YG alloys are mainly used for processing cast iron, nonferrous metals and non-metallic materials. Fine-grained cemented carbides (such as YG3X and YG6X) have higher hardness and wear resistance than medium-grained ones when the cobalt content is the same, and are suitable for processing some special hard cast iron, austenitic stainless steel, heat-resistant alloys, titanium alloys, hard bronze and wear-resistant insulating materials.

The outstanding advantages of YT cemented carbides are high hardness, good heat resistance, higher hardness and compressive strength at high temperatures than YG, and good oxidation resistance. Therefore, when the knife is required to have higher heat resistance and wear resistance, a grade with a higher TiC content should be selected. YT alloys are suitable for processing plastic materials such as steel, but not for processing titanium alloys and silicon-aluminum alloys.

YW alloys have the properties of both YG and YT alloys, and have good comprehensive performance. They can be used for processing steel, cast iron and nonferrous metals. If the cobalt content of this type of alloy is appropriately increased, the strength can be very high, and it can be used for rough processing and intermittent cutting of various difficult-to-process materials.
