The forging process uses high pressure and temperature to change the non-directional, or one-directional grain structure of the aluminum starting material, into the high integrity multi-directional grain structure of forgings. The aluminum remains solid throughout the process as the forging dies come together and changes the shape of the starting stock.
The resulting directional orientation of the grain structure places the highest material strength in the same direction as the highest operating loads. The result is “premium strength”. The world’s leading aircraft and aerospace manufacturers use one-piece forgings for precisely this reason: superior performance in critical structural applications.
All of the forgings produced by Performance Forge have the additional benefit, when requested, of a polished mirror finish. This can be achieved because of the high integrity of the metallic structure produced by the forging process.
