This weakens the aluminium and creates a fracture line.
Best grade of aluminum sheet for bending.
Series 1xxx are the aluminum alloys with 99 00 pure aluminum.
In the h14 temper 062 stock can take a dead sharp zero inside radius bend without cracking.
It can be fabricated by most of the commonly used techniques and it has good workability in the annealed condition.
But one thing that aluminum does not always offer is ease of workability in particular forming bending.
Its one of the most widely available aluminum alloys and is likely cheaper than 5052 as well.
Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
This is generalizing of course as there are ways to form 6061.
You get average strength very good.
They are very ductile in the annealed condition.
In most cases this is probably the best alloy for bending.
Series 2xxx are the aluminum copper alloys.
Beware of bad gouge bad intell.
Aluminum offers good corrosion resistance and is easily welded.
It also comes in many different shapes including flats rounds and structurals.

All that extruded aluminum at lowes and home depot.
The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6.
They have little structural value.
You get high elongation not as high as 3003 however and a solid.
With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
From hands on experience 6061 t6 will crack and 2024 t3 will break like a piece of glass.
This alloy comes right behind.
This grade has a great range of mechanical properties and corrosion resistance.
Ideally part designers should know that when it comes to aluminum grades 3003 and 5052 will bend 6061 will not.
The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx.
Place the fracture line over the edge of a table and bend the overhang slightly downwards.
For example if weldability is most important to your project but strength is not it may make sense to choose alloy 1100 as this aluminum grade has excellent weldability but is not typically used for high strength or high pressure applications.
Which aluminum alloy bends best.
The most versatile of the heat treatable aluminum alloys while keeping most of the good qualities of aluminum.
The top 3 aluminum alloys for being are the 3003 which has medium strength and the best cold workability the 5052 which is the highest strength alloy of the more common non heat treatable grades and the 6061 which is one of the more versatile heat treatable alloys.
These alloys have excellent machinability limited cold formability.
Aluminum 6061 t6 and 6063 t6 are the most common grades and tempers of aluminum specified.
