Aluminum Voice Coil Vs Copper Voice Coil

Jun 09, 2013 · Aluminum requires more cross section area to do the same job. Aluminum has lower mass than copper giving the ability to move the same current, albeit through a larger conductor than copper, but with an overall reduction in mass. The larger surface area of aluminum can have an advantage in a voice coil when it comes to the length of the coil windings. An aluminum coil

Sep 22, 2013 · Aluminum has lower mass than copper giving the ability to move the same current, albeit through a larger conductor than copper, but with an overall reduction in mass... The larger surface area of aluminum can have an advantage in a voice coil when it comes to the length of the coil windings.

Copper vs. aluminum voice coils? | Yahoo Answers. Mar 07, 2009 · Copper doesn't last longer. The main difference is you will have a longer winding on the coil with aluminum than copper to acheive the same thermal potential. Chat Now Send Inquiry; aluminum or copper voice coil? - Car Audio Forum. Aluminum cools faster but I thought part of the job for the former and the gap is to cool the coil?

Mar 08, 2009 · Copper doesn't last longer. The main difference is you will have a longer winding on the coil with aluminum than copper to acheive the same thermal potential. Copper will give a …

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.

Dec 04, 2016 · aluminium is much lighter which lowers MMS which gives greater efficiency which means a louder sub most of the times. copper is a better conductor but usually you can only do minimal wounds before its weight messes with the efficiency of the sub so cooling factor is actually not that great.

Aluminum has 61% of the conductivity of copper. An aluminum conductor’s cross-sectional area must be 56% larger than copper for the same current carrying capability. The need to increase the thickness of aluminum wire is a consideration in its use in tight voice coil gaps—especially as it expands more than copper voice coils when hot.

Apr 15, 2012 · Copper is a somewhat (~1.7x) better conductor than aluminum, but is much (~3.3x) heavier. So, the latter is a better choice overall, since minimizing the mass of the voice coil is important. Silver is not used for the same reason.

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.

Mar 09, 2010 · The disadvantages to 4" coils is the weight of the coil, how it effects the parameters of the speaker. Typical aluminum coil is about 3 times what a 3" coil is. And when you go to copper, well, a copper 4" coil will weight about 6-10 times what a typical 4" coil weighs. This picture here, shows a HX2 Power 4" coil far right, its copper

Apr 21, 2015 · Aluminum — For air-tight enclosures, such as autosound subwoofers or home theater subwoofers, the voice coil’s mechanical strength can be increased with a single layer aluminum collar. As with aluminum bobbins, expect an increase in eddy currents (and their secondary effects) if the magnetic structure does not use a copper cap or aluminum ...

3 Because the copper line set, copper coils, and fins are aluminum, where the copper joins the aluminum, it is subject to galvanic corrosion. Galvanic corrosion will occur when two dissimilar metals pressed together.

The main difference is you will have a longer winding on the coil with aluminum than copper to acheive the same thermal potential. Chat Now Send Inquiry Voice coil - Wikipedia, the free encyclopedia

Feb 13, 2002 · But many manufacturers consider cost, which is why aluminum can be found in condensing coils today. “Aluminum is roughly the same price per pound as copper, but you use three times as much copper in a copper coil. It does have an impact on manufacturing costs,” says Williams.

The voice-coil is the part of the speaker that the output of the amplifier is directly fed to, and they get hot when driven hard. As amps began to get drastically more powerful, folks started to look for another material to wind the voice-coil on; one that could take a lot more heat.

Jan 31, 2018 · Copper vs aluminum coil. I know a copper voice coil is the standard coil used when reconing most subwoofers . It’s light , a great conductor , good thermal rating , and lower FS than an aluminum coil. My question is when doing a heads up comparison to the two , with the aluminum coil’s capability of having a high FS affect its ability to ...

Feb 05, 2009 · Not in the voice coil scenario at least. It's not the durability - it's the melting point. If you overheat the coil, an aluminium coil will burn through before a copper one; that's all. The melting point of aluminium is 660.25° Celsius (933.40° Kelvin).

Nov 26, 2006 · Fig.1 also includes plots for the less commonly used voice-coil materials aluminum (red trace) and silver (purple), which behave very similarly to copper. Although special alloys of significantly lower temperature coefficient of resistance are available, such as nichrome and manganin, these also have much higher resistivity, which unfortunately makes them unsuitable for use in voice-coils.

Apr 16, 2012 · What is the bigger voice coil going to do for sound vs small voice coil drivers... I have another thread in "help me choose eqt" (help me choose a new mid ... It's a balancing act but typically you can specify lots of aluminum or copper in the coil and offset the eddy currents through other means. The shorting rings themselves help in cooling too.

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.

When given a specific application to build towards, we can pick from these options to provide you with the very best coil for YOUR particular application.

The voice coil's electromagnet is placed within a permanent magnetic field. The two magnets interact, and every time the electromagnet's polarity changes, the interaction between the magnets changes. When the magnets are repeatedly repelled and attracted, they move the coil back and forth quickly, kind of like the piston in an engine.

A Nomex voice-coil former (above) yields a high level of sound quality plus a much higher heat dissipation compared to paper. For many speaker applications Nomex is the ideal voice-coil matierial (especially for bass or mid drivers). Unfortunately it is rarely used today (except for some famous Celestion guitar speakers).

Morel speakers with EVC™ technology utilize voice coils that are up to three times larger than those used in conventional loudspeakers. The EVC™ design moves the magnetic drive system to within the voice coil, eliminating stray magnetic flux by effectively directing all the magnetic energy to the voice coil.

Aug 13, 2008 · The thickness and material (aluminum is better than copper in this regard) of the electrical conductor used to wind the VC. The larger the conductor, the lower the current density in it. (If our conductor is doubled diameter, it will have 4 times the surface area (and mass) and can take 4 times as much current for equivalent conductor heating.

Feb 22, 2019 · Let's postulate an aluminum wire 4 inch coil vs a heavier copper wire 3 inch coil. As you stated, the 4 inch coil is limited by its diameter. But a heavier smaller coil might not be able to reach the point where its diameter becomes a factor due to mass …
