In Reply to: RE: That Ebay store is full of copies/fakes posted by tweakydee on July 12, 2010 at 19:18:34
If you go into their store, there are tons of Oyaide Look-alikes. This particular store does NOT call them Oyaides (though other stores have tried) but gives them numbers alike 079, which ARE numbers Oyaide uses to designate their plugs.
These particular R-Copper plugs are not fakes since they don't claim to be made by any particular famous company. I'm just pointing out their other items for sale. On the other hand, do people know what "R-copper" exactly means? I presume it stands for "Rose Copper," since the same color copper blades are featured on Iego plugs, which are called Rose Copper. I have used these Iego plugs, which are good plugs. Hopefully, these no-name plugs use same high-quality Furukawa copper like Iego.

After looking at these and some of the other brands sold by the same seller, plus others on ebay and elsewhere, I am seeing a number of them labeled as red copper. However I haven't found if red copper is a better quality than regular OFC copper. There are also a lot of items now in red copper such as rca jacks, rca plugs, spades, banana plugs & interconnects, etc. Looks like its being marketed widely. They are reasonable priced though, with so many coming out & available now it looks like market pressure is making the prices more competitive. They have a variety of plated ones too.
Somehow, unless they are getting BIG bucks from us audio junkies for it, I doubt that "red copper" is more expensive as a material than regular "pure copper" as usually used in better equipment (Furu for example).
It's probably an alloy that is cheaper to produce; copper prices have gone through the roof in recent years, hence the massive theft of pipes and wiring from buildings!
Try this on for size from Wikipedia: "Red brass is both an American term for the copper-zinc-tin alloy known as gunmetal, and an alloy which is considered both a brass and a bronze. It typically contains 85% copper, 5% tin, 5% lead, and 5% zinc.[25] Red brass is also an alternative name for Copper Alloys C23000, which is composed of 84-86% copper, 0.05% iron and lead, and zinc.[26] It may also refer to ounce metal, another copper-zinc-tin alloy." I suspect that it's what we see as red copper in the ads.... http://en.wikipedia.org/wiki/Brass
Or try this one: "Brasses (C83300-C87900 and C89320-C89940) are copper alloys in which zinc is the dominant alloying addition, because of their excellent castability, relatively low cost and favorable combination of strength and corrosion resistance, brasses are by far the most commonly cast copper alloys. There are six subcategories of cast brasses; red and leaded red, semi red and leaded semi red, yellow and leaded yellow, high strength and leaded high-strength yellow (manganese bronzes), silicon brasses/silicon bronzes, and copper-bismuth (Cu-Bi) and copper-selenium-bismuth (Cu-Se-Bi) brasses. Red brasses: The cast red brasses (C83300-C83810) are alloys of copper, zinc, tin and, in some cases, lead. A “red” copper like color is evident in alloys containing less than about 8% Zn." ...From http://www.atlasmetal.com/brass-bronze.php
Copper is naturally a reddish color when in pure form. If it's more than the usual copper color and seems more reddish, then it must be an alloy or an oxide of some sort.
I did some more reading and it does seem that red copper (copper zinc lead tin) is really a higher-copper content (85%) form of brass, the higher percentage of copper makes it red and also softer, which makes machineability better. Wiki says it is considered both a brass and a bronze. I also found one reference that says "Red Copper has better electrical conductivity than Brass. " so while its not pure 100% copper it may be better than standard brass based connectors. Other copper alloys are phosphor bronze(70% copper, tin and phosphorous) and beryllium copper (97% copper and beryllium).

if you ask me to guess, i think these are Brass not copper. the red colour might give the impression that they are unplated copper but in fact very often they are plated brass. file off a bit and you will see whether they are copper or not.
and sold on ebay as "high quality" you can usually bet it's cheap junk.
Never attribute to malice that which can be adequately explained by stupidity.
