C37000 is copper alloy, and it is well known that it gives good machinability and satisfactory corrosion resistance. Usually, its chemical composition includes copper (Cu) as the main element, while other trace elements slightly present are Lead (Pb) and some others. It is known from the examples such as plumbing connections, valves, and other electro-mechanical components that this brass is widely used. It shows high level of solderability and brazability making the material can also be employed in joining processes. Our UNS C37000 alloy is available in different grades. Each one is designed with specific requirements in mind, providing a choice between different mechanical properties and ease of machining. The ability to list the chemical makeup, mechanical properties, and grades of this material in the form of tables, chart and PDFs has continued to strengthen the link between engineers and processors as they choose material and during processing.
The alloy blessed with high machinability and corrosion resistance, UNS C37000 - also classified as Free-Cutting Brass - deservedly enjoys a good reputation among the engineering community. It is the composition of a customary 60-63% copper, 2.5-3.5% lead and a max. of 0.35% iron. However, it is easily workable to various uses. Because it has good thermal and electrical conductivity, it is often applied in electrical connection pieces, plumbing fittings, and complicated parts. This circulates lead which increases machinability to lead it to be used in high-speed operations. The chemical composition and the chemical serial number show that the product is suitable for a wide range of industrial applications as it is able to function not only in high-performance but in the most demanding tasks.

Advantages:
Excellent machinability: Perfect for high-speed machining operations, it cuts down the production time and the cost.
Good corrosion resistance: Suitable for use in atmospheric and freshwater environments, protecting against general corrosion.
High strength and hardness: It offers durability and wear resistance, thus it is appropriate for applications that are robust.
Easy to solder and braze: Allows people to work in plumbing, electrical, and mechanical assemblies, thus, making the fabrication processes easier.
Good electrical conductivity: Electric components work effectively when it comes to energy transfer, so, the method is efficient for electrical components.
Disadvantages:
Lead content: Improves machinability but is also a health and environmental hazard, therefore, its use is limited in potable water and food-related applications.
Lower corrosion resistance in acidic/marine environments: Not applicable for highly acidic or marine conditions, thus needing more specialized alloys.
Limited formability: Not suitable for applications which require extensive forming or bending operations, thus limiting the shaping of the material.
Potential for dezincification: The material is prone to zinc loss in acidic/high-chloride conditions, which in turn, will result in a decrease of mechanical properties and integrity.
Higher cost: The cost of this alloy is higher compared to some other non-ferrous alloys and steels, which affects the budget-sensitive projects.
