Reiloy barrels

Armouring alloys for bimetal barrels.

Reiloy top alloys for bimetallic barrels provide optimum protection against wear and corrosion in your production. The blanks are absolutely torsion-free because they are manufactured on inductive centrifugal casting plants with integrated process control developed inhouse.


Versions
From blank barrel to finished product.

Blank barrel

  • Bore finish honed to H7
  • Outside diameter and length with machining allowance

Semi-finished barrel

  • Bore finish honed to H7
  • Outside diameter and length machined to measure (if desired including feed opening)
  • if needed with shrink sleeve on the discharge side

Finished barrel

  • Finished product according to drawing
