What is flux in metallurgy?

Flux is an essential mineral in metallurgy. It’s what helps turn scrap metal into new products. This blog post will explore the basics of flux and how it affects the metallurgical process. From what flux is made of to how it works, read on to learn everything you need about this essential mineral.


What is Flux in Metallurgy?

Flux is a material or process agent used in metallurgical processes to control the flow of molten metal. Fluxes are also used in other industrial processes, such as oil refineries and chemical plants.

In metallurgy, fluxes are usually made of either iron or aluminum and are used to remove impurities from the molten metal.

The most common type of flux is called slag flux. Slag flux comprises small pieces of iron or aluminum that have been heated until they liquefy.

These liquefied pieces form a liquid slag that flows easily when suspended in molten metal. The main purpose of using slag flux is to prevent the formation of iron oxide scales on the surface of the molten metal.

Another type of flux is called coke flux. Coke flux comprises small pieces of coal that have been heated until they liquefy. This liquid coke forms a thick layer on top of the melt and acts as a non-stick barrier between the molten metal and the workpiece.

The main purpose of using coke flux is to help prevent severe Hertzman contact problems (a dangerous phenomenon where contact between two metals causes an explosive reaction).

Types of flux in metallurgy

Fluxes are chemicals used in metallurgy to increase the flow of molten metal and other materials. Fluxes can be purchased as powders, liquids, or gases and are usually sold in porcelain containers or tanks. Some fluxes, like carbon, can also be used as solid fuels.

Role of flux in metallurgy

Flux is a material used in metallurgy that allows metals to be joined together during the manufacturing process. Fluxes are also used to remove impurities from molten metals.

Properties of Fluxes

Flux is a material property that affects how a metal can be drawn into a shape and released. Flux helps keep metals from sticking to each other and the workpiece. It also helps remove impurities from the metal.

Applications of Fluxes

Chemical fluxes are a type of fluid flow used in metallurgy. Flux can be defined as a “mixture of gaseous atoms, liquid atoms, or plasma” in which “an energy source outside the system causes the motion.” Applying chemical fluxes helps control the microstructure and physical properties of metals during processing. 

Fluxes can introduce elements into metal while it is still solid. This process is called fusion welding. Fluxes can also be used to remove elements from metal. This process is called deburring or machining. Fluxes can also improve the temperature distribution within a metal object. This process is called tempering.


In metallurgy, flux is an essential material used in various processes to clean and refine the metal being worked. Flux is responsible for transforming impurities into free-flowing metallic elements, which the smelting process can use.

It’s also important in oxidizing any existing oxides on the surface of metals so they can be removed completely.
