SARO wear-resistant alumina: advanced solutions for abrasion and erosion protection
Alumina (aluminum oxide - Al2O3) represents one of the highest-performing ceramic materials used in anti-wear industrial applications, thanks to its extremely high hardness, abrasion resistance, and its ability to operate in environments characterized by severe mechanical stress and continuous erosion.
In industrial processes for handling bulk, granular, and powdered materials, alumina is used to protect components and surfaces subject to intense wear caused by:
- continuous impact of the material
- high-velocity flow erosion
- abrasion from highly aggressive dust and granules
The applications concern in particular:
- Piping and bends for pneumatic conveying
- Cyclones and separators
- Slides, chutes, and channels
- Deviators and valves
- silos and storage systems
- transport lines for abrasive materials
Thanks to the various purity grades available (92%, 95%, and higher), alumina solutions allow wear resistance to be tailored to the specific operating conditions of the plant, ensuring high reliability and a long service life.
Among the main advantages of wear-resistant alumina:
- very high abrasion resistance
- High chemical inertia (the only enemy is Hydrofluoric Acid)
- Excellent thermal resistance
- long operating life even in extreme conditions
