1. The alloy
element content is different. 6061 is more alloying than 6063.
2. Alloy elements
are different. The main alloy elements of 6063 aluminum alloys are magnesium
and silicon. With excellent processing performance, excellent weldability,
extrusion and plating, good corrosion resistance, toughness. Easy to polish,
the upper coating, anode oxidation effect is good, is a typical extruded alloy.
The main alloy ingesting elements of the 6061 aluminum alloy are magnesium and
silicon, and the Mg2Si phase is formed
3. Performance is
different. 6061 requires a certain strength, weldability, high corrosion
resistance of industrial structures. 6061 Requires a variety of industrial
structures of strength, weldability and corrosion resistance, such as pipes,
bars, shapes, sheets for construction trucks, tower buildings, ships, trams,
furniture, mechanical parts, precision machining, etc.
4. The oxidation
performance is different. 6061 oxidation performance in general, 6063 oxidation
performance is better
5. Plasticity is
different. 6061 plastic ity is general, and 6063 plasticity is better
6. Different range
of use
6061 is a
high-quality aluminum alloy material, with high toughness, good welding and
corrosion resistance, can be used in heavy vehicles, ships, aerospace
equipment, trucks, trams, molds, electronics, furniture, corrosion resistance
structure;
6063 is a very
strong integrated performance of aluminum alloy materials, with high strength,
wear resistance, corrosion resistance and high temperature resistance, can be
used in both building profiles and industrial profiles, often used in the
construction of aluminum alloy doors and windows, curtain walls, various
industrial frame structures, rail transportation, aerospace, military
equipment, automated conveying equipment and other fields
7. The heat
treatment process is different. Heat treatment refers to the strengthening of
heat treatment to eliminate internal stress inside the material and increase
its strength. In general, pure aluminum alloy, aluminum manganese alloy and
aluminum magnesium alloy can not be improved by heat treatment phase, and
aluminum copper alloy, aluminum magnesium silicon alloy and other carbides can
be used to achieve enhanced effect through heat treatment phase. 6061 after
solid melt treatment no longer cold processing, can be natural aging (T4
state), or directly artificial aging, that is, T6 state, its deformation coefficient
is larger, high hardness, not easy to control; Mechanics are stronger, but 6063
also uses T6 treatment method, its deformation coefficient will also be larger,
higher hardness, more prone to fracture than T5.
