Aluminium Pipes
Aluminum pipes are often used for a wide range of applications depending on the tempers and series they belong to. These modifications in the alloy bring changes in their resistivity, durability, aging, formability, and machinability.They are flexible lightweight and available at reasonable prices. Their lightweight property helps in providing greater volume/per weight. Aluminum pipes are heat-conducting and fit well in the applications of temperature control like refrigerators, air conditioners, etc. Their tarnishing capabilities are negligible and hence the paint or other coatings are long-lasting. Some aluminum alloys have excellent formability and can be formed into the most complicated designs and hence used in applications accordingly. The aluminum alloy which has silicon as the alloying metal is an example of such alloys whereas certain aluminum alloys are used in applications that require higher strength. Aluminum alloy HE-19 piper is a good example for this case since it may have low durability or formability but it is highly used in the aerospace industry for its high-strength features. Whereas Aluminum alloy 6063 pipes have a very smooth and shiny surface finish but cannot compete with the other alloys in terms of strength. They are widely popular for those applications that require the manufacturing of aesthetic products rather than strong products. It is lightweight and durable properties also increase its uses in the applications of hydraulic systems, fuel lines, racks, etc.
