5251 aluminium tubes offer outstanding corrosion resistance, especially in marine atmospheres.

5251 tube offers high corrosion resistance and is ideal for marine applications.


5251 aluminium drawn tubes offer outstanding corrosion resistance, especially in marine atmospheres. The material is a medium strength alloy, which is readily weldable and finds use in various commercial applications. The quarter hard temper allows this alloy to undergo limited bending and forming operations. 5251 benefits from good ductility and formability. Excellent thermal conductivity and low density are also a feature which is common in the majority of commercial aluminiums.Though common in the marine sector, 5251 also finds use in applications, including architectural and general metalworking.


Stock Availability

We have available 5251 aluminium tubes in a wide range of sizes and tempers, including H12 and O.
