Hot Forging for Copper, Brass & Bronze Alloys

What is Hot Forging?

Hot forging is the forging process definied according to the temperature of billets for forging. In hot forging, the material is able to retain its deformed shape as it cools because metals are plastically deformed above their recrystallization temperature.

The desired final shape achieve by hot forging is accomplished using hydraulic or pneumatic hammers, presses, and other similar machinery, which compress the heated metal in the die. The dies used in hot forging have to be custom-made according to the design from customers. After heating, the billet is more pliable, so hot forging allows for more intricate shapes than cold forging, making a vast array of part geometries possible. But the dimensional tolerances of hot forgings are generally not as tight as in cold forgings.

Hot forging process begins with a forged metal ingot. The metal is heated until it reaches its plastic deformation temperature, which may up to 1200°C depending on the metal, and such high temperature must be maintained throughout the hot forging process. As the material is formed and shaped, its grain structure is broken down and homogenized into finer grains, which increases the yield strength, ductility, and toughness of the material.

After the hot forging process, the hot forged blanks must be cooled under room temperature for a while. Care must be taken in the cooling process, if cooling too quickly, hot forgings can result in warping. Compared to casting process, the hot forging process produces little to no material scrap, making it one of the most efficient metal forming process.


Hot Forging for Copper, Brass & Bronze Alloys

hot forging for copper, bronze & bronze alloys

Hot forging is not only limited to steel and aluminum parts, it can be used to produce copper, brass & bronze alloys as well. The copper, brass or bronze hot forgings are quality parts, comparing favorably in material integrity, dimensional tolerance and surface finishing with products made using other metalworking processes. As a result of deformation, hot brass forging grants superior density and freedom from flaws. Forming under heat and pressure in precise closed dies produces dimensional accuracy, always repeatable part to part and lot to lot. Excellent surface finishing with a clean lustrous appearance is readily available with copper and brass forgings.

Advantages of Brass, Copper & Bronze forgings

Copper, brass & bronze forgings offer the engineers unique advantages that other metals cannot match. Different copper alloys can be selected to exploit the following unique characteristics:

  • Good Strength
  • High electrical and thermal conductivity
  • Superior corrosion resistance
  • High ductility
  • Outstanding machinability
  • Excellent joining and plating characteristics
  • Superior polishing and finishing characteristics
  • Non-magnetic properties
  • Non-sparking characteristics
