HARTMETALL ESTECH has also developed two new hard metal grades with alternative binding agents, namely on the basis of iron/nickel/cobalt alloys.
伊斯泰克硬质合金公司开发了两种新的牌号，这个牌号的粘结剂不仅是钴，而是铁-镍-钴合金。

RXE20 | 10.0 | RXE20 consists of a very homogeneous submicron tungsten carbide grain and 10% iron/nickel/cobalt binder agent. We thus combined a high hardness and wear resistance with excellent fracture toughness. This grade of cemented carbide can be processed using wire and sink EDM. Excellent for use in wear protection, in fine punching of tough foils and metal sheets, and as blades, milling tools and drills in the plastic, wood and paper processing industries at temperature ＜500℃ HARTMETALL ESTECH possesses a stock program of Long round rods in RXE20. RXE20 是由非常均匀的亚微米颗粒的碳化钨粉和 10%的铁-镍-钴粉作为粘结剂烧结而成。在保持高硬度的前提下，大幅度提高了断裂韧性和耐磨性。可以使用电火花加工这个牌号。优异的性能可以制作耐磨零件、坚韧材料的精冲、刀片，特别在加工温度低于500度的塑料、木材和造纸工业中作为钻铣工具表现出色。HARTMETALL ESTECH 备有RXE20棒料的库存。 |
RXE40 | 20.0 | RXE40 has a similar structure as RXE20, but with the double percentage of the binding agent. We thus Increase the breaking resistance and the fracture Toughness. Use in punching stamps, dies and pressing tools, for processing highly tough materials, and in the wood and paper industry, at application temperatures of up to 500℃maximum. HARTMETALL ESTECH has stocks of long round rods as sintered or h6 and square rods in this hard metal grade. RXE40 和RXE20具有相似的结构，但具有两倍的粘结剂，因此增加了断裂韧性和抗弯强度。在冲压、模具和挤压工具行业使用，用于处理高韧性材料，木材和纸的行业，在500℃的加工温度下具有良好的表现。HARTMETALL ESTECH有RXE40牌号的毛坯和精磨长圆棒的库存和方条库存。 |
