DIN 3093 Oval copper ferrules are intended to be installed with a hydraulic crimper using round dies. They may be used on mild, black, galvanised, and stainless steel wire ropes. Ferrules made of copper (plain or nickel plated) are used together with stainless steel wire ropes to take advantage of the reaction between them which  helps avoid galvanic corrosion.
For a given wire diameter, the choice of DIN 3093 Ferrule size and die size depends on the Fill factor of the rope that is being swaged.
The dimensions table below (based on Talurit data) applies to wire ropes made of stainless steel single layer steel wire ropes with round strands and rope grade G304 (A2) to G316 (A4). Data is valid when wire ropes should conform to EN 12385-4 and 5. The types of rope should be either Right Hand Ordinary Lay (RHOL) or Lang Lay (LL).
For different grades of wire rope and higher fill factor, please consult with your engineer in charge.
Note that stainless steel as a material is not included in the EN standard for wire ropes.
