Brown Fused Alumina for Drilling Components
Enhancing wear and erosion resistance in oil, gas, and geothermal drilling assemblies.
Why Use BFA in Drilling Hardware?
Drilling tools operate in harsh, abrasive, and high-pressure environments. Brown fused alumina (BFA) is incorporated into ceramic coatings, inserts, and linings for drilling components due to its high hardness, chemical inertness, and thermal resistance. It helps reduce wear, erosion, and equipment failure in downhole and surface operations.
- Mohs hardness 9.0 for severe abrasive conditions
- Stable under high-pressure and high-temperature (HPHT) conditions
- Corrosion-resistant and compatible with drilling fluids
Drilling-Grade Applications
- Ceramic-reinforced drill bit nozzles and jets
- Stabilizer sleeves and wear pads
- Rotary steerable system (RSS) liners
- Guide bushings and valve seals in mud motors
Widely used in oilfield drilling, HDD (horizontal directional drilling), and geothermal exploration.
Recommended Forms & Sizes
- Wear-resistant inserts & ceramics: 0.5–3 mm crushed grain
- Thermal spray or coating matrix: F46–F120
- Precision sealing surfaces: F150–F320 microgrits
