HARTMETALL ESTECH has also developed two new hard metal grades with alternative binding agents, namely on the basis of iron/nickel/cobalt alloys.
伊斯泰克硬質合金公司開發了兩種新的牌號，這個牌號的粘結劑不僅是鈷，而是鐵-鎳-鈷合金。

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 是由非常均勻的亞微米顆粒的碳化鎢粉和 10%的鐵-鎳-鈷粉作為粘結劑燒結而成。在保持高硬度的前提下，大幅度提高了斷裂韌性和耐磨性。可以使用電火花加工這個牌號。優異的性能可以制作耐磨零件、堅韌材料的精沖、刀片，特別在加工溫度低于500度的塑料、木材和造紙工業中作為鉆銑工具表現出色。HARTMETALL ESTECH 備有RXE20棒料的庫存。 |
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具有相似的結構，但具有兩倍的粘結劑，因此增加了斷裂韌性和抗彎強度。在沖壓、模具和擠壓工具行業使用，用于處理高韌性材料，木材和紙的行業，在500℃的加工溫度下具有良好的表現。HARTMETALL ESTECH有RXE40牌號的毛坯和精磨長圓棒的庫存和方條庫存。 |
