Wire
Wire refers to long, slender metal products manufactured in continuous lengths through drawing or rolling processes. Depending on the base material and its mechanical, thermal, and electrical properties, wire is used in a wide range of industries—from electronics and automotive to medical devices and structural applications. Each wire type places its own requirements on non-destructive testing to ensure surface quality, structural integrity, and consistent process control.
Copper wire
Copper wire has high electrical conductivity, can be easily tin plated, and easily formed, which makes it a popular material. It is used in the automotive and computer sectors as well as in industrial electronics and household appliances.
Aluminum wire
Aluminum wire has a low density compared with other metal wire. This makes it possible to reduce the coil weight and therefore increase the efficiency with which the components to be moved are accelerated.
Austenitic wire
Austenitic wire, mainly made from stainless steel, is primarily used in medical technology. It has low electric conductivity, which presents special requirements for eddy current test systems.
Hot wire
The testing of hot wire places particular requirements on the systems as they have to work perfectly even at material temperatures of 1,200 °C. Test speeds of up to 120 m/s also have to be ensured.
FE wire before cold forming
FE wire is wire containing iron, as used prior to further processing in the form of drawing, bending, etc. Due to the high permeability of FE wire, it is absolutely necessary to pre-magnetize the material so that eddy current defect testing can be performed.
Steel wire
Steel wire has great break resistance and is corrosion-proof. It is used in applications such as medical devices, sieves, filters, in the textile sector, and for the production of wire rope.
Spring wire
Spring wire is specially shaped wire which is particularly resistant due to tempering. Spring wire is used for chassis springs, valve springs, etc. in the automotive industry.
Fine wire
The production of fine wire made from tungsten or platinum, such as used in the medical technology and automotive sectors, present s
