The composition of nichrome, typically 80% nickel and 20% chromium, contributes to its relatively low electrical conductivity compared to pure metals. The addition of chromium, while enhancing corrosion resistance and temperature stability, reduces the overall conductivity of the alloy. This inherent property makes it difficult to significantly improve nichrome's conductivity without altering its fundamental composition and potentially compromising its other desirable characteristics.

Temperature dependence poses another challenge for nichrome's conductivity. As the temperature increases, the electrical resistance of nichrome also rises, further reducing its conductivity. This temperature sensitivity can lead to inconsistent performance in applications where temperature fluctuations are common, necessitating complex compensation mechanisms in electrical circuits.

The surface properties of nichrome present additional hurdles in enhancing its conductivity. Oxidation and corrosion, although slower than in many other metals, can still occur over time, especially at high temperatures. These surface changes can increase electrical resistance at contact points, reducing overall conductivity in nichrome-based systems.

Manufacturing processes also impact nichrome's conductivity. Variations in production techniques, such as heat treatment and forming methods, can lead to inconsistencies in the alloy's microstructure. These variations can result in localized differences in conductivity across a single piece of nichrome, making it challenging to achieve uniform electrical properties.

The cost factor associated with improving nichrome's conductivity is significant. Developing new alloy compositions or advanced manufacturing techniques to enhance conductivity while maintaining nichrome's other beneficial properties can be expensive. This economic constraint limits the feasibility of certain research avenues and potential solutions.

Lastly, the environmental impact of nichrome production and use presents a growing challenge. As global focus shifts towards sustainable and eco-friendly materials, the energy-intensive production of nichrome and its limited recyclability become increasingly problematic. Improving conductivity while addressing these environmental concerns adds another layer of complexity to the ongoing research and development efforts in this field.
