7075 T651 Seamless Aluminum Tube Introduction
7075 aluminum alloy is a commonly used alloy with a wide variety. It contains zinc and magnesium. The most common aluminum alloy is the 7075 alloy, but it can't be welded, and its corrosion resistance is quite poor. Many CNC cutting parts are made of 7075 alloy. Zinc is the main alloying element in this series, and a small amount of magnesium alloy allows the material to be heat treated to very high strength properties. This series of materials is generally added with a small amount of copper, chromium and other alloys, of which the number 7075 aluminum alloy is especially top grade, the highest strength, suitable for aircraft frames and high-strength accessories.

Analysis of mechanical properties of
7075 T651 seamless aluminum tube
(1) The elemental properties of the combination are expressed as the highest percentage unless a range or minimum value is listed.
(2) In order to determine the appropriate numerical limits, the observed observations or calculated values are based on standard rules (ANSI Z25.1).
To indicate a clear scope.
(3) In addition to non-alloys, the amount specified for the elements in the alloy is usually indicated in the analysis report. But if in the process of analysis
It is suspected that other elements are present or some elements are suspected of being excessive, and further analysis should be carried out until confirmed.
(4) The content of aluminum in non-alloyed aluminum that is not through the refining process is the difference between the total amount of other metals and 100% pure aluminum - the difference
It is 0.01 or a little more. (the second place after the decimal point)
(5) It can contain up to 0.25% zirconium and titanium.
7075 T651 seamless aluminum tube production process
Zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than the 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 flaking corrosion will decrease. Subject to heat treatment, very high strength properties can be achieved.
7075 T651 seamless aluminum tubes are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is especially top grade. It is regarded as the best product of aluminum alloy, with high strength and far better than any mild steel. This alloy has good mechanical and anodic reaction. Representative applications include aerospace, mold processing, mechanical equipment, fixtures, and especially for the manufacture of aircraft structures and other high-stress structures that require high strength and corrosion resistance.
