6013 Alloy Uses

Aluminium 6013 is an alloy commonly used in manufacturing aircraft components due to its superior strength and corrosion resistance. It is also used in automotive parts such as engine blocks and cylinder heads because it can withstand high temperatures without becoming brittle or cracking. Additionally, aluminum 6013 has been used for many years in architectural applications due to its malleability and strength. From window frames to handrails to bridge components, this durable alloy can be formed into any shape needed for construction projects.

Corrosion Resistance

aluminum 6013 has excellent corrosion resistance due to its low carbon content and high chromium content. This combination means that it does not corrode easily when exposed to moisture or other corrosive elements such as saltwater or chemicals. Its superior corrosion resistance makes it an ideal choice for applications where exposure to the elements could cause damage or wear over time.

Heat Resistance

Aluminium 6013’s heat-resistant properties make it well-suited for applications where there may be a need for high temperatures or prolonged exposure to extreme temperatures. This alloy has a melting point of up to 772°F (413°C), which enables it to withstand higher heat than other alloys without weakening or becoming brittle over time. This makes aluminium 6013 an ideal material for use in aircraft engines and other parts requiring frequent exposure to elevated temperatures while maintaining their structural integrity.

Heat Treatment

This alloy can be heat treated using several different methods depending on the desired outcome. The most common method is annealing which helps reduce stress levels present within the metal after extensive machining processes have taken place. Quenching can also be used, which involves heating the metal until it reaches a certain temperature before rapidly cooling it down to harden the material further while maintaining its ductility at lower temperatures. Heat treating aluminum 6013 should always be done by experienced professionals familiar with this particular alloy’s characteristics and properties to ensure optimal results are achieved every time.


Machining aluminium6013 requires special tools designed specifically for this type of material in order to achieve the best results from cutting operations without damaging or compromising the material’s surface quality or structural integrity during machining processes. High-speed steel (HSS) tools work best when cutting aluminium6013 because they offer superior edge retention compared with carbide tools which tend to wear out faster when working with this particular material. Additionally, cobalt-based tools are great for precision cuts as they offer greater control over cutting operations than HSS tools can provide. When machining aluminium601 3, care must be taken not to put too much pressure on the tool as this could lead to premature tool wear or even breakage if excessive pressure is applied.


Welding aluminium6 013 requires special attention since welding this particular alloy often leads to porosity issues caused by hydrogen entrapment during welding operations. In order to prevent these issues, welders must use a low amperage setting when welding aluminum alloys such as 6013 since excess current leads to increased porosity levels within welds. Additionally, preheating the base material before welding is recommended since doing so helps reduce hydrogen levels within welded materials by allowing trapped gasses to escape prior to initiating welding operations.


In short, aluminium60 13 is a versatile alloy that offers superior corrosion resistance, heat resistance, and machinability making it suitable for a variety of applications ranging from automotive parts to architectural components. Its ability to be heat treated provides additional options when selecting materials for specific projects, while its good weldability makes it easier to join pieces together without compromising structural integrity during fabrication processes. With proper care and attention given to each step involved in fabricating parts with 6013, you can expect excellent results every time! Therefore, if you’re looking for an all-around metal suitable for your next project – look no further than aluminium60 13!
