On copper and its alloys

Designation: Sn-Bi

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose:  Tin coating on current-carrying copper busbars and flexible connections is used for their </undefined: p>protection from oxidation, stabilization of transition resistance, giving a highly decorative commercial appearance and eliminating direct contact of the copper busbar with aluminum or galvanized steel (undesirable galvanic couple). Tin-bismuth improves solderability (the solderability of the surface lasts for about a year) and creates easily break-in layers with movable electrical contacts. Adding bismuth to the coating slows down the transition of the plastic white modification of tin into powder gray at sub-zero temperatures below -30°C. Bismuth also suppresses the process of “needle formation,” which is important in electronics products.

Designation: Sn-Bi

Synonyms: Tinning.

Price:from 10 rub. per dm²

Purpose: Tin coating on copper busbars up to 3 meters is used to protect against corrosion, stabilize transient resistance, and prevent direct contact of the copper busbar with aluminum and galvanized steel (unwanted galvanic couple). Tin-bismuth improves solderability and creates easily break-in layers with movable electrical contacts. The coating improves the appearance of the products. Adding bismuth to the coating allows you to slow down the transition of the plastic white modification of tin to powder gray at temperatures below -30°C.

Purpose:  Tin coating on copper and brass it is used to protect against corrosion, improve appearance, improved solderability, protection of electrical contacts from oxidation and stabilization of contact resistancecreation on rubbing surfaces easily break-in layer.The addition of bismuth to the coating allows maintain solderability for up to 1 year,slow down the transition of the plastic white modification of tin to powder gray,slow down the needling.
