RF13 | 6.5 | This grade is used for manufacturing cemented carbide slitting and milling disks and circular saw blades, for cutting inserts, nozzles, guides, bushings and linear blades, with low impact, and is also suitable for woodworking tools. For lathing, milling, drilling, reaming and countersinking of hardened steels, hard and grey cast iron, light metal, aluminum, Si-, Cu-, Mn-alloys, plastics, glass, ceramics and graphite.
用于制造锯片铣刀和圆锯片，数控刀片、喷嘴、导轨、衬套及线刀，也适合木工工具。为车削、铣削、钻铰孔、淬火钢，硬钢和灰色铸铁、轻金属，铝，硅-铜-锰合金、塑料、玻璃、陶瓷和石墨。 |
RF24 | 12.0 | This fine grade of medium cobalt content is used for the manufacturing of cutting rings, slide rings, blades, guides, bushings, lathe tips, dies, drawing and pressing tools.
含钴量中等，用于制造切割环、滑环、刀片、导轨、衬套、车刀，模具、拉丝和冲压工具。 |
RF40 | 20.0 | This hard metal grade contains a high percentage of cobalt binder and is therefore suitable for tools subject to high impact stresses such as hammer jaws, reshaping tools, stamping tools.
含钴量很高。因此适合于承受高冲击力的工具，如锤卡爪，矫形工具，冲压工具。 |
RF54 | 27.0 | This grade contains the maximum possible cobalt binder content and is characterized by a very high fracture toughness and transverse rupture strength and is therefore highly impact-resistant. It is used in tools for hot and cold forming, for manufacturing steels springs, in hammer jaws and in shredders.
含钴量高，具有很高的断裂韧性和横向断裂强度，因此非常耐冲击。它用于热成型和冷成型的工具，如制造弹簧钢，锤爪，碎纸机。 |
These cemented carbide grades with medium grain size combine good hardness and wear resistance with high transverse rupture strength, fracture toughness and thermal shock resistance. Application in general wear protection, for guides, bushings, slide rings, cutting rings, blades, and lathe tips, reshaping, rolling, drawing and pressing tools.
这些硬质合金牌号的硬质合金粒度为中等，具有高硬度、高耐磨性、好的横向断裂强度、好的断裂韧性和抗热震性。一般用于耐磨零件，导轨、衬套、滑环、切割环、刀片、车刀、塑形、 轧辊、拉伸和冲压工具。
WC grain size medium, 2.2-2.8μm
WC 晶粒度 中等，2.2-2.8μm

RM13 | 6.5 | This grade has been developed for the manufacturing of guides, bushings, valve fittings, balls, blades, rotary burrs, subject to relatively low impact stresses, and is also suitable for woodworking tools. Can be used for somewhat higher toughness requirements and for interrupted cuts instead of our grade RF13.
在承受相对较低的冲击应力时，可以用于导轨、衬套、阀门配件、球、刀片、旋转锉，也适合木工工具。在要求较高韧性要求的断续切削工况下，优于RF13。 |
RM16 | 8.5 | This hard metal grade in used for guides, bushings, cutting rings, cutting wheels, blades, lathe tips, grinding balls, valve fittings, plungers, slide rings, mandrels, mixers, impact bodies, deburrers, peeling tools and rotary burrs.
用于导轨、 轴套、 切割环、 切割片、刀片、车刀，磨球、阀门配件、柱塞、滑环、心轴、 搅拌机，冲击零件，去毛刺机，剥皮刀和旋转锉。 |
RM22 | 11.0 | This grade with medium binder content ideally combines hardness and breaking resistance and is often used for initial equipping. In particular, it is used to manufacture dies, punches, valve fittings, cutting rings, slide rings, shaft sleeves, grinding mandrels, guides, bushings, sensor capsules, lathe tips, drawings and pressing tools.
中等粘结剂含量，理想的硬度和抗弯强度。用来制造模具、冲头、阀门配件、切割环，滑环、轴磨削心轴、导轨、衬套、传感器触头、车刀、拉深和挤压工具。 |
RM30 | 15.0 | The somewhat higher cobalt content of this grade in comparison to RM22 improves the breaking resistance and the fracture toughness. It is therefore used in more sensitive tools and applications, such as dies, bending and reshaping tools, drawing tools, embossing stamps, tracers and shredders.
这个牌号具有稍高的钴含量。与RM22 相比提高了抗折力和断裂韧性。它因此用于更敏感的工具和应用，如模具、弯曲和塑形工具，拉伸模，轧花、示踪剂和破碎机。 |
