Metal cladding aluminum strip 4343/3003/4343 H14Signi'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.
