  • Strict dimensional tolerance and surface finish control

Machinable materials include tungsten carbide, mold steel, tool steel, copper, as well as other metals and ceramic materials.

How to Choose the Tungsten Carbide Grade for Bushings

Custom carbide bushings are typically manufactured using tungsten carbide grades with properties similar to ISO K-series, with a focus on wear resistance, hardness, and dimensional stability under load. Compared to nozzle applications, bushings often operate under combined conditions such as sliding wear, friction, pressure load, and potential impact.

Depending on application requirements, such as shaft speed, load conditions, lubrication, working media, and service life expectations, different cobalt binder contents (e.g., K10–K40 equivalent) are selected to balance wear resistance and toughness. Lower cobalt grades provide higher hardness and wear resistance for low-impact conditions, while higher cobalt grades offer improved toughness and resistance to cracking or chipping under heavy load or misalignment.

Corresponding Chinese tungsten carbide grades. For example, K10 corresponds approximately to YG6 (high wear resistance), K20 to YG8 (general purpose), and K30–K40 to YG10–YG15 (higher toughness grades). Final grade selection depends on wear conditions, impact load, and service life requirements.

K10, K15, K20, K30, K40 Grade Equivalency Table (YG6, YG8, YG10, YG15)

ISO Grade General Characteristics Common Chinese Grade Reference
K10 High hardness, low cobalt content, excellent wear resistance YG6 / YG6X
K15 Slightly improved toughness while maintaining good wear resistance YG6X / YG8X
K20 General-purpose grade with balanced wear resistance and toughness YG8
K30 Better toughness and impact resistance YG10 / YG10X
K40 High toughness and high cobalt content, suitable for higher impact conditions YG13 / YG15
