What is Forging?
Forging is a manufacturing process where metal is shaped by applying extreme pressure through pressing, pounding, or squeezing—usually while the metal is hot. Unlike casting, where metal is melted and poured into molds, forging involves solid metal that is heated and then formed into high-strength parts known as forgings. This process improves the structural integrity of the metal, making it stronger and more reliable.
Why Use Forgings, and Where Are They Found?
Forgings are known for their superior strength, toughness, and resistance to impact. Because of these qualities, they are widely used in applications where reliability and safety are critical—though you might not see them directly. Forged components are typically hidden inside larger assemblies like:
·
Airplanes
·
·
Automobiles
·
·
Tractors
·
·
Ships
·
·
Oil drilling equipment
·
·
Engines
·
·
Missiles
·
·
Heavy industrial machinery

Common Metals Used in Forging
Nearly any metal can be forged, but the most commonly used include:
·
Carbon, alloy, and stainless steels – Strong and versatile
·
·
Tool steels – Extremely hard, used for cutting and shaping tools
·
·
Aluminum – Lightweight and corrosion-resistant
·
·
Titanium – High strength-to-weight ratio, ideal for aerospace
·
·
Brass and copper – Good electrical conductivity
·
·
High-temperature alloys – Contain cobalt, nickel, or molybdenum; used in extreme environments
·
Forging Equipment Types
Different forging methods require different equipment. Common types include:
·
Hammers – Deliver rapid, high-pressure blows (up to 50,000 lbs) to shape the metal
·
·
Presses – Apply steady, high-pressure force vertically (up to 50,000 tons)
·
·
Upsetters – Similar to presses but used horizontally for upsetting operations
·
·
Ring Rollers – Form seamless rings by compressing hollow metal rounds under rotating pressure
