Metals are rarely used in industry in their pure form. Instead, so-called alloys are often used. They improve the properties of a metal and allow targeted adaptation to different requirements.
But what exactly is an alloy? Which metals are combined with each other and why? And where do we encounter alloys in everyday life? In this article, you will learn the most important basics about alloys.
What is an alloy?
An alloy is a metallic material that consists of at least two chemical elements. At least one of the elements must be a metal. By specifically mixing different metals, new materials with modified properties are created. These can, for example, be harder, more corrosion-resistant or easier to machine than the respective pure metal. The difference from a pure metal is therefore that alloys are specially developed to meet certain technical requirements.
Which metals are frequently alloyed with each other?
There are numerous proven combinations in metal processing. The following metals are particularly often alloyed with each other:
- Aluminium with magnesium or silicon for higher strength and corrosion resistance
- Iron with chromium and nickel to produce stainless steel
- Copper with zinc to produce brass
- Copper with tin to produce bronze
By adding further metals, the properties of a material can be specifically improved. This creates materials that are optimally matched to their later area of use.
Well-known examples of alloys in everyday life
We encounter alloys every day – often without noticing it. Typical examples are:
- Stainless steel in kitchens, railings or household appliances
- Brass in fittings, hardware or musical instruments
- Bronze in sculptures, bearings or coins
- Aluminium alloys in vehicle, aircraft and mechanical engineering
Many modern products would not even be possible in their current form without alloys.
How does an alloy influence the properties of a metal?
The greatest advantage of alloys is that material properties can be specifically changed. Depending on the composition, alloys can:
- increase strength
- improve corrosion resistance
- reduce weight
- increase hardness
- optimise machinability
- increase temperature resistance
This allows materials to be matched exactly to the requirements of different industries and applications.
Custom metal – the right alloy for every application
The choice of the right alloy plays a decisive role in the functionality and service life of a component. Depending on the application, different aluminium, stainless steel or copper alloys are used.
At METALXACT, you receive numerous metal products in different materials and alloys – individually configurable and precisely manufactured to measure.
Frequently asked questions about alloys
What is an alloy?
An alloy is a material made from at least two elements, at least one of which is a metal.
Why are metals alloyed?
To specifically improve properties such as strength, corrosion resistance or machinability.
Is stainless steel an alloy?
Yes. Stainless steel consists mainly of iron and contains, among other things, chromium and often nickel.
Our conclusion: alloys make metals more powerful
Alloys are indispensable in modern metal processing. By combining different metals, materials with optimised properties are created that are essential for numerous applications in industry, trade and everyday life.
Whether stainless steel, brass or aluminium alloys – they ensure that metals become more resistant, more durable and more versatile.
