The 61147 lead free white bronze plating (barrel) process will give you silver and bright white bronze alloy deposits, with features as follows: Soft deposits and good level-up, excellent covering ability, high hardness and good corrosion proof ability; Bath can be used for continuous plating until 10 micron thick deposits. It can be directly used on the copper and its alloy, and also as primer deposits for other plating. This process is an epoch-making environment-friendly process, no heavy metal lead in any additives. The deposit is silver white color, suitable for primer deposits for electrophoretic paint. Deposits temperature resistant up to 120°C, and good soldering ability; Immerse plating in a layer of 1% 61147 golden and silver protection water, the surface will be more smooth and soft, in addition to improve its discoloring ability, so as to be good for assembly and machining. Coating meet EU strict regulation. 9. This plating technology, Han Lin may have declared national patent, please use it correctly.
