Perhaps an alloy of Osmium and Iridium, the two densest metals known. however I suspect an alloy of Iridium with an interstitial dopant in solid solution (perhaps a small element which could fit between the iridium atoms) might be more dense. Osmium is quite toxic when oxidised so I wouldn't bother with it.
An alloy is a solution of a metal dissolved in another metal. This forms a homogeneous mixture with properties different from those of the individual metals.
No, brass is not a pure metal. It is an alloy made by combining copper and zinc in specific proportions to create a material with unique properties such as increased strength and corrosion resistance.
A metal alloy mixture of two or more metals and a solution is a mixture of two or more substances so they are the same.
Stainless steel is an example of an alloy that is not metal plated. It is a combination of iron, carbon, and other elements like chromium and nickel, naturally forming a protective layer on its surface that prevents it from needing additional plating.
A solid solution of a metal or nonmetal dissolved in a metal is called an interstitial solid solution. This occurs when smaller atoms (such as nonmetals) fit into the spaces between the larger atoms (metals) in a crystal lattice. This allows for the formation of a homogeneous solid mixture with improved mechanical properties.
Osmium is the densest metal, you can use google for figuring out the rest.

Iridium is the second densest naturally occuring element after osmium; the two are quite close in density. There are several synthetic radioactive elements which are thought to have much higher densities, but since only a few atoms of these have ever been produced and a piece large enough to see would vaporize itself, it's really a purely theoretical matter.
The densest alloy known to date is osmium-iridium alloy. It is known for its exceptional hardness, high melting point, and resistance to corrosion. These unique properties make it stand out among other materials in terms of durability and stability.
That metal, if it is a pure elemental metal. Each element that makes up the alloy, if it is a metal alloy.
Iridium
Osmium with a density of 22.6 g/cm cubed
Iron is not an alloy - it's a metal element. An alloy is a mixture of two or more elements.
The densest element on Earth that matches your description is osmium. Osmium is a rare, extremely hard, bluish-white transition metal. It is the densest naturally occurring element.
An alloy?
Siver Halides are neither a metal or an alloy. They are a salt.
The term "base metal" or "parent metal" in an alloy refers to the primary metal that forms the majority of the alloy's composition. It serves as the foundation of the alloy, with other elements added to enhance its properties. The base metal determines the alloy's primary characteristics and properties.
