The Advantages of Stainless Steel versus Silver-Clad Copper Wire for use as Medical Extrusion Core Wire
■Silver-clad copper (Sil-Cop) wire is often selected for use as medical extrusion core wire due to its biocompatibility and elongation characteristics. However, it has been observed that the silver cladding may flake when used in this type of application, leaving residue in equipment and finished catheters. An alternative material, such as 300 series stainless steel, has comparable performance and compatibility. As a single alloy wire, it eliminates the risk of flaking.
●Introduction
■The performance of stainless steel extrusion core wire was tested against Sil-Cop to compare overall diameter profile, percent diameter reduction, and force requirements. Various sizes of each wire type were put under an axial load and elongated. Once elongated, the diameter of the wire was measured at points along the length of the sample. The force required to elongate and reduce the diameter of the samples was also measured and compared.
