Copper ferrules are commonly used with Stainless Steel Wire Rope to avoid galvanic corrosion.
Aluminium ferrules are generally used for galvanised steel wire rope.

Stainless steel ferrules are suited to stainless steel wire rope to achieve the best possible resistance against corrosion.

Swaging is a process that terminates the end of a wire rope, either by creating an eye loop or simply adding a stopping point on the wire. A Swaging Sleeve is used to bind/splice a loop in a cord or hold back the end of a cord from passing beyond a fixed point. 
There are two major categories of swage sleeves- oval sleeves and stop sleeves. Oval sleeves are egg-shaped or hourglass-shaped and designed to install eyes in a wire rope. Stop sleeves function more like bolts, creating a critical end to a wire rope without requiring a loop to be applied. 

Stop sleeves are sometimes also called buttons or button sleeves. A stop sleeve is a usually circular shaped sleeve that attaches at the end of a wire rope. It anchors the line in a similar manner to how a bolt anchors a nut or screw. This creates a termination point at the end of a rope and will prevent the end of the rope from slipping through gaps and holes in other materials. Stop sleeves are not as strong as oval sleeves but are a simpler way to swage a cord as they do not require a loop or eye to be formed in the line. Our stop sleeves will stop fraying and are more solid alternatives to wire clips and thimbles. 

The oval sleeve is a standard egg-shaped swage sleeve that is designed to bind the end of a wire rope into a loop. 

Duplex sleeves are more commonly called hourglass sleeves or double barrel sleeves, and like oval sleeves, they are engineered to bind together eyes in wire ropes. These are the smoothest Cable Crimp Sleeves and as the name implies, they are made in the shape of an hourglass. Our Duplex Sleeves are available with zinc or tin plating to add resistance to corrosion, or made from copper or aluminum. The aluminum Duplex Sleeves come in several different variations.
