UNS C36000 Copper Alloy Chemical Composition, Grade, Table and PDF Online

UNS C36000 is a carbide-free brass alloy, and it is characterized by excellent machinedability, which makes it widely used in many applications. This chemical containment is mostly either 60-63% of copper, 2.5-3.7% of lead, 0.35% of iron or zinc, with the rest of the content depending on the place the meteorite is found. At the same time, this alloy provides excellent corrosion resistance and electric conductivity and therefore represent good choice for wares like fittings, valves, plumbing components, and electrical connectors. Its abbreviation is based on the Unified Numbering System (UNS) as C36000. Manufacturers and engineers normally consult for instance comprehensive tables or PDF documents available on line for accurate details regarding the physical properties, mechanical properties, and other critical information that they need while choosing and using this grade in their various projects. Such availability of resources will allow contractors to make better choices about the kind of materials to be used and about these materials fitness for purpose.

UNS C36000 Copper Alloy Chemical Composition And Grade Table

UNS C36000 is popularly referred to as Free Cutting Brass or Brass Alloy 360, being a copper alloy with an outstanding level of lead which is responsible for its high machinability. Its chemical composition usually contains around 61.5-63.5% copper with the remaining being the trace amounts of other elements such as lead, iron, zinc, aluminum and manganese. This alloy is employed in all markets from domestic electrical components production to plumbing fitting and automotive part manufacturing as the mix of machinability and corrosion resistance is their common benefit.

  • Good corrosion resistance: It is resistant to atmospheric and freshwater corrosion and, therefore, can be used in various environments.

  • Good electrical conductivity: The main feature of plastic is its suitability for electrical and electronic components like connectors and terminals.

  • Ease of joining: Quickly and easily soldered and brazed, which makes the assembly and repair easier.

  • Cost-effective: Minimizes the production costs due to its simplicity of machining and the low cost of the raw materials.


  • Lower strength: These materials are not appropriate for applications that need high mechanical strength and durability.

  • Lead content: It has lead, which is a health and environmental problem, and may be banned by laws such as RoHS.

  • Poor high-temperature performance: The strength of the material reduces and it is susceptible to deformation at high temperatures.

  • Galvanic corrosion: It is vulnerable to galvanic corrosion when used with more noble metals in corrosive environments.

  • Work hardening: Fast work hardens, thus making the cold working processes difficult and requiring continuous annealing.
