Characteristics of Cemented Carbide
1 High hardness and high thermal hardness. Good abrasion resistance. Therefore, when cemented carbide tools are in use, their cutting speed, wear resistance and average life are significantly higher than those of high-speed steel.
Commonly used cemented carbide
1 Tungsten-cobalt cemented carbide: The main components are tungsten carbide and cobalt. The initial code is used; the prefix ‘YG’ of the Chinese phonetic alphabet represented by the two characters ‘hard’ and ‘cobalt’ is indicated by adding a number, and the number indicates the percentage of cobalt content. For example, YG8, which means tungsten-cobalt cemented carbide, with a cobalt content of 8%
2 Tungsten-cobalt-titanium cemented carbide: its main component is tungsten carbide. Titanium carbide and cobalt. The code name is represented by the prefix ‘YT’ of the Chinese Pinyin letter of ‘hard’ and ‘titanium’ plus a number, and the number represents the percentage of titanium carbide. For example, YT5. Represents tungsten-cobalt-titanium cemented carbide. Containing titanium carbide 5%
