What is CuVerro?
What is CuVerro Antimicrobial Copper?
CuVerro® is a solid surface that's a unique class of copper. The surface continuously kills 99.9% harmful bacteria1, when cleaned regularly, and is the latest innovation by Olin Brass, a global leader in copper-based alloys.
CuVerro is the only class of solid surface materials registered with the U.S. Environmental Protection Agency (EPA) to actively kill bacteria. The antibacterial properties work 24/7 in between cleaning, never washing out or wearing away, making CuVerro ideally suited for commonly touched surfaces where bacteria is a concern. Easy to maintain, CuVerro is tarnish-resistant and will not oxidize and turn green like pure copper.
Engineered for durability and strength with bactericidal efficacy, CuVerro® is EPA-registered, unlike additives. U.S. EPA testing proves copper's efficacy against infectious bacteria. Copper is the first solid surface material to receive this type of EPA registration.
CuVerro is antimicrobial, but it's also bactericidal, meaning it KILLS bacteria and does not simply inhibit bacterial growth.
How CuVerro is Used
CuVerro® antimicrobial copper surfaces create a new standard for cutting-edge product development and customization. Our alloys' manufacturability combined with beautiful aesthetics are ideal for innovative designers and manufacturers.

Bactericidal Copper Features & Benefits
CuVerro bactericidal copper is the ideal solid surface material for any location. It not only actively kills bacteria, but it's beautiful, too. These characteristics make CuVerro the preferred antimicrobial surface for anyone concerned about hygiene:
Cleaner Than Stainless Steel, Safer for Everybody
CuVerro antimicrobial copper begins killing infectious bacteria on contact and keeps killing it and unlike stainless steel and silver-based coatings, CuVerro continuously destroys and eliminates bacteria between cleanings no matter how many times it comes into contact with new, additional bacteria. CuVerro kills microorganisms so completely that the bacteria are not able to mutate or build a resistance.
CuVerro Kills Drug-Resistant Superbugs
Infections caused by superbugs like MRSA and E. Coli can be deadly. But they have a natural enemy - copper. One of CuVerro’s greatest strengths is that bacteria cannot develop a resistance to copper, it will continue to kill 99.9% of microbes forever. A healthcare environment with CuVerro copper will inhibit superbug bacteria from growing, and reduce the chance of transferring infection-causing bacteria among patients and staff. When cleaned properly, surfaces made from CuVerro antimicrobial copper kill over 99.9% of these superbugs, 24/7, and keep killing them continuously between cleanings.
CuVerro - One Product, Lots of Manufacturing Options
In addition to being incredibly effective at killing bacteria, CuVerro is also an extremely versatile material. It is used to create safer, antimicrobial fixtures, touch surfaces, and medical devices such as: over bed tables, nurse call pendants, bed rails, grab bars, faucet handles, sinks, and many others. CuVerro has even been used to create weight-training equipment that fights the spread of germs in fitness and rehab facilities.
Cleaner, Safer Medical Facilities
CuVerro creates a strong defense in the fight against Healthcare Associated Infections (HAI’s). Outfitting a facility with antimicrobial copper creates a cleaner environment that continually and actively kills the germs responsible for HAI’s, even between cleanings. State of the art facilities such as the Cleveland Clinic, Kaiser Permanente, and Memorial Sloan Cancer Treatment Center use products made with CuVerro that are helping to make an impact on public health.
Copper and copper alloys are active surfaces and will develop an oxide called a patina over the course of 2-4 weeks if washed and cleaned using existing agents and protocols. Once established, the patina is stable and protects the component from further oxidation unless it comes into contact with strong reagents. The developed patina does not reduce efficacy according to results from laboratory testing and clinical trials.
There are three types of cleaning products to consider – see below. For any product specific information, it is recommended that the manufacturer is contacted.
Disinfectant products containing metal-ion chelators, such as EDTA, should be avoided, as these partially and temporarily inhibit copper’s efficacy. The Copper Alliance is working with leading companies to support the development of cleaning and disinfection products that work synergistically with copper alloys.
1) Hospital Detergents – these will clean grease and other soil from surfaces and should always be used prior to disinfection.
- Most cleaning products are proprietary and will have instructions for use – always refer to manufacturers’ instructions.
- Items should be cleaned, dried (disinfected as necessary) and inspected before use.
- If applying disinfectant after normal cleaning, it is common to wash with clean water and dry between these steps to ensure optimum activity of disinfectant.
- Cleaning wipes are single use products and should be disposed of after use.
- Some products may combine disinfectants with detergents and allow single-step use.
2) Hospital Disinfectants - these will disinfect the surface of the copper and generally contain:
- Alcohols - not corrosive to copper alloys, but not active against all microbes.
- Bleaches - containing chlorine or with the active ingredient sodium hypochlorite; the solution is not corrosive to copper alloys when used correctly.
- Quaternary ammonium – such compounds do not damage copper alloys.
- Ammonium chloride - is of little concern for copper when used in normal dilute formulations.
- Phenol and ammonia - are rarely used organic chemicals and are not harmful to copper.
Other disinfection techniques:
- Hydrogen peroxide (solution or vapour - HPV) has no long-term effect on copper alloys.
- Steam may be used for cleaning or disinfection and will not harm copper alloys.
- Formaldehyde is sometimes used for laboratory disinfection and fumigation and is not deleterious to copper or copper alloys.
3) Metal Polishes and Cleaners - these will brighten the appearance of the copper and copper alloys.
- Citric acid-based cleaners are preferred as they disinfect and remove tarnish without leaving a residue.
- Proprietary polishing products, such as Brasso, will clean the copper but are not recommended as they may leave a residual film which inhibits the antimicrobial effect of copper for a period of time. Removal of this residue can be difficult but may be achieved with alcohol wipes.

CuVerro® is made from up to 100% recycled copper material and is 100% recyclable. In fact, nearly all of the copper mined to date is still in circulation because the recycling rate of copper is higher than that of any other engineering metal.
The bactericidal properties of copper are inherent, so no additives are required. For healthcare environments especially, copper provides the assurance of no VOCs (volatile organic compounds), PVC (poly vinyl chlorides), phthalates or other pollutants that can adversely impact air quality. In keeping with the environmentally friendly properties of copper, no sealants, glue, or adhesives are used in the manufacturing processes of CuVerro®.
Copper has played a role in Green Building, and has been one of the materials of choice for energy efficiency and sustainability, and a mainstay in solar, wind and wave renewable energy systems.
The EPA has evaluated the acute toxicity of copper and found there to be "no risk to public health." Since early human existence, copper has been an essential material in many applications.
