Brass IS 319 Free Cutting Sheets & Plates

What are Brass IS 319 Free Cutting Sheets & Plates?

Brass IS 319 Free Cutting grade is a copper-zinc alloy specially designed for high-speed machining operations. It contains a small amount of lead, which enhances machinability and allows easy cutting, drilling, and shaping without compromising strength.

Key Functions:

• Provide excellent machinability
• Enable precision manufacturing
• Offer good strength and durability
• Ensure smooth surface finish in components

Chemical Composition of Brass IS 319 Free Cutting

Typical Composition:

• Copper (Cu): 57% – 61%
• Zinc (Zn): Balance
• Lead (Pb): 1.5% – 3.5%
• Iron (Fe): ≤ 0.5%

This composition improves cutting performance while maintaining strength and corrosion resistance.

Corrosion Resistance

Brass IS 319 sheets and plates offer good resistance to:

• Atmospheric corrosion
• Mild chemical environments
• Water and non-aggressive fluids
• General industrial environments

However, they are not recommended for highly corrosive or marine environments due to dezincification risks.

Heat Treatment

Brass IS 319 is generally not hardened by heat treatment.

Typical Process:

• Annealing for improved ductility

This helps in enhancing formability and workability.

Weldability

Brass IS 319 has limited weldability due to the presence of lead.

Welding Considerations:

• Brazing and soldering are preferred methods
• Avoid fusion welding where possible
• Ensure proper ventilation during processing
