natural oxidation The oxide film is thin, with a thickness of about 0.5 to 4 microns, and is porous, soft, and has good adsorption properties. It can be used as the bottom layer of organic coatings, but its wear resistance and corrosion resistance are not as good as anodic oxide films; electrochemical oxidation The thickness of the oxide film is about 5 to 20 microns (the thickness of the hard anod...

7075 aluminium alloy is a very high strength aerospace aluminium and is commonly used in applications where the strength of the material is critical and where the need for good corrosion resistance is not important. Offering superior stress corrosion resistance, 7075 provides very high yield and tensile strengths which is dictated by the particular chosen temper. Alloy 7075 is an Al-Zn-Mg-Cu based ...

Alloy 7001 is an Al-Zn-Mg-Cu based superhard aluminum alloy that can be strengthened by heat treatment. The tensile strength of 7001 alloy aluminum tube in T6 state can reach more than 600MPa, and the yield strength is more than 550MPa, and its strength and stiffness are higher than those of the same series of 7A04 and 7075 alloys....

The struts are strong and resilient: the best rods at the moment are carbon rods, followed by aluminum alloys, then fiberglass, and finally irons (except for troops, which are pretty much useless). Aluminum alloy rods are divided into aviation aluminum alloys, 7075T9 and 7001T6 in terms of price and performance. A reasonable combination of strut sizes is obtained: 4 rods of 50mm, 3 rods of 40mm, an...

Aluminum climbing pole is a portable outdoor exercise tool, and the interior is hollow, so it has enough strength while having low weight. The properties of common materials for trekking poles are obtained by consulting the information, as shown below. Aluminum alloy: density is 2.7g/cm3, with good strength and hardness; tungsten steel: density is 12g/cm3, with high wear resistance; titanium alloy:...
