Thermal shock: 260-300°C

Insulation thermoplasticity: 350-400°C

Temperature index (class) – the value at which the wire can operate at a constant temperature without losing its performance properties.

Thermal shock temperature – this parameter indicates the material's resistance to short-term exposure to high temperatures without insulation breakdown.

Insulation thermoplasticity temperature – the temperature at which the insulation begins to soften and lose its shape.

Copper has better electrical conductivity but is significantly heavier, which can increase the overall weight of the voice coil.

Aluminum wire is much lighter than copper, which reduces the coil's weight, but it has lower conductivity compared to others (to achieve the same resistance as copper coils, a thicker wire is required, which increases the outer diameter).

Copper-clad aluminum is lighter than copper, retaining aluminum's weight reduction benefits, and the copper coating improves conductivity compared to pure aluminum.
