The Reasons of Choosing Brass Ferrules or Aluminum Ferrules

When considering picking which type of China left ferrules for your hoses, you firstly need to make clear the type of hose you will manufacture, what the hose will be used for in an industrial or residential application. If you make air hoses, most manufacturers as examples will use an aluminum ferrule for the application. If you produce water hoses, people commonly use brass ferrules.

One reason is the different results of brass and aluminum’ oxidation reactions in air and water. Oxidation is a sort of protective mechanism within these metals. It will create a type of scaling and tarnishing on the metal. When brass is properly sealed with a protective coating, it can fight off oxidation and last for a very long time. Even when oxidized, China brass adapter will still last for a long time before eroding away.

For aluminum ferrules, when the aluminium adapter in contact with water, the caked oxidation causes erosion that damages the metal permanently. If you have to use aluminum for ferrules, an anode aluminum is preferred, because it can handle freshwater and saltwater applications as the corrosion rate is slowed down.

The additional reason is ferrule shape and length. Aluminum ferrules have a length ranging from 0.500" up to 0.968" and can come in a smooth, cylindrical shape. While brass ferrules normally range from 0.500" up to 1.000" in length and come in a variety of shapes such as oval, ribbed, smooth and soaker.
