The Ultimate Overview of Metal Forming

Metal forming is crucial in various industries, including agriculture, heavy equipment, construction, and manufacturing, as they allow the creation of intricate parts and components with precise specifications and desired mechanical properties. These techniques can be used with a wide range of metals, including steel, aluminum, copper, and alloys, to fulfill diverse industrial needs.

What Is Metal Forming?

Metal forming is a manufacturing process that involves shaping metal into different forms and structures. It encompasses a variety of techniques used to manipulate metal into desired shapes, sizes, and configurations. Some common methods of metal forming include casting, forging, rolling, extrusion, and stamping.

Different metal forming processes have their own advantages and applications, and the choice of technique depends on factors like the type of metal material being used, the desired shape, tolerances, and production volume. Metal forming techniques are essential in various industries, including automotive, aerospace, construction, and manufacturing.

Understanding and controlling tensile stresses are key to achieving desired shapes and minimizing defects during the manufacturing process. Optimizing the distribution of stresses helps prevent defects like tearing, wrinkling, or thinning of the material, enhancing the formability of the metal.

Common Types of Metal Forming Processes

There are various techniques for metal forming, each suitable for different types of metals and end products. Some of the most common types of methods include:


Metal forging is a manufacturing process that involves shaping metal by applying pressure through controlled heating and hammering or pressing, creating a high strength and structurally secure product. Forging includes hot forging, cold forging, closed die forging, open die forging, and more.


Ideal for complex parts and large volumes, metal casting involves pouring molten metal or liquid metal into a die to obtain the desired shape. Once cooled and solidified, the metal takes the form of the mold. Casting processes include die casting, investment casting, sand casting, and more.


Also called roll forming, this metal forming process utilizes rollers to form sheet metal by passing the metal between two rollers. The process typically occurs at elevated temperatures (hot rolling) or room temperature (cold rolling), each offering distinct advantages based on the material properties and intended outcome.


Pulling metal through a die to reduce its diameter or change its shape. It involves elongating the metal piece by forcing it through a constricted or shaped orifice, resulting in a thinner and elongated final product. The deep drawing method is often used in making wires, tubes, and other long, slender forms.


Forces metal through a shaped die to produce long pieces with a consistent cross-section. Metal extrusion is commonly used in creating rods, bars, complex structural shapes, and hollow shapes. The Federal Group specializes in aluminum and brass extrusion to satisfy your desired cross section.


This metal forming process involves applying pressure to a metal workpiece to form it into a specific shape using mechanical or hydraulic presses. Ideal for smaller runs, metal pressing includes metal bending which uses a machine called a press brake to form sheet metal.

Several metals and alloys are commonly used in the metal forming processes, depending on the specific application and desired properties. Some of the most frequently utilized metals include:

  • Steel: Known for its strength, versatility, and affordability, steel is extensively used in various forms (carbon steel, stainless steel, etc.) across industries like automotive, construction, and manufacturing.
  • Aluminum: Lightweight yet strong, aluminum is used in aerospace, automotive, and construction due to its corrosion resistance and excellent formability.
  • Copper: Valued for its electrical conductivity and malleability, copper is used in electrical wiring, plumbing, and certain industrial applications.
  • Brass: A combination of copper and zinc, brass is utilized for decorative purposes, fittings, valves, and instruments due to its attractive appearance and corrosion resistance.
  • Titanium: Known for its exceptional strength-to-weight ratio and resistance to corrosion, titanium finds applications in aerospace, medical implants, and high-performance machinery.
  • Nickel: Often used in alloys, nickel provides heat resistance and corrosion resistance, making it valuable in aerospace, chemical, and electronics industries.
  • Magnesium: Known for its lightweight properties, magnesium is used in aerospace, automotive, and electronics industries for parts where weight reduction is crucial.
  • Custom Alloys and Other Metals: Alloying metals together, such as brass (copper and zinc), bronze (copper and tin), and various steel alloys (e.g., stainless steel), allows for tailoring properties like strength, corrosion resistance, and conductivity to meet specific requirements across different applications.

Different metals offer varying strengths, corrosion resistance, conductivity, and other mechanical properties that make them suitable for specific applications. The choice of metal depends on factors like the intended use, required properties, and the manufacturing process itself.
