2. Spinning conditions and possibilities

2.1 General

A large number of factors govern the spinning conditions of aluminum alloys. These factors depend on the following four elements.

• The alloy itself:

  • ability to deform by extrusion ;

  • resistance to deformation ;

  • critical quenching speed (for press quenching) ;

  these factors being conditioned by the alloy's composition and its state of homogenization before spinning.

• Wiring installation:

  • press power and dimensions ;

  • die cooling systems ;...
