Forged

The brass and copper hot forgings are quality parts, comparing favorably in material integrity, dimensional tolerance and surface finishing with products made using other major 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

  • High Strength : In making a forging, the metal is worked twice under tremendous pressures: first during rod extrusion and then during forging. The double working under pressure compacts the metal and produces a very dense and refined grain or fiber structure. The tensile strength of the parts is thereby increased, and resistance to impact and abrasion is enhanced.

  • Leak Resistance : The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks due to flaws and voids. Often the thinner forged parts result in lighter weight and lower part cost compared to other forming processes.

  • Close Tolerances: A forging produced in a steel die with close tolerances offers several advantages. Overall part dimensions are held closer than in sand casting. Dimensions show minimum variation from part to part and permit automatic chucking and handling in subsequent operations. The precise designs on the die surface can produce sharp impressions on the forging surface, which is not economical with other forming processes.

  • Low Overall Cost: Mass production of brass forged parts lends itself to maximum savings. However, smaller quantities of copper alloy forgings can also prove economical when specific design problems must be overcome. These problems include leak integrity, close tolerances, high strength with low weight, and non-symmetrical shape.

DIS-ADVANTAGES

  • Cost: Forging can be more expensive than casting, especially for smaller production runs. This is because the forging process requires specialized equipment and skilled labor, and it can also be more time-consuming.

  • Weight: Forging can produce parts that are heavier than cast parts of the same material, which can be a disadvantage in some applications, such as aerospace and automotive parts.
