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.
超細牌號具有高硬度和良好的耐磨性的特點。
這些牌號用于加工用的銑削和鉆頭工具，軟而粘的材料，噴嘴，和耐磨零件。
WC grain size ultra-fine, 0.5-0.7μm
顆粒度：超細
grade | Cobalt content %w/w | Properties and recommendations

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). 這種超硬材料特別適用于制造用來加工鋁、 銅、 銀、 金、 石墨、 玻璃纖維增強塑料 (GFP)的無振動旋轉工具。 |
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. 由于其較高的鈷含量，這種牌號在高進給量條件下，適合加工高、 低合金鋼、 鑄鐵、 鈦和許多其他材料。也適合于高速銑削加工，特別適用于模具制造。 |
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.
我們常用的組成硬質合金的微粒規格一般是亞微米級。這種均勻、 細微的結構可以賦予材料很高的硬度和優秀的切割能力，非常適合加工和銑削工具、 鉆頭、 導軌、 切削刀具、 沖壓模具的磨損保護，以及甚至細沖壓工具。
WC grain size submicron, 0.7-0.9mm
顆粒度：亞微米

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. 目前為止很硬的牌號，由于其含鈷量低，不耐沖擊，容易崩裂，不適合制作工具。適用于噴砂嘴、噴嘴和類似的其他用途，適用于軟金屬的拉絲模，或對襯片的磨損保護。 |
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、 銑、 鉆、 車削的牌號。適合材料：鋁、 銅、 銀、 金、 石墨、 玻璃纖維增強塑料 (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，相對RX6有更好的抗裂強度和切面強度。切削加工鋁，銅，銀，某些類型的鋼，石墨，玻璃纖維增強塑料 (GFP)和木材的初選牌號。 |
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. 是重要的亞微米級牌號。硬度高，抗裂強度好，適用于所有類型的加工銑、鉆、 車等加工，可以加工高合金鋼、 低合金鋼、 鑄鐵、 鈦和非鐵金屬；適用于沖壓模具、拉伸模，耐磨零件和精沖工具。是T 形槽銑刀的標準牌號。可用于板材加工行業的導軌。 |
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. 鈷含量高，材料韌性好。適合斷續切削加工、 裁紙刀、中高韌性薄板的精沖。 |
