Both are mixtures.
One can purchase a brass door knocker from the following retailers: Amazon, Brass Gallery, The Door Knocker, Black Country Metal Works, eBay, Home Depot, Home Base, B&Q, Trade Me, Jefferson Brass, to name a few.
Brass door handles are available from a wide range of retailers. For the best selection, shop at a hardware store or a home improvement store. Superstores will also carry a limited selection of brass door handles. If a specialty handle is needed, contact your local locksmith.
They do not conduct as much heat as other door handles do.
You can go on Baldwin Hardware's website. You can also go into popular DIY stores and buy Baldwin brass door knobs from there. Alternatively, you can buy them online to Door Knob Discount Center.

Both are mixtures.
it is a mixture
Copper (Cu) is a chemical element.
If all the components are made from pure copper - yes, all is from the chemical element copper.
Metals can be elements, yes, however, most that you would see on a day to day basis i.e. cookware, door handles, etc. Most of these metals are alloys, which are a mixture of several elemental elements. For example, brass, a common door handle metal, is a mixture of zinc and copper. So, to find out the elemental metals, look at a periodic table.
Doors vary in composition and are rarely composed of a single element. Many doors are made of wood, which is not an element but a mixture of compounds. The primary component is cellulose, a compound of carbon, hydrogen, and oxygen. Doors may also be made of various metals such as aluminum, iron, steel (a mixture of iron, carbon, and possibly other metals), and galvanized metal (metal coated with a layer of zinc).
brass is an alloy a mixture of zinc and copper, this makes it much easier to shape into a door handle and it corrodes less. first question i answered yeah feeling smart :D and a tad gay that i could be bothered to type this yeah

Door is not a compound word.
Brass handles didn't rust.
