APPLICATION

Valve Rotor

SECTOR
  • Pumps and Compressors
GRADE
SUITABLE TO REPLACE
  • Steel
  • Sand Castings
ADVANTAGES
  • Better machinability (using spheroidal graphite)
  • Higher tensile strength (using spheroidal graphite)
  • Higher wear resistance
  • Better surface finish
  • Less weight
  • Reduces metal friction
  • Quieter running – absorbs vibration
  • Scrap reduction
  • Shorter deburring time
  • Good vibrational absorption
  • No shrinkage or porosity
COST SAVING
  • No pattern costs
  • No rejected parts
  • Extended tool life because of no sand inclusions and self lubricating properties
  • Smaller machining allowance
