Silver-wound strings vs. regular strings
Instruments: What are the difference between silver-wound strings and regular aluminum-wound strings?

Are there any differences (for example, tone or durability) between strings with silver winding those with regular aluminum? I'm just wondering whether silver-wound strings are worth the extra dollar. (By the way, the strings in question are the Dominant G and D strings)
Silver-winding gives a softer, warmer sound than aluminum. It is particularly beneficial on the lower strings.
No idea about durability.
I actually think silver strings can create a brighter sound as compared to aluminum. The silver Dominant D is significantly thinner than the aluminum Dominant D, and I feel that the thinner string generally produces a brighter sound.
What will work best depends on the violin it is used on. I['ve tried both silver and Al (especially) D strings and found that on some violins I prefer the Al string because it seems to have more "breadth" of overtones that gives amore mellowed sound that vibrato can do moore with 9at least for me on those fiddles).
i think it may be partly because being lighter (lower density), Aluminum winding requires a thicker string that would naturally have overtones somewhat "detuned" from the "infinitely thin theoretical ideal."
Well, technically, different metals have different physics: mass, tensile strength, density, hardness, heat conductivity, melting point, etc. Metals are wound onto strings to give mass, and therefore change the inherent pitch of the core material, and the physics of the metals will all combine to create a unique tone. I would agree with Andrew: in my limited experience, I have found the silver wound strings to be brighter in sound than the Al strings. The choice between Ag and Al would seem to depend upon your preferences and violin.
Now, what I want to know is why other metals are not used. The inherent limitation of AL, AG, CU, etc is the oxidation of the metals. If inert metals were used, eg gold or platinum, strings could last much longer.
The Dominant Silver D is thinner in diameter than it's aluminium counterpart. The sound is different - perhaps not brighter but on some violins more focused. It is a personal choice in the end.
Silver makes it kinda ring more than aluminum. But for E strings Gold will really make it ring.
The information I posted was given to me by techs at both Thomastik and Pirastro. They most likely know their stuff.
I've also A/B'd a few sets of silver & aluminum A strings (when "5 string" audition sets are provided, and the silver A's were softer everytime.
I image other factors (such as diameter) might come into play in certain circumstances, but that is the correct technical answer to the original question.
I think the silver-wound D's are brighter. What you pick entirely depends on the fiddle and th sound you like. Silver is a harder metal than aluminum so the silver wrapped strings are somewhat more durable.

I think this is not correct--aluminum is a more brittle material than silver. That's why al bikes have the rep for a stiffer rider. Also, I doubt absolute hardness dicates string longevity. It's more likely the winding.

BTW--aluminum is the material of choice for various bicycle components that must be light and very stiff: derailleurs, chainrings, rims, hubs, brake calipers/levers, etc. It's also used in the aircraft industry for the same reasons. I'm sure if silver were harder, it would be used in some of these applications.
silver is better because you can melt the silver to get silver bullet to kill the lycanthropes living in your house under your bed.
I'm deathly allergic to silver. Makes me die and stuff. Someone give me a rare steak before I break down and eat my student.
we haven't been keeping in touch for a while!
By the way are you a lycanthrop?
That would be intriguing
The parameters for string wrapping:
Modulus of Elasticity
(*edit) Surface Texture (see Burgess' post below)
Density: for a given lineal grams per centimeter, a more dense winding will produce a thinner string. This may be "good" or "bad" depending on what the goal is.
The hardness is not terribly important. Even the tensile strength is not particularly important for a winding. (It is important for the core, and in fact determines the maximum pitch achievable for a given material on a given scale length).
The modulus of elasticity is independent of hardness and strength and is a fixed number for a given metal, regardless of the particular hardness. This parameter affects the elastic response of the string and therefore the sound. Silver is only slightly greater (higher modulus of elasticity) than aluminum, and yet it is much more dense. This makes for a lower characteristic frequency for a given tension (PSI, not force, LBS). )However this is a winding material, and so the winding angle and the plastic deformation during the winding affect the contribution of the silver or aluminum so it is not a simple effect of the density to modulus ratio.)
For an infinitely thin flexible string, the modulus has no effect on the resonant frequency. However, strings are not infinitely thin, and the bending stiffness of the string (which is proportional to the modulus of elasticity) affects the harmonic contributions and this applies to the winding as well. One effect of a winding is to stiffen the string, and therefore the winding angle, the thickness, and modulus of elasticity of the winding affect the sound.
In the end, it is as the doc says: a matter of preference.
From Ron Gorthuis;
"Now, what I want to know is why other metals are not used. The inherent limitation of AL, AG, CU, etc is the oxidation of the metals. If inert metals were used, eg gold or platinum, strings could last much longer."
Ron, one of the reasons outer winding materials are chosen is how they interact with rosin (according to Thomastik). For example, oxidation on aluminum forms microscopic pits which become filled with rosin, making aluminum wound strings more "grippy", all other things being equal.
While uncovered nylon strings are popular on guitar, they aren't used on violins partly because the bow doesn't grip them well. If you've ever used a bow with nylon "hair", you have a sense of this difference in sensation.
I just put on an (Al) dominant d.. it seems more focused.. as far as warmth i'd say it's still pretty much same im still getting similar overtones if it were (Ag) silver..

I broke my D string and went to the local 'Edmond Music' store to buy a new one. However, they refuse to carry silver violin strings citing that "schools prefer the aluminum ones because when players start out they sound less 'squaky'". Has anyone here ever heard an excuse like that before? It's definitely a first for me.
After extensive work on rebuilding my violin to achieve a beautiful voice and ease of playability my final struggle is with strings. I guess what I am looking for is the string that will give me the sound I want the violin to produce. I say that because my violin body cares little for noble metals ... it just wants to pass on vibrations. Whatever it takes to achieve the sound I am after is what I will use. And, that may change as my tastes change. I put on some pricey synthetics and felt uncomfortable with how they responded to the touch, the sound was great. I ran back to the steel for consistency.They felt better beneath my fingers. I also noticed that I can use a different type of string for each four to achieve the quality of sound I'm looking for. What my violin can do with a silver G has a different value that what silver might do with a much lighter A. I am enjoying the exploration and the freedom to explore the sound qualities and and what the violin seems to be calling for to achieve them.
Silver is denser than aluminium, so the windings will be thinner for the same tension, but they are also more fragile. A more interesting tone, but a shorter life.
Adrian, aluminum windings seem to be less wear resistant than silver windings. If you look at the underside of an aluminum D which has been used for a while, it will have a flat area where it comes into contact with the fingerboard. As this wear occurs, the string is no longer uniform density along its length, and you have a "false" string.
If you look at a silver-wound string which has been used for the same amount of playing, it will show much less of this wear.
David, I agree that aluminium is less tough than silver, but I find that silver windings, being thinner, break a little sooner at bridge and nut, or in the pegbox,( even with my well prepared notches!)
And whatever Thomastik write, I find silver viola D's (Dominant or Obligato) brighter and more responsive than their aluminium versions, presumably because they are thinner.
This part of Gamut's website gives a lot of useful information concerning copper/silver/silver-plated copper wound gut core lower strings for the violin and viola. Because Gamut is primarily (but not exclusively) a Baroque/Early Music string maker, aluminum is not mentioned.
My personal preference for the violin G has long been gut core wound with copper or silver-plated copper (not necessarily Gamut).

I would like to try strings wound with depleted uranium.
Why waste your time with the depleted stuff?
Get the full, hot, uranium 235 fresh from the centrifuge. Best used with a carbon control rod...er...bow, to keep things under the critical point. Playing these strings for the finale of the 1812 overture are particularly recommended.
Here's the Nevada Desert Symphony Orchestra trying out the latest U-235 strings (I think they're from Pirastro)
