This is from the link as I was thinking about copper splashback would be easier/cheaper than brass to work.

22 Mil/16 Ounce Copper (.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 sheetsfor a variety of uses including bartops and countertops. It is also used for for various wall hangings and artwork.)
