Product Description

YG11C Cemented Tungsten Carbide Mining Bits For Construction Purpose

YG11C Cemented Carbide Insert and Blades for Construction Purpose


Prodcut Descriptions :

Cemented carbide, or WC, has a number of unique and impressive characteristics, the most significant being the ability to resist abrasion. It is the hardest metal known to man. Sintered and finished carbide has a combination of compressive strength, extreme hot hardness at high temperatures, and resistance to abrasion, corrosion and thermal shock. Cemented carbide tunnel borer carbide tips are made of cemented carbide will remain the advantage of cemented carbide which is of wear resistance, hardness and corrosion.

Our tunnel borer carbide tips can be used in the urban underground rail transportation, railway tunnel, river-crossing sea-crossing tunnel and hydropower project construction.
