In perusing brass sales, manufacturers of shipbuilding components usually evaluate metals based on one key property among many: corrosion resistance. This property – the selling point of special alloys like naval brass – enables the metals used for ship components and apparatus to withstand the damaging effects of salt water and air, plus other chemical reactions at sea Otherwise, damage from corrosion can compromise the strength and efficiency of a ship’s structure and machinery. It can compromise the safety of the people onboard – even the environment itself.
Note that while rust is the most obvious sign of corrosion, it’s only one type of it. Other vital signs include paint blistering, and the appearance of powder-like white stuff on metal. This substance eats away the exposed surfaces, creating cavities in the metal.
