The profile is composed of following components, by weight, 0.1-0.3 parts of copper, 0.4-0.8 parts of silicon, 0.6-0.8 parts of iron, 0.1-0.15 parts of manganese, 0.8-1.4 parts of magnesium, 0.2-0.25 parts of zinc, 0.03-0.35 parts of chromium, 0.1-0.15 parts of titanium and the balance aluminum. The preparation method includes following steps: firstly, according to a conventional casting and melting technology, mixing and heating the components to 720-760 DEG C for melting according to a formula proportion; carrying out a casting process after the components being melted to obtain an aluminium alloy casting blank casting blank; carrying out a conventional extruding process to the aluminium alloy casting blank casting blank to obtain an extruded profile; placing the extruded profile into a thermal treatment furnace within 48 hours; carrying out a thermal treatment process with a heating temperature being 350-410 DEG C and a thermal insulating time being 30-120 minutes; and finally carrying out an air-cooling process or a water-cooling process. The profile has advantages of a moderate strength, an excellent corrosion resistant performance, a good weldability and a good oxidation effect.
Description
Technical field
The present invention relates to a kind of preparation method of aluminium alloy element, be specifically related to a kind of bumper aluminium alloy extrusions and preparation method thereof.
Background technology
Some aluminium alloy element, for specific function purposes, usually proposes specific function requirement to the mechanical property of material and product.For example, for automobile rear bumper frame assembly aluminum alloy extrusion member, to absorb burst impact energy be inferior primary structure member of major function feature as a kind of, and its state product mechanical property span of control of supplying proposes following particular requirement: tensile strength Rm >=190Mpa; Non-proportional extension intensity Rpo.2=180 ± 20Mpa and elongation after fracture A5 >=12%.This requirement has specified that this extruded member need meet in the time standing very shock load, and material plastic yielding delayed fracture occurs rapidly to absorb its impact or Impact energy; Meanwhile also limit the physical metallurgy behavior of this alloy material in processing history.
Conventional alloy is because of its alloy element wide scope, and the strengthening phase quantity, form and the distribution that are caused by alloying element, and the reason such as thermal treatment history is all difficult to meet this particular requirement, more cannot form stable large-scale production ability.
