Ultra-fine grain carbides are characterized by a very high hardness and wear resistance.
They are used for milling tools and drills for processing abrasive, soft and tough materials, in nozzles and in wear protection parts.
超细牌号具有高硬度和良好的耐磨性的特点。
这些牌号用于加工用的铣削和钻头工具，软而粘的材料，喷嘴，和耐磨零件。
WC grain size ultra-fine, 0.5-0.7μm

RX8UF | 8.0 | This very hard grade is used particularly for manufacturing vibration-free rotating tools for processing Aluminum, copper, silver, gold, graphite and glass-fiber-reinforced plastics (GFP). 这种超硬材料特别适用于制造用来加工铝、 铜、 银、 金、 石墨、 玻璃纤维增强塑料 (GFP)的无振动旋转工具。 |
RX12UF | 12.0 | Due to its higher cobalt content, this grade is suitable for machining high and low alloyed steels, cast iron, titanium and many other materials at a higher feed rate. Also ideal for high speed milling. Especially suitable for the mould construction. 由于其较高的钴含量，这种牌号在高进给量条件下，适合加工高、 低合金钢、 铸铁、 钛和许多其他材料。也适合于高速铣削加工，特别适用于模具制造。 |
Submicro grain cemented carbides are our most frequently used grain size class. The very homogeneous, fine microstructure of this grade allows for high hardness and cutting abilities and is excellently suited for machining and milling tools, drills, guides, cutting tools, pressing dies, in wear protection and even for fine punching tools.
我们常用的组成硬质合金的微粒规格一般是亚微米级。这种均匀、 细微的结构可以赋予材料很高的硬度和优秀的切割能力，非常适合加工和铣削工具、 钻头、 导轨、 切削刀具、 冲压模具的磨损保护，以及甚至细冲压工具。
WC grain size submicron, 0.7-0.9mm
颗粒度：亚微米

RX3 | 3.3 | Our so far hardest carbide is relatively break and impact sensitive due to its low cobalt content, and is not suitable for machining tools. In contrast, this type is used for sand blasting nozzles, spray nozzles and similar applications, drawing dies for soft metals, or in wear protection for linings against abrasive wear. 目前为止很硬的牌号，由于其含钴量低，不耐冲击，容易崩裂，不适合制作工具。适用于喷砂嘴、喷嘴和类似的其他用途，适用于软金属的拉丝模，或对衬片的磨损保护。 |
RX6 | 6.0 | Very hard, easy cutting grade for machining, milling, drilling and lathing of aluminum, copper, silver, gold, graphite and glass-fiber- reinforced plastics (GFP). Also used in wear protection. 硬度高，易于做切削加工、 铣、 钻、 车削的牌号。适合材料：铝、 铜、 银、 金、 石墨、 玻璃纤维增强塑料 (GFP)，也用于耐磨零件。 |
RX7 | 7.5 | Very hard, well cutting grade for machining aluminum, copper, silver, certain types of steel, graphite and glass-fiber- reinforced plastics (GFP) with increased breaking resistance and edge stability. Also used for wood processing. 很硬，相对RX6有更好的抗裂强度和切面强度。切削加工铝，铜，银，某些类型的钢，石墨，玻璃纤维增强塑料 (GFP)和木材的初选牌号。 |
RX10 | 10.0 | This most important submicron grade offers a balanced ratio between high hardness and good breaking resistance and is therefore suitable for all types of machining, milling, drilling and lathing tools for processing high and low alloyed steels, cast iron, titanium and non-iron metals; in pressing dies, drawing dies, in wear protection and in tools for fine punching thin sheets. Standard grade for T-slot cutters. Manufacture of guides for the sheet processing industry. 是重要的亚微米级牌号。硬度高，抗裂强度好，适用于所有类型的加工铣、钻、 车等加工，可以加工高合金钢、 低合金钢、 铸铁、 钛和非铁金属；适用于冲压模具、拉伸模，耐磨零件和精冲工具。是T 形槽铣刀的标准牌号。可用于板材加工行业的导轨。 |
RX15 | 15.0 | The high cobalt content of this submicron grade brings an increased level of toughness of the material. RX15 is suitable for machining at an interrupted cut, for paper cutting blades and for fine punching of thin sheets of medium to high toughness. 钴含量高，材料韧性好。适合断续切削加工、 裁纸刀、中高韧性薄板的精冲。 |
