Tin and tin-alloy processes

Acid tin SG-SN 40

The acidic bright tin process SG-SN 40 deposits bright and corrosion-resistant tin layers. It is suitable for various base metals such as copper , copper alloys, steel and steel alloys. SG-SN 40 can be used for rack and barrel applications.

Acid tin SG-SN 50

The acidic bright tin process SG-SN 50 is the further development of our SN 40 process and generates bright shiny deposits and corrosion-resistant coatings. It is suitable for various base metals such as copper, copper alloys, steel and steel alloys. SG-SN 50 is used for rack and barrel applications. The process can be operated with only one additive depending on the application. For more complex requirements 3 components are used.

Acid mat tin SG-SN 50

The acidic mat tin SG-SN 50 is an acidic tin process that generates mat and corrosion-resistant tin layers. It is used for many base metals such as copper, copper alloys, steel, and steel alloys. SG-SN 50 method is suitable for rack and barrel plating.

Tin-nickel SG-Sn-Ni

SG-SN-Ni is a tin-nickel process used to generate bright preserving tin-nickel alloy coatings. The coatings have a slightly reddish colour and the formation over a current density range of 0.005 A - 2A/dm2 without staining. The coatings always contain the same alloy content of 65% tin and 35% nickel. With SG-Sn-Ni achieves an excellent brightness depth spread. Even the most geometrically difficult shapes get a completely uniform metal distribution. Since the precipitate always the same alloy content and colour is generated. The Sn-Ni layers have a very high corrosion resistance, which is higher than that of a chromium precipitate. By adding our additive SG-Anthracite, it is also possible to deposit anthracite-coloured coatings.
