About Brass
Brass is an alloy of copper and zinc, known for its excellent machinability, corrosion resistance, and aesthetic appeal. It is widely used for precision parts and decorative items. Brass has an ideal balance of strength, ductility, and conductivity, making it suitable for various industrial applications. Its versatile properties allow it to be used in applications from electrical connectors to mechanical components.
Composition and Features:
• Composition: Primarily composed of copper (Cu) and zinc (Zn), with small amounts of other metals like lead (Pb), tin (Sn), and arsenic (As) to improve its properties.
• Features:
• Good electrical conductivity
• High corrosion resistance
• Excellent machinability
• High strength and durability
• Attractive surface appearance, suitable for decorative parts
