Aluminum is a very light metal. During the 44 years from 1944 to 1988, the world’s aluminum production has increased by 19 times. The development of aluminum is so fast that aluminum itself has many
If industrial aluminum profiles do not undergo external action after the end of the extrusion process, then the non-uniformity of the deformation state is the basic cause of residual stress. Due to th
Aluminum profiles are characterized in that the properties and temperature of each part of the metal are relatively uniform and the friction is small. The characteristics of the metal flow are represe
The deformation of the metal in the barrel is extremely uneven, and there are two hard-to-deform areas: a corner at the junction of the barrel and the mold, called the front-end deformation area, usua
