Souriau: 20% of Cadmium Production Already Switched to RoHS Zinc Nickel Plating Line

Last year, Souriau manufactured more than 50% of its 38999 connectors with a RoHS plating, further reinforcing the company's position as industry green leader in the connector market. The company has more than a decade of experience with RoHS Zinc Nickel plating, which is now considered a superior RoHS-compliant alternative to cadmium by the MilAero industry.

Souriau has now industrialized this plating for most of the company's MilAero connector lines, which includes the D38999, Series I, II and III, MIL-C-26482 Series I, VG96918, micro38999, caps and backshell. Souriau is a leading manufacturer of RoHS Zinc Nickel plating for D38999 shells and in addition the company received a QPL certificate in 2009 for its excellence and ingenuity in the  production of RoHS Zinc Nickel connectors. The company's MilAero clients consider Souriau Black RoHS Zinc Nickel as the most credible industrial alternative to cadmium for the D38999 Series III.

RoHS Zinc Nickel is non-reflective and can be used at high temperatures (+175°C) or with specific fluids like de-icing. This unique combination allows the D38999 RoHS Zinc Nickel to be utilized in various applications. For the army, RoHS Zinc Nickel is widely employed because of its back compatibility with legacy cadmium parts.  It can be used for instance with ruggedized PCs, electrical engines, or weapon control boxes. For the MilAero application, the benefit of using RoHS Zinc Nickel plating is its universal acceptance with other various already installed finishes, such as passivated stainless steel, composite nickel, or alodine. RoHS Zinc Nickel's outstanding fluid resistance is an additional benefit when used together with actuator systems in unpressurized areas.  RoHS Zinc Nickel plating is made according to the well-known and accepted electrolytic deposit process, is RoHS compliant, and not listed as a "suggested human carcinogen". Another advantage of Souriau RoHS Zinc Nickel is that its rough surface makes it better adapted to accept heat shrink boots. RoHS Zinc Nickel is therefore the Souriau choice for the cadmium replacement over the next decades. All the MilAero RoHS Zinc Nickel range will be exhibited at "Le salon du Bourget" from the 17-23 of June 2013 (Hall 2B, C170).
