Advantages:
Machinability: Brass is one of the easiest metals to machine, leading to faster production and lower costs.
Corrosion Resistance: Brass is naturally resistant to corrosion, especially in water, making it ideal for marine and plumbing applications.
Attractive Finish: The bright, gold-like appearance of brass makes it desirable for decorative applications.
Electrical Conductivity: Brass alloys offer good electrical conductivity, useful for connectors and terminals.
Limitations:
Material Cost: Brass can be more expensive compared to other metals like aluminum or steel.
Softness: Brass is relatively soft, which makes it more prone to scratches and dents compared to harder metals.
Weight: Brass is heavier than some alternative materials, which may be a limitation in weight-sensitive applications.
