← Return to Aluminum product list
2S is pure aluminum with an aluminum purity of 99.0% or higher.
1100 and 1200 indicate that they are aluminum with a purity of 99.0% or higher, respectively.
It has excellent corrosion resistance, workability, weldability, and electrical/thermal conductivity. However, its disadvantage is its low strength.
As the purity increases, strength decreases, and the gloss after processing tends to increase as well.
A typical source of 2S is the fin part of the radiator used in air conditioners.
It is also used for kitchen equipment.
The 2S collected is visually checked using an analyzer to see if it is mixed with other alloys, then it is put into a flexible container, pressed, and shipped to the manufacturer.
