Introduction to YG6 Cemented Carbide YG6 cemented carbide is manufactured by low-pressure sintering of an ultra-fine grain (0.6 µm) alloy. It features a hardness of 93.0 HRA, a flexural strength of up to 3000 MPa, and an excellent combination of corrosion resistance, rust resistance, and wear resistance at a density of 14.8 g/cm³. This high-performance tungsten steel is ideal for producing quality cemented carbide tools for machining solid wood, chill-cast iron, hardened steel, PCBs, brake materials, and more. 2. Production Process The production process includes: • Batching → Thorough Mixing → Milling → Drying → Sieving, followed by the addition of a binder • Re-drying → Sieving to obtain the mixture → Granulation → Pressing → Sintering → Inspection (including non-destructive ultrasonic testing) → Verification of the blank's dimensional accuracy 3. Features and Applications of YG6 Cemented Carbide Products Utilizing an ultra-fine grain alloy (0.6 µm) with low-pressure sintering, YG6 achieves a high density of up to 14.8 g/cm³. It exhibits uniform grain distribution, excellent densification with no porosity or sand holes, and a homogeneous microstructure. With outstanding wear resistance and a high hardness of 93.0 HRA, its quality is stable and comparable to imported cemented carbide materials-indeed, some performance parameters even surpass those of similar imported products. It is recommended for use in turning tools, milling cutters, and tungsten steel drills for machining materials such as chill-cast iron, hardened steel, and brake materials. 4. Precautions for Using YG6 Cemented Carbide 1. Due to its high hardness and inherent brittleness, YG6 cemented carbide must not be struck during processing to avoid cracking, chipping, or edge collapse. 2. Cracking often occurs during online cutting of cemented carbide. Therefore, ensure that the machined surface is free from defects before proceeding to the next process step to guarantee product quality. 5. Advantages of the Configuration YG6 cemented carbide offers the following three main advantages: 1. It is produced using high-quality tungsten carbide and imported cobalt powder through hot isostatic pressing technology, ensuring standardized production with comprehensive performance superior to that of similar imported cemented carbides. 2. Its high hardness, balanced with moderate strength and excellent wear resistance, makes it an ideal material for manufacturing cemented carbide tools. 3. Product features include an optimized material grade and an exclusive formula for cemented carbide molds; complete specification range and precise blank dimensions (which reduce machining and improve production efficiency).
