Introduction to Dezincification Resistant Materials

The significance of dezincification resistant (DZR) skin fittings cannot be overstated in the realm of boating. These materials are engineered to withstand the harsh environments of marine applications, ensuring reliability and safety on the water.

The Composition of DZR Materials

Traditionally, boat fittings have been predominantly made from metal alloys such as stainless steel, bronze, and brass. With the advent of plastic seacocks, the essential fittings for boats of all shapes and sizes have seen a shift in preference toward more durable options.

While stainless steel is recognized for its strength, its cost and susceptibility to corrosion have limited its use in many applications. Consequently, the focus has often been on copper alloys, especially the more progressive form of brass known as dezincification resistant brass (DZR).

Historical Context

The evolution of brass alloys can be traced back to ancient times. Over the decades, the understanding of how different waters can affect brass fittings has deepened. Especially in soft water areas, brass has been known to suffer from a corrosion issue known as dezincification, where zinc is leached from the alloy, leaving behind a porous and weakened structure.

Understanding Dezincification

The process of dezincification specifically affects brass with high zinc content—typically a 60/40 copper to zinc ratio. This issue first came to light in the late 1970s when yacht surveyors began reporting that fittings in seawater were also encountering this corrosion problem.

To combat these challenges, experts in metallurgy developed a modified version of 60/40 brass, standardized as CW602N. This new alloy provides enhanced resistance to corrosion while permitting high-volume production.

Advantages of DZR Skin Fittings

DZR skin fittings are utilized in a variety of components onboard, including ball valves, skin fittings, and elbows. The formulation of DZR materials guarantees not just strength but also resistance to environmental stressors commonly found in marine environments.

One notable feature is the ability of these materials to inhibit dezincification effectively. This is achieved by adding a controlled amount of arsenic to the alloy, which has been known to protect against dezincification since its first documented use in the USS Oregon in 1898.

Testing for Resistance

To ensure compliance with international standards for maritime use, DZR materials undergo rigorous tests. Notably, ISO 6509 specifies that any dezincification measured in hot forgings should not exceed 200 microns, ensuring durability in seawater for decades.

Identifying DZR Components

Within the boating community, identifying DZR components is essential. Initially, DZR brass fittings were marked with the letters CR (corrosion-resistant) forged into the body. Over time, as knowledge about corrosion-resistant materials has increased, more manufacturers now produce a variety of DZR components that are clearly marked as such.

It’s noteworthy that traditional brass fittings may be zinc or nickel-plated, giving them a shiny appearance, whereas DZR components tend to be unplated, which aids in identification.

The Impact on Boating and Rentals

With GetBoat.com always keeping an eye on developments in sailing and boating, the introduction of DZR materials is a crucial step toward ensuring the safety and longevity of boat rentals. These fittings may significantly influence the choices made by boat builders and owners, protecting them from costly repairs and improving overall satisfaction.
