Aluminum alloy is another commonly used alloy with many varieties. It contains zinc and magnesium. Among the more common aluminum alloys, the alloy is the strongest, but it cannot be welded, and its corrosion resistance is quite poor. Many machined parts are made of alloys. Zinc is the main alloying element in this series, and the addition of a small amount of magnesium alloy allows the material to be heat treated to achieve very high strength properties. This series of materials generally add a small amount of copper, chromium and other alloys, among which numbered aluminum alloys are particularly top-grade and have the highest strength, suitable for aircraft frames and high-strength accessories.
-The composition of this series of alloys mainly includes aluminum, copper, magnesium, zinc and other metals. The ratios are shown in the following table:

Note:
Elemental properties of combinations are expressed as the highest percentage, unless listed as a range or is the lowest value.
In order to determine appropriate numerical limits, the observed or calculated values from the analysis are based on standard rules (.)
to indicate a clear range.
Except for non-alloys, the specified amounts of elements in alloys are usually indicated in the analysis report. However, if during the analysis process
it is suspected that other elements are present or some elements are suspected to be in excess, further analysis should be conducted until confirmed.
The aluminum content in unalloyed aluminum that has not gone through the refining process is the difference between the total amount of other metals and 100% pure aluminum - the difference
is 100% or a little more. (Second decimal place of percentage)
Can contain up to zirconium and titanium.
Zinc is the main alloying element in aluminum. Adding magnesium to an alloy containing 3 zinc can form a significant strengthening effect, making the heat treatment effect of the alloy far better than that of aluminum-zinc binary alloy. Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and spalling corrosion will decrease. After heat treatment, it can achieve very high strength properties.
-Aluminum Plate
-Aluminum Plate is known as the best product among aluminum alloys. It means that this alloy has been heat treated and pre-stretched, and the alloy has a tensile strength of 100% and a yield strength of 3. At the same time, the alloy has good mechanical properties and anodizing properties. The American Standards Union evaluates the alloy as Class B mechanical properties due to Can produce curled or easily broken chips, and has excellent surface treatment. - Mechanical properties Thermal expansion coefficient (-℃)/., Melting point range (℃):, Conductivity ℃ () ():, Resistivity ℃ ()㎡ /:.
