Aluminium 6000 series

6000 series aluminium grades contain 0.2-1.8% silicon and 0.35-1.5% magnesium as the major alloying elements. These grades can be solution heat-treated to increase their yield strength. The precipitation of magnesium-silicide during ageing hardens the alloy. A high silicon content enhances precipitation hardening, which can result in reduced ductility. Still, this effect may be reversed by adding chromium and manganese, which depresses recrystallization during heat treatment. These grades are challenging to weld because of their sensitivity to solidification cracking, so proper welding techniques must be employed.

• Aluminum 6061 is the most versatile among the heat-treatable aluminium alloys. It has excellent formability (using bending, deep drawing, and stamping), good corrosion resistance, and can be welded using any method, including arc welding. The alloying elements of 6061 make it resistant to corrosion and stress cracking, and it is weldable and easily formable. Aluminum 6061 is used to produce all forms of aluminium structural shapes, including angles, beams, channels, I beams, T shapes, and radius and tapered corners, all of which are referred to as American Standard beams and channels.
• Aluminum 6063 has high tensile strength, good corrosion resistance, and excellent finishing qualities, and it is used for aluminium extrusion. It is suitable for anodizing because it can produce smooth surfaces after forming intricate shapes and has good weldability and average machinability. Aluminum 6063 is called architectural aluminium since it is widely used for railings, window and door frames, roofs, and balustrades.
• Aluminum 6262 is a free-machining alloy with excellent mechanical strength and corrosion resistance.
• 6351 is a heat-treatable high-strength alloy with excellent corrosion resistance and excellent weldability with a structural surface finish. The higher strength of 6351 is ideal for structural applications, particularly in marine, defence and transport. Aluminum 6351 is often used to make engine components, aircraft parts, and ships’ bodies due to its superior strength-to-weight ratio. It can also be used in construction projects such as bridges and buildings due to its excellent corrosion resistance properties. In addition, this alloy can be used for decorative purposes because of its attractive finish when polished.

 Corrosion Resistance Aluminum and more 6060 series

6060 alloy is one of the most common alloys of the 6000 series. It is a heat-treatable alloy with very good corrosion resistance and weldability. It is commonly used in window and door frames in residential and commercial applications. It is an ideal alloy for very complex cross-sections and has a very good anodising response.

 Corrosion Resistance Aluminum and more 6061 series

6061 is a heat-treatable alloy with mechanical properties equivalent to 6005A. It has good corrosion resistance, but like 6082, its extruded surface finish is not as good as 6060. It is a quench-sensitive alloy and therefore generally used for symmetrical shapes.

 Corrosion Resistance Aluminum and more 6106 series

6106 is a heat-treatable alloy with mechanical properties between 6060 and 6005. It has excellent corrosion resistance, and its good extrudability enables more complex shapes to be extruded than can be produced with 6061 or 6082.

 Corrosion Resistance Aluminum and more 6082 series

6082 has excellent corrosion resistance and the highest strength of the 6000 series structural alloys. As with all structural alloys, the extruded surface finish is not as good as alloys such as 6060 or 6063.
The higher strength of 6082 has seen it replace 6061 in many applications. 6082 has good weldability, and when DNV (Det Norske Veritas) is certified, it is commonly used in marine applications.

 Corrosion Resistance Aluminum and more 6351 series

6351 is a heat-treatable alloy very similar to 6082 with similar characteristics, including corrosion resistance and strength. Many European specifications now call up 6082 in lieu of 6351.

Aluminium 6351 has excellent corrosion resistance properties, which makes it ideal for use in marine environments or other areas where moisture or salt water can cause corrosion problems. The alloy has a protective oxide layer that prevents oxidation from occurring even after long exposure times. This makes it an ideal material for outdoor use in areas with high humidity or salty air.

Conclusion

La lega di alluminio 6106 è una lega per estrusione progettata per fornire una combinazione ottimale di proprietà meccaniche, complessità di forma, spessore minimo della sezione e buona finitura superficiale insieme alla buona resistenza, saldabilità e formabilità associate alle leghe della serie 6000. Sono possibili forme molto complesse che non sono ottenibili con leghe più forti come la 6182. (Le leghe della serie 6000 raggiungono le loro proprietà mediante trattamento termico che può essere regolato per fornire combinazioni di condizioni di resistenza e formabilità con buona resistenza alla corrosione e saldabilità. Poiché le proprietà sono ottenute mediante trattamento termico, la saldatura per fusione riduce le proprietà non saldate fino a 50 %.)
