Advantages of Tungsten Carbide Bushings:
Abrasive resistant,corrosion free,good compression property,the most wear-resistant bushing ,heat resistance,low maintenance
The hardness is 10 times of gold,5 times of tool steel, 4 times of titanium , oil resistance, separate the harmful medium
No shape change or twist when temparature is above 1000 °C or below 500 °C, long service life , the maximum height can reach 270mm.
High precision,whose tolerance can be +/-0.002mm.
HIP processed.
Professional designed moulds to get complicated shape and high precision tolerances.
