8014 Alloy Mechanical Properties


8014 Alloy Uses

Aluminium 8014 is used in industries that require strong yet lightweight materials; it is commonly used for structural components such as frames and beams. It is also used for aircraft parts due to its strength and lightweight. Other uses include piping, automotive components, and marine vessels due to their corrosion resistance.

Corrosion Resistance

One of the key properties of aluminum 8014 is its ability to resist corrosion. This makes it an ideal material for use in environments or industries with harsh conditions or extreme temperatures. Additionally, this property makes it suitable for use in applications where high levels of saltwater are present or frequent contact with other corrosive substances occurs.

Heat Resistance

Another important feature of aluminium 8014 is its heat resistance capability; it can withstand temperatures up to 350°C without any damage or degradation occurring to the metal’s structure or composition. This makes it suitable for use in high-temperature environments since it won’t be affected by the extreme heat present there.

Heat Treatment

The heat treatment process is essential when using aluminium alloys due to their tendency to become brittle when exposed to cold temperatures. Heat-treating aluminium 8014 helps make the metal more ductile, allowing it to better resist deformation from external forces such as bending or twisting without cracking or breaking. The heat-treating process also increases the metal’s strength and hardness, making it more durable than before.


Aluminium 8014 offers excellent machinability, which makes it easy to cut and shape into desired forms with precision accuracy if needed; this means that complex shapes can be easily achieved with relative ease compared to other metals, such as steel which require additional time and effort when cutting them into intricate shapes or designs by hand or through machine tools like lathes or milling machines.


Welder operators often choose aluminium alloys like aluminium 8014 because they offer superior weldability compared to other metals, such as steel, thanks to their low melting point, which allows them to be welded quickly without having any negative effects on their strength or durability after welding has finished being completed successfully.


In conclusion, aluminium 8014 has a wide range of uses due to its excellent properties such as corrosion resistance, heat resistance, machinability, and weldability; these features make it an ideal choice for many industries, including aerospace engineering, automotive components manufacturing, marine engineering projects requiring strong but lightweight materials etc., making it one of the most popular choices amongst engineers who need reliable materials that can stand up against harsh environmental conditions while still being light enough not compromise on performance levels required by modern engineering standards set forth today by major companies worldwide.
