What is Alloy?
Describes the composition of a mixture of metals. Most metals are a mixture of other elements and compounds.
They are mixed to maintain stability and durability of the metal for objects like coins or billions.
The amount of precious metal in a bullion or a coin can be described as a percentage. The price of metal is always measured in a troy ounce, not standard ounces. Alloys are defined by their metallic bonding properties and are either categorized as homogenous, made up of a single-phase, or heterogeneous–consisting of two or more phases.
They have multiple purposes and are used across a variety of industries and sectors, including construction, automotive manufacturing, surgical, aerospace, and luxury/fashion manufacturing. The use of alloys across industries can also be attributed to the overall cost-saving and durability elements. A few of the most popular metals used in jewelry, particularly in engagement or wedding rings, are alloys.
For example:
- Rose gold is a combination of the metallic elements, gold, and copper
- White gold is a combination of the metallic elements, gold, and silver
- Sterling silver is a combination of the metallic elements, silver, and copper
Commonly used building materials such as steel or silicon steel are alloys produced when elemental iron and non-metallic carbon or silicon are combined.
Since alloys are pervasive and necessary for the functioning of multiple industries, they are often seen as a good investment strategy, since they hold their value–in most cases–more than paper dollars which is often impacted by trends in the stock market and subject to inflation. Additionally, because alloys are used globally, they are often used as an index to measure a countries growth and general economic health. The global demand for alloys, and the correlated strength of investment, is supported by the continuous population growth, urbanization, and technological innovation.
