Circles

Circles are round, flat discs that are made from metal sheets, including steel, aluminum, stainless steel, copper or brass among others. These metal circles are employed in a number of uses because of their thickness and size measuring capabilities. They are used as raw materials in the manufacturing of parts, components or ornaments. Circles are widely applied in automotive industries, construction industries, machinery industries and decorative and architectural arenas.

Different Circles Materials

Here are different types of circles based on their material and manufacturing process:

Steel Circles: These circles are made from carbon steel, mild steel or alloy steel and are characterized by high strength and long lasting nature and are commonly used in construction industries.
Stainless Steel Circles: Stainless steel circles are used in areas where the ability to withstand corrosion and have high strength is needed, such as in the ability to resist rust and staining.
Aluminum Circles: Aluminum circles are light in weight and do not corrode easily and are used in places where weight and resistance to corrosion are critical.
Copper Circles: Copper circles are highly appreciated for their heat and electrical conductivity and are used in electrical, plumbing and air conditioning industries.
Brass Circles: Brass circles are popular for their corrosion resistance and beauty and are widely employed in decorative parts and for applications where strength and machinability are needed.
Nickel Alloy Circles: Circles are manufactured from nickel based alloys that provide excellent corrosion and heat resistant properties for their application in severe conditions.
Galvanized Steel Circles: The circles are made of steel that is coated with zinc to protect it from rusting and therefore can be used in areas exposed to moisture.

These different types of circles offer a large variety of properties and advantages for a wide range of industrial and ornamental uses.

Different types of Circles

Here are different types of circles based on their manufacturing process and characteristics:

Seamless Circles: Unlike other circles that are fabricated by joining different pieces of metal, seamless circles are made from a single piece of metal. They provide uniform strength and are normally applied where high strength and a smooth surface are desired.
Welded Circles: Welded circles are made by welding different pieces of metal together; thus, they can have seams. They are affordable and can be used in areas where appearance is not a major factor or where the structure does not have to be concealed.
Hot-Rolled Circles: These circles are made from hot rolled metal sheets and are manufactured through high temperature forming which is easier to do. Hot rolled circles are comparatively less smooth as compared to cold rolled circles and are used where exact dimensions and surface finish are not required.
Cold-Rolled Circles: These circles are manufactured using cold rolled metal sheets and hence they have a better finish and closer tolerances because of the cold rolling process. They are ideal for use where higher precision and smoothness of the surface of the component is desired.
Perforated Circles: Holes or slots that have been made on circles for the purpose of lightening the circle, increasing the flow of air, or for aesthetic reasons.
Expanded Metal Circles: These circles are manufactured by drawing a metal sheet into a net like structure to give strength and lightness; they are used where ventilation or drainage is needed.

The above different types of circles are used to meet the different needs for industrial use, decoration, and functionality.

Features of Circles

Here are the key features of circles:

Shape: Circles are round and have equal thickness at any point which makes them ideal for bearing loads and stress.
Material Variety: Circles can be made in steel, stainless steel, aluminum, copper, and brass with their own characteristics such as hardness, rust resistance, and heat conductivity.
Thickness Options: Circles can be made in various thicknesses making it possible to order one depending on the strength and weight desired.
Surface Finish: Circles can have polished, brushed, or coated surface which improves their aesthetic appeal as well as adds some extra features such as anti-corrosive or low friction properties.
Durability: In terms of the properties of the material, circles provide very good wear resistance, and resistance to corrosion and impact, which makes them suitable for use in conditions that are considered to be severe.
Precision: As preformed to specific size and standard deviations, circles provide close fits where necessary and where there are strict standards of measurement.
Easy Fabrication: Circles can be easily cut, drilled or altered in any way that may be required making it easier to use them.

These characteristics make circles a useful and consistent material for a large number of applications in industry and commerce.

Applications of Circles

Here are some applications of circles

Manufacturing Components: Circles are employed as raw materials for manufacturing of different mechanical parts, gears, and other mechanical components which need round shapes.
Automotive Industry: Circles are used in the fabrication of car parts such as gaskets, washers, and brake discs where round shapes are important.
Plumbing: Copper is one of the most common metals that is used in plumbing systems as flanges, washers, and sealing because of its strength and resistance to corrosion.
Construction: Circles are employed in construction in base plates, flanges and other structural members which need a circular cross-section for shape and stability.
Electrical Applications: Circles made of conductive metals such as copper and aluminum are employed in electrical contacts, conductors, and grounding applications because of their high conductivity.
HVAC Systems: In HVAC systems, circles are applied to flanges, connectors and seals to ensure that there are no leaks in the heating, ventilation, and air conditioning system.
Food and Beverage Industry: Stainless steel circles are used for food processing and packaging equipment since they do not rust and are easy to clean.

The above applications show how circles are useful and can be used for various industrial, commercial and ornamental purposes.
