Mar­tyr Alu­minum An­odes

Passage Maker - - Gear -

Mar­tyr leads the way in cad­mium-free an­odes, pro­vid­ing alu­minum an­odes for salt and brack­ish wa­ter, and mag­ne­sium an­odes for fresh­wa­ter ap­pli­ca­tions. Even though many boaters have changed over to alu­minum an­odes for salt­wa­ter use, many peo­ple still call them “zincs” as zinc has for a long time been the go-to an­ode to pro­tect against gal­vanic cor­ro­sion. How­ever, as alu­minum has come down in price, it pro­vides a vi­able al­ter­na­tive to zinc that con­tains a danger­ous by prod­uct, cad­mium. Cad­mium has long been known to have in­cred­i­bly dam­ag­ing en­vi­ron­men­tal ef­fects, and while the amount of cad­mium in zinc is small, it is needed to ac­ti­vate the zinc as the sac­ri­fi­cial me­tal. We award Mar­tyr full points for not only pro­duc­ing a bet­ter en­vi­ron­men­tal prod­uct to pro­tect boats against gal­vanic cor­ro­sion, but also for pro­vid­ing much needed ed­u­ca­tion in boat­ing com­mu­ni­ties on why alu­minum an­odes are the way to go for salt­wa­ter-based boats.
