Tin - Zinc
Our latest development in alloy plating solutions is one that plates 70% tin and 30% zinc. Our tin zinc alloy plating solution is an environmentally friendly alternative to cadmium plating. It is two to three times more effective than cadmium and up to ten times better than zinc. The picture opposite illustrates the effectiveness of the process. Tin/zinc can also serve as a base coat for gold when plating on to steel and iron parts. Tin/zinc plates dull, but can easily be polished to high lustre with MetaPrep, MetaPrep Ultra or the Hand Polishing Kit.
Tin/zinc has the following main advantages:
- An excellent alternative to highly toxic cadmium.
- Very good corrosion resistance
- Excellent solderability
- Very ductile
- Plates a uniform thickness, even in recesses.
|Compositions of 70% tin, 30% zinc – environmentally friendly alternative to cadmium||A base coat for gold when plating on to steel and iron|
|2-3 times more effective than cadmium and 10 times better than zinc||Coating steel to dramatically slow down corrosion, particularly in salt water|
|Can be easily soldered||plating when further construction work is necessary|
|Plates to a uniform thickness, even in recesses||Plating jobs where plating to specific thicknesses is an important consideration|
|Very ductile||Plating items that will need to have some flexibility|
