Both are mixtures.
A copper door with a knob is a mixture. The copper door is a pure substance made of copper, while the knob may be made of a different material like steel, brass, or plastic. The combination of these two different materials forms a mixture.
A copper door knob is a mixture of copper and other elements or compounds that form the alloy used to make the door knob. Copper itself is an element, but when combined with other elements or compounds to form an alloy, it becomes a mixture.
it is a mixture
A copper door knob is a mixture, as it is made up of a combination of copper metal and potentially other elements or compounds depending on the specific door knob design (e.g., other metals for strength or decorative finishes).
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).

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.
