Aluminum 5083 Seamless Pipes/Tubes Manufacturer
Alu alloy grade 5083 is a typical alloy in AL-Mg series anti-rust aluminum, which is characterized by excellent welding properties and good.
Aluminum is a lightweight metal with good electrical conductivity, thermal conductivity, and plasticity. In the alloy 5083 , it serves to increase strength and hardness, while also enhancing the alloy’s corrosion resistance. Magnesium is also a lightweight metal, possessing good strength and rigidity, and it can improve the strength and hardness of the alloy. The combination of aluminum and magnesium endows 5083 material with excellent mechanical and corrosion – resistant properties.
5083 weldability
5083 alloy has good welding performance, can be welded by various welding methods, and the strength of the weld can be equal to the strength of the matrix in the annealed state. At the same time, it has good self-extension, cold formability, and reliable corrosion resistance, with the decrease of temperature, the tensile strength, yield strength and elongation of the base metal and welded joints are increased, and the low-temperature toughness is very good.
5083 Corrosion Resistance
5083 alloy has good corrosion resistance in various states, and has good corrosion resistance to atmosphere, fresh water, seawater, alcohol, gasoline and diesel, organic acids, concentrated nitric acid, and various foods..
ASTM B241 – Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Tube
ASTM B241 is the American standard that specifies requirements for seamless aluminum and aluminum-alloy pipes and tubes, including 5083 aluminum pipes. It covers dimensions, mechanical properties, chemical composition, and manufacturing processes for various aluminum grades used in structural and pressure applications.
5083 Aluminum Pipes Chemical composition
The 5083 aluminum alloy is commonly available in both O (annealed) and H112 temper, each providing different mechanical properties suitable for various applications.
5083 Temper
The O temper indicates that the material has been annealed
The H112 temper is achieved by strain hardening after a mild heat treatment. The H112 condition provides improved strength compared to the O temper
