Product Description

7A04 the most commonly used superhard aluminum, high strength alloy, can be heat treatment enhanced. It is usually used in the quenching artificial aging condition, and the strength is much higher than the general hard aluminum, but the plasticity is low.

There is a good corrosion resistance and stress concentration tendency in the semi-finished products and aluminum plates with less thick sections. It has good welding quality and bad gas welding, and the machinability is low after heat treatment and annealing.

7A04 aluminum rolling Aluminum Rolling Heat treatment:

1.Uniform annealing: heating 450~465℃;Insulation 12~14h;Furnace cooling.

2.Complete annealing: heating 390~430℃;Insulation 30~120min;The furnace is cold to 150℃ air cooling.

3.Quenching and aging: quenching 465~480℃, water cooling ;Artificial aging (aluminum foil) 115~125℃24h, (uncoated aluminum profile) 135~145℃16h, (half products), 115~125℃3h heating, level 2, 155~165℃3h air cooling.

Status: aluminum alloy hot extrusion seamless tube (H112, T6), aluminum alloy sheet (H112, T6 state)
