Edward Mirell incorporates Black/Silver Titanium Cable into its creations. It is considered a memory alloy, as it maintains a predetermined profile under severe abuse. It is for this reason that titanium memory cable is widely used in medical and optical industries. The cable is made with 74 strands of titanium wire that, to touch, possess a soft and silk-like feel. There are many casted and low-grade reproductions, but few, if any, deliver the same look, versatility and quality as the Black Titanium Memory Cable used in the Edward Mirell collections. They have a life time guarantee on any of their collections.
