Hardfacing Types

AOS offers a complete range of Hardfacing to suit all drilling conditions.

HF 1000

Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF 2000

Trapezoid tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage ideal for high deviation drilling in abrasive formations.

HF 4000

Tungsten carbide inserts (button type). The inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.
