IWG’s innovative electrolyte as a genius palladium alternative – reduce costs, increase quality
The answer to rising palladium prices: Pallega® blend Sn Genius.
The new palladium-tin electrolyte from IWG Pallega® blend Sn Genius scores with the same positive properties as pure palladium – but at a much lower cost. With applications in all areas, whether for electronics, jewellery, eyewear or writing instruments, it is a true all-rounder. The innovative Pallega blend Sn genius offers a versatile solution for various industries.
Like pure palladium – but more genius!
ONE 4 ALL. One product for all applications
Decorative applications
The bath can be used to deposit alloys with a tin content of up to approx. 30 % in a bright, shiny finish. Pallega® blend Sn is cobalt- and nickel-free, making it ideal for the manufacture of jewellery, eyewear and writing instruments.
Technical applications
Even technically demanding components can be coated with Pallega® blend Sn. As a functional layer for demanding layer sequences, palladium-tin can take on the function of a barrier layer to minimize intermetallic diffusion and prevent corrosion of base layers or the base material.
The comparison is worth it
Common layering sequence for costume jewellery with Pallega® blend Sn compared to the more cost-intensive pure palladium.
This can be seen particularly clearly in a standard coating sequence. Replacing the more cost-intensive pure palladium intermediate layer with the new palladium-tin alloy saves around a third (!) of the costs.
Pallega® blend Sn also has no disadvantages compared to pure palladium (Pallega pure HT).
Nickelfree alternative for writing instruments
Pallega blend Sn is cobalt- and nickel-free and therefore ideal for writing instruments.
In order to be able to eliminate nickel in writing instruments, for example, the conventional palladium-nickel alloy can be replaced by the new palladium-tin alloy in the intermediate layer in a ratio of 80:20.
Cost savings even with genuine jewellery
In this example, the replacement of pure palladium with our new palladium-tin alloy also results in a cost saving of approx. 12.50 % for sterling silver genuine jewelry.
Tin as an alloying metal is inexpensive and is not subject to major price changes.
Electrolyte properties
The electrolyte Pallega® blend Sn is insensitive to cyanides and works in a pH range of approx. 7 – 8 and is suitable for both rack and barrel coating.

SO2 Corrosion test:
The comparison of the surface of palladium-tin alloys to pure palladium after SO2 corrosion testing shows a similar, only weak, attack. The corrosion resistance is therefore more than sufficient for most applications.

Corrosion test according to DIN EN ISO 22479:2022-08, Corrosion of metals and alloys – testing with sulfur dioxide in a humid atmosphere (fixed gas volume method) (ISO 22479:2019)
Abrasion test:
Our palladium-tin alloy has a higher abrasion resistance than electroplated pure palladium. Maximum abrasion resistance was found with an alloy of 75/25 Pd/Sn.
Test procedure: Taber Abraser 5135, load 250g, grinding paper grid 1000, 25 revolution/pass
Scanning electron microscopic analyses
Crack-free surface:
FIB sections with Xe+ plasma in layer structures with palladium-tin alloys show a grain boundary-free, crack-free homogeneous alloy.
