aluminum hinge extrusions

Warm Extrusion
Warm extrusion is done above room temperature, but below the recrystallization temperature of the material the temperatures ranges from 800 to 1800 ¡ÆF (424 to 975 ¡ÆC). It is usually used to achieve the proper balance of required forces, ductility and final extrusion properties
