An alloy of aluminium and manganese with a moderate strength, good formability, and weldability is called aluminium 3004. It is employed in numerous sectors and has a wide range of uses. Everything you need to know about this alloy, including its composition, mechanical properties, physical properties, applications, corrosion resistance, heat resistance, heat treatment, and machining, will be covered in this article. Find out why one of the most often used aluminium alloys is aluminium 3004 by reading on.
3004 Aluminium Alloy Composition
Aluminum (99% minimum) and manganese (0.8%) make up the bulk of UNS A93004. Additionally, it has trace amounts of silicon (0.6%), chromium (0.05%), iron (0.7%), copper (0.2%), and other elements that assist to enhance its workability and mechanical characteristics.
3004 Aluminium Mechanical Properties
Tensile strength of UNS A93004 is 275 MPa, while yield strength is 170 MPa. 10% of its elongation at break. Its Brinell hardness is 70HBW or less, and depending on the thickness of the material being tested, its fatigue strength ranges from 60 to 100 MPa. Depending of the temperature and pressure levels, its thermal conductivity varies between 140 and 175 W/mK and its shear modulus between 25 and 30 GPa.
3004 Aluminium Physical Properties
Aluminum 3004 is light and strong enough for industrial usage, with a density of 2.71 g/cm3. It is suitable for high-temperature applications including valves, flanges, and engine parts that are exposed to extremely high temperatures while they are operating because of its melting point of 645°C and boiling point of 2450°C.
3004 Aluminium Uses
Aluminum 3004 has a wide range of uses in a variety of industries, including construction, automotive manufacture, aerospace engineering, and the electronics industry, among others, because of its low cost and outstanding formability. Due to its great ductility, which enables it to be shaped into complex shapes without difficulty or loss in quality or performance qualities over time, it can be utilised to make machine components like gears. It is suitable for outdoor applications where exposure to moisture cannot be completely avoided, such as balconies or patios located near salty water bodies like oceans or seas, where it offers good corrosion resistance even when exposed to air containing salt vapours or moisture. It can also be used to make window frames.
Aluminum 3004 is the perfect material for structures near saline water bodies like oceans, seas, etc. since it exhibits high corrosion resistance even when exposed to air containing salt vapours or moisture. Due to its high ductility, which enables complex shapes to be formed without difficulty or quality degradation over time, as well as its strong welding capabilities, it is an excellent choice for a variety of structural components that require corrosion protection but still need to maintain their shape over time, such as window frames, among others.
Due to its excellent heat resistance property and melting point of 645 °C, aluminium 3004 can be used in environments with extreme temperatures up to 2450 °C without experiencing any deterioration in performance characteristics over time. This makes it ideal for valve components that are frequently exposed to extremely hot temperatures during their operation period, etc.
