Conductive wire
Fine wire in stainless steel and precious metals
Round and flat conductive wire (magnet wire) in aluminium, copper-clad aluminium and copper. It's marketed under the Kanthal® brand, which is the trademark for resistance and conductive alloys within Alleima and offered in various product forms where wire is one.
It includes standard conductive wire sizes but also custom-designed sizes and
resistance to meet specific design requirements. The wire is available with or without insulation or coating.
Size range
Round wire
0.023-1.27 mm (0.0009-0.050 inch)
Ribbon (flat wire) / Square wire
Thickness: 0.023-0.635 mm (0.0009-0.025 inch)
Width: 0.038-2.032 mm (0.0015-0.041 inch)
Width/thickness ratio max 40, depending on alloy and tolerance
Conductive wire alloys
Aluminium
The Kanthal® program includes aluminium in three different conditions - bare aluminium, coated aluminium and anodized aluminium. The aluminium wire is used primarily as electrical conductors due to its inherent ability to rapidly dissipate heat and resist corrosion as well as its reduction in weight over other alloys. Kanthal® aluminium wire is widely used for hard disk drive coils, audio speaker coils with heat resistant enamels and high strength bond coats.

Copper-clad aluminium (CCA)
Kanthal® copper-clad aluminium (CCA) wire is available with 10% or 15% copper cladding over an aluminium wire core. CCA offers the inherent characteristics of aluminium while the copper cladding provides greater conduction of current and the ease of soldering of copper. Kanthal® CCA wire is used for electrical contact material and conductors.

Copper
Kanthal® oxygen-free high-conductivity copper (OFHC) has excellent physical, electrical conductivity and thermal resistance properties. Copper is easily soldered, welded and plated for excellent corrosion resistance. The alloy CDA 10100 has a purity of 99.99%, CDA 10200 has 99.5% and ETP C11000 has 99.9%.
