Drawing of Aluminum Alloys, Wire.

The stresses occurring in the manufacture of aluminum wire may be calculated without correction coefficients both for low and also for high speeds of drawing, and the calculated values agree satisfactorily with those determined experimentally. For all sizes of wire, any increase in the reduction in area, in the coefficient of friction, and in the speed of drawing causes greater stresses. For every combination of area reduction, frictional coefficient, and drawing speed there are optimal die angles which minimize the necessary drawing force.
