CR-Brass- An alloy that lasts
For decades, brass (MS58, equivalent to CW617N) has reliably served on board, providing decent corrosion resistance when polished regularly. In underwater applications, MS588 can achieve the EU-demanded standard of five years' functionality as long as it does not come into contact with electrolytic reactions. Electrolytic reactions can cause dezincification, whereby zinc is flushed out of the brass alloy, leaving the remaining copper brittle. The solution to this problem has been known for years: DZR brass (dezincification-resistant), also known as CR brass (corrosion-resistant) or
CW602N. CR brass contains tiny amounts of heavy metals mixed with a copper content of 63%. This specific alloy significantly prolongs the lifespan of board feedthroughs, water inlets, and thru hulls. Although CR brass is rather expensive, we always recommend its use in underwater applications because dezincification can occur in any body of water, including rivers and lakes. However, this problem is fairly easy to spot. After removing the layers of paint and oxidation residue, a pink discolored material will remain: this is the copper from the original alloy. If you discover this on your vessel, you should replace the affected components.
Note:
To fit the flush-mounted grommets, a spanner with a flat width of 68 mm is required.
