What materials are primarily used for marine connectors?

Marine connectors are primarily made from brass or stainless steel, often accompanied by corrosion-resistant coatings. This choice is crucial for ensuring durability and reliability in harsh marine environments where exposure to saltwater, moisture, and other corrosive elements is prevalent.

Brass and stainless steel possess excellent mechanical strength, making them suitable for the vibration and movement that occur in marine applications. Their inherent corrosion resistance is enhanced through coatings, which protect the metal from oxidation and degradation, thereby extending the life of electrical connections in boats and other marine vessels.

While plastic and rubber are indeed flexible materials often used for insulation and protection, they do not provide the necessary strength and durability for connectors which must withstand physical stresses and environmental conditions. Copper and aluminum are high-conductivity materials often used in wires rather than connectors themselves, focusing more on electrical properties rather than the mechanical and environmental durability required for marine connectors. Wood and fiberglass, while useful for certain applications in construction or insulation, are not suitable for connectors as they lack adequate conductive properties and can degrade when exposed to moisture.
