Introduction
Brass, an alloy primarily composed of copper and zinc, is prized for its strength, corrosion resistance, and aesthetic appeal. In its flat-rolled form, brass strip is used extensively in electrical, architectural, automotive, and engineering industries. However, not all brass strips are created equal. Different compositions and properties make each type suitable for specific industrial applications. In this blog, we’ll explore five common types of brass strips and their practical uses, while also highlighting how top brass products manufacturers in India meet the needs of global industries with precision and reliability.
1. Cartridge Brass Strip (C260)
C260 brass, also known as cartridge brass, contains around 70% copper and 30% zinc. It offers excellent ductility and strength, making it ideal for deep drawing and cold working. Its balance of mechanical and conductive properties makes it a top choice in both electrical and mechanical applications.
Industrial uses:
Ammunition casings
Electrical connectors
Radiator cores
Decorative hardware
This type of brass strip is popular where a combination of formability and corrosion resistance is required.
2. Free-Cutting Brass Strip (C360)
Known for its outstanding machinability, free-cutting brass (C360) contains lead to improve cutting speed and surface finish. This makes it suitable for CNC machining and precision parts that require tight tolerances and smooth finishes.
Industrial uses:
Gears and pinions
Screws and fasteners
Electronic components
Watch and clock parts
C360 brass strip reduces tooling wear and speeds up manufacturing, especially in high-volume production environments.
3. High Tensile Brass Strip (C485/C678)
This type of brass is specially alloyed with small amounts of iron, manganese, or aluminum to increase strength and wear resistance. High tensile brass strips are often used in marine and heavy-duty engineering industries where mechanical stress is significant.
Industrial uses:
Naval fittings
Bearing cages
Bushes and wear plates
Structural applications
Its resistance to seawater corrosion also makes it a good alternative to bronze in cost-sensitive projects.
4. Leaded Brass Strip (C353/C356)
Leaded brass strips offer a good balance between machinability, corrosion resistance, and formability. They are used in applications that require light machining with minimal friction and a smooth finish. The presence of lead makes them easier to cut and drill.
Industrial uses:
Plumbing fittings
Valve parts
Hinges and lock bodies
Ornamental applications
This type of brass strip is commonly used in the sanitary and hardware industry where both aesthetics and performance matter.
5. Yellow Brass Strip (C268)
With about 66% copper and 34% zinc, yellow brass offers a brighter golden color and good corrosion resistance. It is less ductile than C260 but still highly workable. It’s often chosen for its visual appeal and good strength.
Industrial uses:
Lamp bases
Nameplates
Musical instruments
Architectural accents
Yellow brass strip combines form and function, making it ideal for decorative yet functional products.
Tough Pitch Copper: A Powerful Companion
While brass strips serve a broad range of mechanical and aesthetic functions, certain electrical applications demand higher conductivity. That’s where Tough Pitch Copper comes into play. With nearly 100% IACS conductivity, it is commonly used in busbars, switchgear, and transformer components—often alongside brass components for hybrid assemblies.
Conclusion
Each type of brass strip serves a distinct industrial purpose, and selecting the right one is essential for ensuring performance, cost-efficiency, and durability. Whether it’s C260 for electrical terminals, C360 for machined parts, or C268 for decorative fittings, understanding the properties of each grade is key to making the right choice. Supported by top brass products manufacturers in India, global industries can count on consistent quality, customized supply, and fast delivery for their non-ferrous material needs.
