Coat thic­k­ness and com­po­si­ti­on
ALTEF® is sui­ta­ble for coat thic­k­nes­ses ran­ging from 15 to 70 µm, depen­ding on the aluminium alloy used. The recom­men­ded coat thic­k­ness is 40 µm. Half of this lay­er thic­k­ness ‘grows’ into the base mate­ri­al, resul­ting in an appli­ca­ti­on of 20 µm.

Tole­rance ran­ge
‑For wrought pla­tes: ± 5 µm
‑For cast pla­tes: ± 7 µm
‑For cast and die-cast allo­ys: ± 10 µm
This infor­ma­ti­on applies to a coat thic­k­ness of 40 µm. Tole­rance ran­ge varies with lar­ger or thin­ner coats.

Intrin­sic colour
The colour of a com­po­nent coa­ted with ALTEF® depends on the alloy, the coat thic­k­ness and the type of pro­ces­sing. The colour spec­trum ran­ges from light grey to anthr­a­ci­te.

Dye­ing
ALTEF® can also be dyed black (accor­ding to VSA*210 / cor­re­sponds appro­xi­m­ate­ly to RAL9001). It is also pos­si­ble to pro­du­ce a gold-like colour (GOLD), but this is only available with spe­cial allo­ys.
