It s frequently fabricated into raceways decorative trim and other parts where strength and hardness are not required.
Annealed aluminium sheet.
In zone refined aluminum this reversion may take place at room temperature.
The soft annealed aluminium is beaten over various diameter pipes with a soft mallet.
Any involved forming can lead to cracking or fatiguing the material but annealing can reduce these problems.
Easy to form pure 1100 aluminum sheets and bars because 1100 aluminum is 99 pure it offers superior formability corrosion resistance and electrical conductivity.
The sheet work is now nearing completion and the zippo top is taking shape.
Both proper heat application and temperature measurement are important.
You can see that welding clamps were also used for tight short bends.
The main reason to anneal aluminum is to improve malleability.
The non heat treatable aluminum alloys may be torch annealed many times to achieve the necessary shape.
