Workpiece Materials and Power Requirements
Softer materials are much easier to deform and therefore require less force to draw. The following is a table demonstrating the draw force to percent reduction of commonly used materials.
| Material | Percent reduction | |||
|---|---|---|---|---|
| 39% | 43% | 47% | 50% | |
| Aluminium | 88 | 101 | 113 | 126 |
| Brass | 117 | 134 | 151 | 168 |
| Cold-rolled steel | 127 | 145 | 163 | 181 |
| Stainless steel | 166 | 190 | 214 | 238 |

Famous quotes containing the words materials and/or power:
“If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work”
—C. John Sommerville (20th century)
“The power of hope upon human exertion, and happiness, is wonderful.”
—Abraham Lincoln (1809–1865)
