Aluminium 7072 is highly resistant to various types of corrosion, including intergranular corrosion and stress-corrosion cracking. It is also resistant to crevice corrosion when exposed to acidic or alkaline environments. These properties make aluminium 7072 an ideal choice for applications that require materials which are resistant to rusting or exposure to harsh chemicals.
Aluminium 7072 is able to withstand extreme temperatures without losing its mechanical properties or becoming brittle. This makes it suitable for applications such as exhaust systems, turbochargers, and engine components, as it can withstand intense heat without becoming damaged or deforming over time. In addition, aluminium 7072 has superior heat dissipation qualities, which make it perfect for heat-sensitive components like brakes or clutches.
Aluminium 7072 can be hardened by undergoing the process of heat treatment. During this process, the material is heated up to approximately 500°C before being cooled down again in oil or water, depending on what type of hardness is required. After the cooling process is complete, the material should have improved wear resistance and better machinability than before treatment.
aluminium 7072 can be machined easily using standard tools due to its softness and malleability, although care must be taken when working with this material as it tends to form burrs during machining, which can damage parts if not removed properly. When machining aluminium 7072, it's important to use plenty of lubrication between the tool and material to reduce friction and improve cutting performance while also ensuring that the temperature remains below 250°C during operation to avoid any potential damage caused by overheating.
7072 Alloy Uses
Aluminium 7072 is an alloy that is particularly well-known for its durability and strength while still having the lightweight form of other aluminum alloys. It is used in a vast array of applications, ranging from making sports equipment like baseball bats and golf clubs to being employed in automotive parts such as wheel rims and suspension components. Its toughness makes it an ideal choice for providing structural support due to its power to handle corrosion environments better than many other steel alloys. Aluminium 7072 is also resistant to climate change, a significant advantage for industrial applications which require reliable performance over many years. This level of robustness has made this alloy perfect for use offshore platforms or in any area where wear and tear must be kept to a minimum.
