No... There is no evidence that copper bracelets are any more useful than a hologram, or an ion bracelet, or a piece of amber, etc. (See below for a minor caveat.) Any effect that could be out there is nothing more than the [placebo effect] (Link to abstract on placebo effect for this specific mechanism)1.
If you had read the linked question, you should ask yourself the same question as from that answer:
This is an excellent opportunity to practice grass roots skepticism. Ask yourself: By what mechanism is this supposed to work? How does the proposed mechanism align with what we know about science, biology, physics, etc.? Also, you may be interested to know that in some countries, Power Balance must state that they have no actual scientific backing for their claims. The Placebo band is just as effective, and much cheaper.
To directly answer your question, The University of Arkansas for Medical Sciences clearly states:
Myth: Wearing a copper bracelet can cure arthritis.
Reality: Arthritis is a condition that results in deterioration and loss of the joint surface cartilage, basically the repair process fails to keep up with the breakdown. Copper bracelets have long been sold as a cure for arthritis, vendors propose that the metal is absorbed through the skin and helps cartilage regeneration. But there are certain facts you should know before you rush out and buy that bracelet, says Dr. Randy Bindra, director of the Center for Hand and Upper Extremity Surgery at UAMS. “Copper is a component of some of the normal cellular enzymes and we require very small amounts of copper in our daily diet,” says Dr. Bindra. Mineral-rich foods include vegetables (potatoes), legumes (beans and peas), nuts (peanuts and pecans), grains (wheat and rye) and fruits (peach and raisin). “Copper deficiency is extremely rare and most regular diets provide enough copper to meet the daily requirements. Supplementation is only needed in patients with other serious medical conditions that affect their gastrointestinal tract and impair their ability to absorb nutrients.” While it’s never been proven that copper can copper be absorbed through the skin by wearing a bracelet, research has shown that excessive copper can result in poisoning, causing vomiting and, in severe cases, liver damage. “This can be seen after ingesting foods boiled in copper vessels or from contamination of water from corroding copper pipes. In reality no modality of treatment has been shown to cure or reverse the changes of arthritis,” says Dr. Bindra.
All these silly assertions are nothing more than marketing schemes... As the University of Maryland Medical Center states (emphasis mine):
Copper bracelets are often marketed to people with both osteoarthritis and rheumatoid arthritis as a way to relieve symptoms, but there' s no evidence that they work.
The University of Maryland page also has an extensive reading list that may help you go to actual scientific sites that do tell you what copper is actually good for though (it does have uses, which is what charlatans will use to make their distorted claims). If you search reputable sources, you will find a distinct lack of evidence. It is best to practice good baloney detection for things like this.
As the University of Maryland page shows, there are some uses for copper, however, these are ingested routes. Topical applications are also known in some compounds that use copper as a binding peptide. Neither of these involve the wearing of a copper band, nor does the band display any mechanism by which it would even simulate the useful uses...
