Deep Drawn Aluminum Sheet

For those manufacturing operations that revolve around the deep drawing of steel the sheer mention of aluminum brings out a grimace.

Deep drawn aluminum sheet.

It is universally known for its inability to stretch its abrasive nature and its tendency to wrinkle. Although these statements may be partially true aluminum does have several advantages. Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. A variety of metals can be deep drawn including aluminum stainless steel aluminized steel cold rolled steel brass bronze cupro nickel nickel and titanium.

Deep drawing can achieve up to 43 reduction on a metal blank and multiple successive deep draws can be used to achieve part size or shape requirements. Deep drawing the process of turning sheet metal into hollow parts is a critical production process and from the measurement of certain material properties it can be seen that aluminum has favorable performance when compared to steels. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. Two main factors will cause the punch in deep drawing to draw the metal into the.

Deep drawing is a sheet metal forming process that involves complex material flow and force distributions. As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.
