Metal forming extrusion is the process used to fabricate parts of uniform cross sections by squeezing the metal through a high pressure outlet. The extruded metal is shaped by a die. Metals that are extruded include lead, tin, aluminum, copper, brass and steel. Some metals are extruded cold, while heat is required for others.

If you need a customized part, consider aluminum. Aluminum extrusions total 50% of the total extruded metals market. Aluminum is more cost effective, flexible, anticorrosive, lightweight and has more thermal conductivity properties than other metals.

Other common metal extrusion applications include the following:

1. Copper tubing for refrigeration and plumbing

2. Aluminum extrusions for a variety of industrial applications

3. Stainless steel extrusion for structural products


Action Steps
The best contacts and resources to help you get it done

Use custom metal extrusions made from copper for plumbing and refrigeration applications


Extruded copper products are used in air conditioning and refrigeration, geothermal heating and cooling systems, domestic plumbing and water distribution and fire sprinkler systems.

I recommend: Weldaloy products offers custom metal extrusion services for all heating and cooling applications that use copper tubes and fittings. Electric Materials specializes in copper tubing for refrigeration. Grainger offers an array of extruded copper products for plumbing and water distribution.

Order aluminum extruded metal products for the construction and automotive industries


Extruded aluminum is extremely versatile. It's used to form aluminum cans, aluminum door and window frames, roofing, electric connectors, aerospace products, architectural framing, copier components, circuit board, modem housings and medical equipment.

I recommend: Almag customizes extruded aluminum parts, such as running boards, light reflectors, slat walls, trade show booths and sign systems. Follow the extrusion guidelines to get a quote. National Extrusion is a certified manufacturer and distributor of aluminum extruded shapes for a variety of industries including transportation, office equipment, medical equipment, building products, aerospace and electrical/electronics.

Purchase extrusion stainless steel channels for structural and other applications


The strength and non-corrosive properties of extruded stainless steel products make them the ideal choice on bridges, rail cars, rail construction, elevators, escalators and building structures.

I recommend: Stainless Structurals is a metal extruder that makes stainless steel beams, channels, equal and unequal angles, tees, cold drawn flats and half rounds. GSP, a division of ThyssenKrupp North America, offers extruded stainless steel channels for the building and rail road industries.

Tips & Tactics
Helpful advice for making the most of this Guide

  • Cold metal forming extrusion applications are much greener than hot extrusion applications because the metal oxidizes less and has closer tolerances, good surface finishes and fast extrusion speeds (if the material is subject to hot shortness).
  • Use steel metal extruding for applications under 50,000 lbs. If the application is larger than 50,000 lbs., it's more cost effective to roll the steel.
