TU 1811-005-75479902-2006 Strips of aluminum alloy, grade АА3003, clad with “silumin”alloy. Technical requirements

Description

Strip is made of aluminum alloy, grade АА3003 clad with on one-side (APS1) or double-side (APS2) coating “silumin”-type alloy.  

Composition

aluminum-silumin-en

  • Base – aluminum alloy АА3003 with chemical composition acc. to GOST 4784.
  • Coating – silumin with the following chemical composition:      
    9,0 – 10,5% Si      
    ≤0,8% Fe      
    ≤0,25% Cu      
    ≤0,1% Mn      
    1,0 – 2,0% Mg      
    ≤0,2% Zn      
    0,02 – 0,2% Bi      
    The amount of other elements – no more than 0,15%.

The thickness of cladding layer h varies from 8 to 14% of nominal thickness of the finished strip.
