What is it called when you mix two metals together?

Hint: To answer this question, we first need to understand what metals are. A metal is a material that has a glossy appearance when freshly produced, polished, or shattered, and conducts electricity and heat reasonably well. Metals are either malleable or ductile (they may be hammered into thin sheets). Metals can be chemical elements like iron, alloys like stainless steel, or molecular compounds like polymeric Sulphur nitride.

Complete answer:
The resulting product is generally referred to as an alloy when two distinct metals are combined together in a specific ratio. Additionally, an alloy can be created by combining a metal with an element that is not necessarily a metal.
Alloy - A substance created from the mixing of two or more metals is referred to as an alloy. Combinations of metals and other elements can also be used to create alloys. The properties of alloys are frequently dissimilar to the qualities of their constituent components. When compared to pure metals, alloys frequently have greater strength and hardness. Red gold, which is made by combining copper and gold, is an example of an alloy. White gold, which is made by combining silver and gold, is another major gold alloy.
Some commercially important alloys are:
- Steel
- Nichrome
- Bronze
- Brass
- Duralumin
- Solder
So, we conclude that the mixture of two metals is known as alloy.

Note:
Dental amalgam is formed by combining liquid mercury with a solid alloy of silver, tin, and copper. Some alloys may contain trace amounts of zinc, mercury, and other metals. Amalgam alloy is the name for this mixture of solid particles. The ISO Standard for dental amalgam alloy controls the composition of alloy particles in order to manage features of set amalgam such as corrosion and setting expansion.
