4343 aluminum coil strip for aluminium radiators
Cladding aluminum strip
Signi's well established, roll bonding process guarantees tight cladding thickness tolerances, which are essential for ensuring stable brazing results. Rather thin clad layers of 5% can be manufactured, as well as brazing materials also with a cladding thickness of 20%.
1> Tolerance according to EN and ASTM.
2> Higher thickness on request.
3> Special dimensions, tolerances, and alloys on request.
The state-of-art slitting line also allows Signi Aluminium to meet the demand for ever-closer width tolerances for tube stock materials. Depending on the material thickness width tolerances from max. 0.05mm up to max 0.20mm can be ensured.
