Cemented Carbide Parabolic Buttons

Cemented carbide parabolic buttons are the main parts of road digging machine-milling machine which are mainly used for the protection and repairing of roads. Only cemented carbide parabolic buttons have good hardness and impact resistance can the milling machine work efficiently. Chinatungsten Online can provide various sizes of cemented carbide parabolic buttons according to customers' specific requirements.

Cemented carbide parabolic buttons are sinters from WC-Co powder with low pressure. With properties of good wear resistance, impact resistance and long service life, cemented carbide parabolic buttons are widely applied in the construction of airport, wharf, express way,etc.

Advantages of cemented carbide parabolic buttons from Chinatungsten Online:

1.The metallographic structure of cemented carbide parabolic buttons is tight, effectively reducing the microscopic pores in the alloy.

2.Cemented carbide parabolic buttons have good toughness, strong resistance to high temperature and high wear resistance and its service life is generally 5 to 20 times longer than parabolic buttons made from other materials.

3.Good quality and reasonable price of cemented carbide parabolic buttons from Chinatungsten Online.
