Aluminum vs Copper Voice coil for Daily Pounding ...

Copper coils are good for smaller sq subwoofers. Alum coils work much better for anything that takes alot of power or is for spl. For example our new sonance v.2 has a 50mm tall coil. the copper one weighed almost 300 grams. the high temp alum weighed 128.5 grams. the spl diffrence would have been a good amount @1w and there would have been a much higher chance for defect.

[Differences] Copper vs Aluminum Coil for Air Conditioning

Oct 11, 2020 · In some categories like durability, heat transfer and ease of maintenance, the Copper coils have a clear advantage.

Voice Coil Material — Polk Audio

actually - and I don't know why - brass was often used in the old days for voice coils in woofers and extended range drivers. Aluminum was also common, probably because on a per dollar as well as on a a per gram of mass basis, its conductivity is very high. Copper's a good default, though. 0.

Aluminum voice coils? Why? | Headphone Reviews and ...

Apr 15, 2012 · I'm pretty sure that copper is a far better thermal conductor than aluminum, and will dissipate the heat far faster, since it has a much lower specific heat capacity than aluminum. However, it is very expensive in large quantities which is why it isn't used in heatsinks much, and it's also more difficult to manufacture into heatsinks.

RESISTANCE OF COIL

If we hold the winding length fixed, say at 17.88 inches, then the 1000 ft of aluminum wire will fit on a coil of 624 turns and 6.121 inches diameter. The inductance is now 17,670 µH, larger but still less than that of the copper coil. The aluminum coil has more resistance and less inductance than the copper coil, both undesirable.

Coil Wire - What specifictions do I need to know?

Coil wire will almost always be made of either copper or aluminum, though silver wire is used in rare cases, such as loudspeaker voice coils. Copper is the highest conducting non-precious metal, so aluminum's lower conductivity means it needs a much larger cross-section of aluminum to achieve equivalent ratings to a copper wire.
