(.008 inches thick) 32 gauge: The 8 mil copper is approximately 11 - 12 times thicker than typical household aluminum foil and 1.5 times thicker than the 5 mil. This is a heavy-duty tooling foil. 8 mil can be cut fairly easily with scissors and is still very pliable. It may hold shape a little better than the 5 MIL , but will not bear much weight and will yield to increasing pressure.
(.010 inches thick) 30 gauge: These sheets are approximately 14 times thicker than household aluminum foil and are twice as thick as
. Beginning with the 10 mil, the copper is less foil-like in appearance and response to pressure. It is still rather thin as it would take 100 sheets stacked on top of each other to equal an inch, but it is more rigid than the thinner material and at this thickness the copper will begin to hold weight and maintain shape significantly better. The 10 mil copper (also known as 30 gauge) weighs approximately 7.4 ounces per square foot. Despite being more rigid, the 10 mil is still pliable and you can easily create a 90 degree bend with your hands. It can be cut with heavy duty scissors and or a utility knife. It responds well to hammering and other texturization applications. 10 mil is often used in outdoor projects to protect wood from the elements, such as for flashing, or capping poles or exposed beams in a structure. It is also used for birdhouse roofs and other garden projects. Our 10 mil copper was featured in This Old House magazine (June 2007) as it was used to create an outdoor water feature. It is also used in indoor projects such as creating an inset in wooden cabinets or covering furniture (see the photo gallery for examples) and although it is a lighter gauge copper, some customers have chosen this thickness for creating copper tabletops, copper bartops, copper backsplashes and copper countertops.
(.016 inches thick)26 gauge: The 16 mil is approximately 1.5 times thicker than the
. It would take approximately 62.5 sheets of
stacked on top of each other to make an inch. Also called 26 gauge, the 16 mil copper weighs approximately 12 ounces per square foot. It is significantly more rigid and less pliable that the thinner material, but will also hold weight and can be bent/ formed into shape by hand or with tools. It is a very durable. It can be cut with tin snips, shears or a utility knife with a heavy duty blade. 16 mil is often used for sculptures, jewelry-making and other arts and crafts projects. Our customers have used the 16 mil for copper backsplashes, copper bar tops, copper countertops, and copper range hoods as well as roofing projects (see the photo gallery for information about creating a
from 16 mil copper) and other outdoor structural projects where the durability of the material outweighs the need for more pliability.
(.0216") 24 gauge: 16 ounce copper sheeting is a heavy weight copper often referred to as "roofing copper" or "roofing flashing." It weighs approximately 1 pound per square foot. It's often used for roofing and flashing, various art and craft projects, DIY projects such as copper backsplashes, copper countertops and copper range hoods, electrical applications, research and development and much more. 16 ounce copper can be bent and formed by hand but is very durable. Metals snips are needed to cut this thickness. (Also check our patina copper sheets for a variety of uses including bartops and countertops. It is also used for for various wall hangings and artwork.)
(.032") 20 gauge copper sheeting is heavyweight copper. It is approximately 50 percent thicker than 22 mil and weighs approximately 1.5 pound per square foot. It's often used for various construction, art and craft projects, DIY projects, electrical applications, research and development and much more. 20 Gauge copper can be cut with heavy duty snips or sheet metal shears. While you can bend this copper with your hands, to get a sharp 90 degree bend, you must use a sheet metal brake.

40 Mil/18 Gauge (.040") 18 gauge copper sheeting is heavyweight copper. It is approximately twice as thick as 22 mil copper and weighs approximately 2 pound per square foot. It's often used for various construction, art and craft projects, DIY projects, electrical applications, research and development and much more. 18 Gauge copper can be cut with heavy duty snips or sheet metal shears. It is very difficult to bend by hand. Check out this video on the various tools used to cut sheet copper: https://www.youtube.com/watch?v=BAkoeagvweA
