What Kinds Of Metal Used In Roll Forming

Roll forming can shape any ferrous or non-ferrous metals and their alloys. The types of metals used by manufacturers determine the adjustments that must be made to each bending stage of the roll forming process. The key factors are thickness and ductility as well as the flow stress, which determines the amount of force necessary to shape the metal. The yield point, the point at which a metal bends, is higher at a lower temperature necessitating an increase in the amount of force, which has to be factored into the roll forming machine.

Listed below are seven metals that are commonly used in roll forming separated into ferrous and non-ferrous metals.

Ferrous metals – Contains iron

Steel:

  • Made of iron
  • Malleable below its melting point without requiring special heat treatment.
  • Free from slag
  • Contains small amounts of silicon and manganese
  • Has trace quantities of sulfur and phosphorus

Stainless Steel:

  • Has a high percentage of chromium
  • Strain and corrosion resistant
  • Resistant to weak mineral acids, oxidation, organic acids, and caustic materials
 

Galvanized Steel:

  • Coated with zinc
  • Is a heat-treated metal
  • Has a bonded coating of zinc-iron alloy
 

Non-Ferrous metals – Does not contain iron

Aluminum:

  • Malleable
  • Lightweight
  • Resistant to corrosion
  • Has a layer of aluminum oxide
 

Brass:

  • Copper and zinc alloy
  • Corrosion-resistant
  • Bronze is another type
  • Malleable

Copper:

  • Has electrical conductivity.
  • The primary component in non-ferrous alloys
 

Lead:

  • Has high density
  • Low melting point
  • Tarnishes slowly
  • Ductile
  • Poor electrical conductor
  • Resistant to corrosion
