Brass Grades and Properties
Brass is an alloy composed of copper and zinc, with small amounts of other metals added to improve its properties. Various brass grades are available, such as C260, C272, C360, and C464, each with unique properties. For instance, C360 brass has excellent machining properties but is unsuitable for welding, while C464 brass has high corrosion resistance and is commonly used in marine applications. Understanding the properties of each brass grade is crucial when selecting the appropriate material for CNC machining.
By understanding the properties and characteristics of these common brass grades, you can make informed decisions and select the best material for your project.
Brass Grade | Properties | Ductility | Machinability | Corrosion Resistance |
---|---|---|---|---|
C260 | Also known as cartridge brass, C260 is a popular choice for general-purpose applications. It has excellent formability and is often used in the manufacturing of ammunition casings, electrical connectors, and decorative hardware. | High | Good | Good |
C272 | This grade is commonly used for architectural purposes due to its good strength and corrosion resistance. It is suitable for applications like door handles, hinges, and other hardware. | Medium | Good | Good |
C360 | Known as free-cutting brass, C360 offers outstanding machinability. It is ideal for machining complex parts and components, such as gears, valves, and plumbing fittings. | Low | Excellent | Fair |
C464 | Also called naval brass, C464 is prized for its exceptional corrosion resistance, especially in saltwater environments. It is suitable for marine applications, including propellers, shafts, and fasteners. | Medium | Good | Excellent |
- For projects requiring high ductility and formability, C260 is an excellent choice.
- If you need a brass grade with good strength and corrosion resistance for architectural purposes, C272 is a solid option.
