C26000 Cartridge Brass – Composition, Properties and Uses.

C26000 Brass

If you are looking for a material with excellent corrosion resistance that is easy to manufacture and widely available, consider C26000 brass. This type of brass is a popular choice for a wide range of applications, from plumbing fittings to electrical components. In this post, we’ll explore what C26000 brass is, its composition, physical and mechanical properties, and its various uses.

C26000 Brass Composition

C26000 brass is a type of brass alloy known as cartridge brass. It mainly comprises copper, zinc, and a small amount of lead. The percentage of each element in the alloy varies slightly, but typically, C26000 brass contains around 70% copper and 30% zinc. The lead content is around 0.07%, which makes it easier to machine and form. This alloy has good machinability, and its lead content helps reduce tool wear and enhance the surface finish.

Element Content (%)
Cu 68.5-71.5
Fe 0.050
Pb 0.070
Other 0.15
Zn 28.5

C26000 Brass Physical Properties

The physical properties of C26000 brass make it an attractive option for many applications. It has a density of around 8.53 g/cm³, similar to copper’s. It’s also ductile and has good electrical conductivity. The melting point of C26000 brass is around 899°C, which makes it relatively easy to cast and form. It’s also reasonably resistant to corrosion, making it useful in environments where exposure to moisture or salt is a concern.

Properties Metric Imperial
Melting point-liquidus 954°C 1750°F
Melting point-solidus 916°C 1680°F
Density (@20°C/68°F) 8.53 gm/cm3 0.308 lb/in3

C26000 Brass Mechanical Properties

The mechanical properties of C26000 brass depending on the manufacturing method and the size of the material. Generally, this alloy has good tensile and yield strength, making it suitable for applications requiring good structural integrity. It has a Rockwell hardness of around 60, which is relatively soft and means this material is easy to machine and shape. This brass alloy is not particularly heat-treatable, so it doesn’t have significant changes in mechanical properties when subjected to heat.

Properties Metric Imperial
Tensile strength (depending on temper) 303-896 MPa 44-130 ksi
Yield strength (depending on temper) 76-448 MPa 11-65 ksi
Elongation (75mm/3in) 66% 66%
Poisson’s ratio 0.34 0.34
Elastic modulus 117 GP 16969 ksi

C26000 Brass Uses

C26000 brass has many applications due to its unique properties, such as excellent machinability, good electrical conductivity, and corrosion resistance. Some typical uses of C26000 brass include fittings, valves, hose couplings, and various electrical components such as fuse clips, sockets, and connectors. Its corrosion-resistance properties make C26000 brass popular for marine applications, such as boat hardware, fasteners, and throttle valves.

C26000 Brass Welding

Welding C26000 brass is a viable option, but it requires proper preparation and welding techniques to ensure a proper bond. The most suitable welding method is inert gas welding or TIG welding. It’s essential to note that C26000 brass contains lead, which can cause health issues. Therefore all measures to reduce exposure to lead fumes, dust, and particles should be observed.


C26000 brass is an excellent choice for various applications due to its excellent corrosion resistance, machinability, and unique physical and mechanical properties. Being a leaded alloy, it’s easy to fabricate and machine, making it a perfect material for complex, intricate parts. With this post, we hope we’ve helped you understand what C26000 brass is, its composition, physical and mechanical properties, and its various uses. Consider this material for your next project; you won’t be disappointed.
