Production technology of aluminum alloy sections used for brake pad

The invention discloses a production technology of aluminum alloy sections used for a brake pad, and belongs to the technical field of metal mechanical machining. The machining of vehicle bumper aluminum alloy sections is finished through the following processes of: preparing materials, smelting, stirring with a permanent magnet, sampling, adjusting ingredients and temperature, turning down, refining (primary purification), standing, adding Al-Ti-B silk in an on-line manner, performing on-line degassing and deslagging (secondary purification), performing two-stage filtering, performing hot top casting at the same level, homogenizing an ingot, mechanically machining the ingot, heating the ingot with an induction furnace, extruding, performing on-line quenching, stretching and straightening, aging, detecting the structure and performance of the sections and carrying out delivery. The aluminum alloy sections machined by the invention is good in abrasion resistance and corrosion resistance, stale in dimension, resistant to high temperature, high in strength, good in fatigue resistance performance and long in service life.
