Brass Rounds

Brass Rounds

Brass round bars are cylindrical rods made from brass, an alloy primarily composed of copper and zinc. They offer good machinability, corrosion resistance, and electrical conductivity. These bars come in various diameters and lengths, making them ideal for a range of industrial and decorative applications.

Common Grades of Brass Rounds:

  • C360 (Free-Machining Brass): High machinability, corrosion resistance, and strength, making it ideal for precision components.
  • C464 (Naval Brass): High corrosion resistance, particularly in marine environments.
  • C260 (Cartridge Brass): Good ductility and strength, commonly used in ammunition casings and decorative applications.

Applications:

  • Precision machining
  • Plumbing and fittings
  • Automotive and aerospace parts
  • Electrical connectors and terminals
  • Decorative and architectural elements

Precision Ground Brass Bars

Precision ground brass bars are brass rods that have been ground to tight tolerances for enhanced dimensional accuracy and surface finish. They are used in applications where high precision is required, such as in bearings, shafts, and precision components.

Key Features:

  • Tight dimensional tolerances: Ensures consistent sizing for precise applications.
  • Smooth surface finish: Reduces friction and improves aesthetics.
  • Superior straightness: Ideal for shafts and linear motion systems.

Common Uses:

  • Precision instruments
  • Hydraulic and pneumatic systems
  • Aerospace and medical components
  • High-performance mechanical assemblies
Brass rounds (cylindrical brass stock) come in various grades, each with different compositions and properties suited for specific applications. Here are some of the most common brass grades used for rounds:

Common Brass Grades for Rounds

C260 (Cartridge Brass)

  • Composition: ~70% Copper, ~30% Zinc
  • Properties: High strength, good corrosion resistance, excellent cold working properties
  • Uses: Ammunition casings, plumbing fittings, automotive radiator cores, fasteners

C360 (Free Machining Brass)

  • Composition: ~61.5% Copper, ~35.5% Zinc, ~3% Lead
  • Properties: Excellent machinability, good corrosion resistance, moderate strength
  • Uses: Precision components, valves, fittings, and fasteners

C464 (Naval Brass)

  • Composition: ~60% Copper, ~39% Zinc, ~1% Tin
  • Properties: High corrosion resistance (especially in marine environments), strong and durable
  • Uses: Marine hardware, propellers, shipbuilding components, heat exchangers

C220 (Commercial Bronze)

  • Composition: ~90% Copper, ~10% Zinc
  • Properties: Good strength, corrosion resistance, and a reddish-gold color
  • Uses: Decorative applications, jewelry, medallions, and light mechanical parts

C230 (Red Brass)

  • Composition: ~85% Copper, ~15% Zinc
  • Properties: Strong corrosion resistance, good machinability, and good forming properties
  • Uses: Plumbing pipes, electrical connectors, and musical instruments

C280 (Muntz Metal)

  • Composition: ~60% Copper, ~40% Zinc
  • Properties: High corrosion resistance, stronger than pure brass
  • Uses: Architectural trim, marine applications, industrial machinery

C385 (Architectural Bronze)

  • Composition: ~57% Copper, ~40% Zinc, ~3% Lead
  • Properties: Excellent machinability, high strength, good corrosion resistance
  • Uses: Architectural hardware, decorative elements, and structural applications

Choosing the Right Brass Grade

  • If you need excellent machinability: C360
  • If you need high corrosion resistance (marine use): C464
  • If you need high strength and cold workability: C260
  • If you need an aesthetically pleasing alloy: C220 or C230
  • If you need a mix of machinability and corrosion resistance: C385
