On wrought aluminum alloys

Designation: Sn-Bi

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose: Tin coating on aluminum is used to enhance corrosion resistance, improved solderability, elimination of contact of aluminum with copper conductors, creation of an easily break-in layer on rubbing surfaces. Without a technological copper or chemical-nickel sublayer, tin plating of aluminum is impossible. The thickness of the sublayers is usually minimal and such sublayers are not indicated on the drawing (unlike multilayer tinning).

Adding bismuth to the coating allows you to: maintain solderability for up to 1 year, slow down the transition of the plastic white modification of tin to powder gray, and level out needle formation.

Purpose:  Multilayer tin coating on aluminum is used to ensure maximum corrosion resistance, improve solderability, protecting electrical contacts from oxidation and direct contact with copper, creating an easily break-in layer on rubbing surfaces.

Adding bismuth to the coating allows you to: maintain solderability for up to 1 year, increase frost resistance - slow down the transition of the plastic white modification of tin to gray powder at temperatures below -30°C, to prevent needle formation during storage.

Purpose:  Tin-lead coating on aluminum is used as a coating for soldering, as well as anti-friction and protective. In terms of corrosion resistance, it is inferior to the tin-bismuth alloy, but surpasses it in ductility. Tin-lead coating, like tin-bismuth, does not produce needles during storage and is stable at low temperatures, unlike pure tin. The appearance is gray, matte or semi-shiny.
