Description

This range of bulk metal materials for surface treatment covers pure tin, tin alloys and zinc in several supply forms: anodes, ingots, plates and wire. It includes the Sn99.9-Anode, the zinc anode Zn99.995 Optiloop (article number 950051) and the WM89 SnSb7.5Cu3.5 thermal spray wire (article number 950007). Each grade is identified by its alloy designation and, where assigned, its article number for unambiguous ordering.

The pure tin and tin alloy materials are intended mainly for tin plating. Billets and plates have proven particularly suitable as anodes for tinning small parts by barrel plating. The bulk materials also work well as anodes in titanium baskets, which allows the anode charge to be replenished in loose form. The standard alloys in this group are Sn 99.9 and SnPb. Other special alloys and formats can be supplied on request.

For loading anode baskets, the tin materials come in three standard shapes. The sphere ingot has a diameter of 50 mm, the hemisphere ingot measures 25 x 50 mm and the pellet measures 12 x 25 mm. These formats let users choose the piece size that best suits their basket design and plating setup.

The Zn99.995 Optiloop extends the range to zinc anode material with a purity designation of 99.995. The WM89 SnSb7.5Cu3.5 is a tin-based alloy containing 7.5 % antimony and 3.5 % copper, supplied as wire for thermal spraying.

Product data sheets and safety data sheets are available for the anode materials Sn99.9 and SnPb. Further technical documentation can be provided on request.
