4. Types of Sheet Metal Materials
1. Stainless Steel
For starters, stainless steel is one of the most frequently used materials. It is not pure metal but an alloy. Its composition is 11% of chromium content and 1.2% or less of carbon content. The rest is iron and other alloying elements if necessary.
This material has superior corrosion-resistant properties. It is also heat-resistant and chemicals-resistant. From storage tanks to kitchen vessels, stainless steel offers reliability and great durability.

2. Brass
Brass is another popular alloy that contains about 84% of copper and 16% of zinc. This material has greater electrical and thermal conductivity and good corrosion-resistant properties. But the real kicker of this material is its appearance. From shiny gold to bloody red, brass with different contaminants can be of any color to your desire.
3. Aluminum
Aluminum is a metal with numerous minor and significant features. It is not costly and can undergo machining as laser cutting or milling. It is absolutely non-toxic. Aluminum also has great corrosion-resistant properties, even without a finish. As a bonus, this material can be recycled multiplied times.
In fabrication, several grades of aluminum can be used. Each of them has a unique set of properties. As an example, Grade 1100 metal has low strength but is weather-resistant. Grade 6061 is strong but not formable. The choice of metal is always a compromise between one or another property to find optimal ones for a specific manufacture needs.

4. Galvanized Steel
How to enhance already great material such as steel? To cover it with another metal, obviously. By integrating zinc into sheet steel’s surfaces through hot dipping, galvanized steel is obtained. It is even more corrosion-resistant and durable. Galvanized steel is a common material for automobile parts.
5. Mild Steel Sheet
Mild steel is another type of steel containing about 0.05-0.025% of carbon. It is also called “low carbon steel.” Basically, mild steel contains mostly iron with some other alloying elements in small proportions.
Mild steel sheets are highly ductile, machinable, and weldable than flat pieced made from other materials. This metal also has some magnetic properties, but its tensile strength is rather low.
6. Alloy Steel
Alloy steel is something that is difficult to characterize. And here is the reason why. The resulting properties may vary when many alloy elements such as vanadium, silicon, nickel, manganese, copper, chromium, and others are added to carbon steel.
Basically, the proportions of alloying elements define the features of these materials. Basically, there are two types of alloy steel: Low-alloy and high-alloy steel. The first category has the containment of all the alloying elements up to 8% of the weight in total. If the proportion of alloying elements exceeds this limit, a material obtained is considered high-alloy steel.
7. Corrugated Sheet Metal
And the last one is corrugated sheet metals. They are made of steel coils by forming thin layers into metal panels. This process is called “roll forming.” Corrugated sheet metals are perfect for roofing as they can withstand severe weather conditions. Typically, a few coils of different materials are used to form a sheet piece of metal with the properties required.
