Core materials

Copper

X

Copper is mainly used in the wire sector due to its excellent electrical and thermal conductivity. It enables efficient current transmission with minimal energy loss, making it ideal for applications in electronics, power supply and communication. Copper is also corrosion-resistant, mechanically robust and easy to process (e.g. drawing), making it a preferred material for wires and cables.

Steel / Iron

X

In the electronics sector, steel/iron is mainly used as a core material in conductors or shielding, often with platings such as copper, nickel or tin to improve electrical conductivity and corrosion resistance. It is used, for example, in shielding wires, magnetic components or mechanically stressed connections. The high tensile strength of steel is an advantage for robust electronic applications.
PDF data sheet
Copper alloys

X

Copper alloys are used to improve properties such as strength, corrosion resistance and temperature stability. Alloys such as copper-beryllium, bronze, brass and other alloys offer a good balance between mechanical robustness and electrical conductivity, which is why they are used in spring contacts, high-current cables or aggressive environments. They are ideal when pure copper is not mechanically or thermally sufficient.
PDF data sheet
Stainless Steel wires

X

Electroplated stainless steel wires are used to make the surface electrically conductive and improve solderability, as stainless steel has a naturally low conductivity. Platings such as copper, nickel or tin ensure a better electrical connection and at the same time protect against corrosion. This combination is ideal for applications in aggressive environments or for long-lasting electrical contacts. Thanks to their robustness and stability, they are ideal for durable, resilient connections in demanding applications.
PDF data sheet
Nickel

X

Pure nickel is used due to its excellent corrosion resistance, good electrical conductivity and high temperature resistance. It is particularly suitable for applications in chemically aggressive or hot environments, such as heating elements, thermocouples or cables in the chemical industry. Nickel is also used as a base for electroplated platings or as resistance wire.
PDF data sheet
Composite materials

X

Composite materials such as CCS (Copper Cladded Steel) and CCA (Copper Cladded Aluminium) combine mechanical stability with good electrical conductivity. Thanks to the high tensile strength of the steel and the conductivity of the copper, CCS is ideal for mechanically stressed wires that need to have low resistance. CCA offers low weight thanks to aluminum and at the same time improved conductivity due to copper, which makes it ideal for lightweight power cables, especially in the aviation and automotive industries. Both materials are economical alternatives to pure copper in demanding applications. We also offer CCS37E, a material with a stainless steel core, for extreme mechanical stress and high conductivity.
PDF data sheet
Nickel alloys

X

Nickel alloys are used to increase corrosion resistance, heat resistance and mechanical stability. They offer good electrical conductivity and are ideal for applications in extreme environments, such as high-temperature or chemically aggressive areas. Examples are nickel-chromium wires for heating elements or nickel-copper wires for maritime applications.

Plating materials

Tin

X

Tin is mainly used in electroplating as corrosion protection and for solderability. It protects metals such as steel, copper or brass from oxidation and is often used in electronics, e.g. for printed circuit boards or electrical (plug-in) contacts. Tin platings are also non-toxic and environmentally friendly.

Matt tin plating has a rough, non-reflective surface that is particularly suitable for applications with high soldering requirements, as it enables excellent wetting.
Tin melted

X

Tin is mainly used in electroplating as corrosion protection and for solderability. It protects metals such as steel, copper or brass from oxidation and is often used in electronics, e.g. for printed circuit boards or electrical (plug-in) contacts. Tin platings are also non-toxic and environmentally friendly.

The advantage of a matt, melted tin layer lies in its homogeneous and oxide-free surface, which ensures excellent solderability. Melting also eliminates possible micro-cavities or stresses in the layer. The surface is shiny after melting.
Bright Tin

X

Tin is mainly used in electroplating as corrosion protection and for solderability. It protects metals such as steel, copper or brass from oxidation and is often used in electronics, e.g. for printed circuit boards or electrical (plug-in) contacts. Tin platings are also non-toxic and environmentally friendly.

Bright tin-plated contacts are characterized by a smooth, reflective surface that offers very good solderability and corrosion resistance.
Tin/Lead

X

Tin/lead is used in electroplating, particularly in the aerospace industry, as it offers excellent solderability and prevents the formation of tin whiskers. The alloy is chemically resistant and stable at high temperatures, which is why it is also suitable for critical applications in aggressive environments.
Tin/Indium

X

Low-melting solders in the wire area enable soldering at low temperatures, which is particularly gentle on sensitive components and PCBs. They often contain metals such as tin, lead, bismuth or indium and are ideal for applications where temperature limits must be maintained. This reduces the risk of heat damage and deformation.
Tin/Bismuth

X

Low-melting solders in the wire area enable soldering at low temperatures, which is particularly gentle on sensitive components and PCBs. They often contain metals such as tin, lead, bismuth or indium and are ideal for applications where temperature limits must be maintained. This reduces the risk of heat damage and deformation.
Tin/Bismuth/Silver

X

Low-melting solders in the wire area enable soldering at low temperatures, which is particularly gentle on sensitive components and PCBs. They often contain metals such as tin, lead, bismuth or indium and are ideal for applications where temperature limits must be maintained. This reduces the risk of heat damage and deformation.
Tin hot-dip tinned (Sn and SnPb)

X

Hot-dip tinning produces a more robust tin layer, which is particularly suitable for mechanically resilient and corrosion-resistant wires but is less uniform and often has a slightly lower soldering quality.
Nickel

X

Nickel is used in electroplating on wires as corrosion protection and a diffusion barrier. As a final layer, it prevents materials such as copper from migrating through and ensures a durable, resistant surface. It is also often used as an intermediate layer to improve the adhesion of other platings such as tin or gold.
Copper

X

Electroplated copper thick platings serve primarily as a conductive layer. It offers excellent electrical conductivity and often serves as an intermediate layer to improve the adhesion of nickel, tin or gold. It also protects the wire as a final layer against oxidation and mechanical wear.
Silver

X

Silver is used because of its excellent electrical conductivity and good oxidation resistance. It improves electrical performance and is often used for high-frequency applications or in electronics. It also provides a durable, solder-friendly surface, ideal for plug contacts and connecting elements.
Hard Gold

X

Hard gold is used to create an extremely durable and conductive surface. It offers excellent corrosion and wear resistance as well as high electrical conductivity, making it ideal for highly stressed contacts and applications in electronics. The addition of cobalt increases the hardness and abrasion resistance compared to pure gold. Classification according to ASTM Type I-II, Grade C-D
Fine Gold

X

Fine gold is used on wires to create an extremely corrosion-resistant, highly conductive and also drawable surface. It is particularly suitable for sensitive electronic applications as it offers excellent contact quality and does not oxidize or lose conductivity. Due to its softness, fine gold is mainly used for applications where no high mechanical loads occur. Classification according to ASTM Type III, Grade A
