BRASS

C330 Brass
Normally only available in tubing products, it has a good balance of workability and,
because of the presence of lead, machinability.
Applications: Industrial: Power and Pump Cylinder Liners, Power and Pump Cylinders;
Ordnance: Primers. Plumbing: plumbing accessories, pump lines, trap lines,
j bends, plumbing brass goods.
Analysis: Cu - 66% Zn - 33.5% Fe - .07% Pb - .5%
Common Fabrication Processes: Forming and bending, machining, piercing and punching.
Mechanical Properties: (room temperature, 68º F (20ºC)
Ultimate Tensile Strength (psi) 65,300
Yield Strength (psi) 50,000
Elongation (%) 32
Rockwell Hardness B80
Machinability: Machinability rating is 60. Hot Forming: Poor. Cold Working: Excellent.
Joining Techniques: Excellent for: Soldering. Good for: Brazing; Fair for: Oxyacetylene, gas shield arc, spot and butt welding.; Not Recommended for: Coated metal arc and seam welding.
C360 Brass
The most commonly used of the brass rod and bar items. The presence of lead creates
a highly machinable material that can be cut, drilled and shaped easily.
Applications: Architecture: Terrazzo strip; Automotive: Sensor bodies, thermostat parts, fluid connectors, threaded inserts for plastic; Builders Hardware: lock bodies, fittings, hardware; Consumer: hot combs (to straighten hair); Fasteners: screws, nuts, bolts; Industrial: faucet components, pinions, automatic screw machine parts, pneumatic fittings, gears, nozzles, valve stems, valve trim, valve seats, gauges, fluid connectors, screw
machine products, adapters, unions; Plumbing: faucet stems, plumbers’ brass goods, faucet seats, plumbing fittings.
Analysis: Cu - 60/63% Zn - 35.5% Fe - .35% Min. Pb - 2.5-3.7%
Common Fabrication Processes: Machining, roll threading and knurling;
Mechanical Properties: (room temperature, 68º F (20ºC)
Ultimate Tensile Strength (psi) 58,000
Yield Strength (psi) 45,000
Elongation (%) 25
Rockwell Hardness B78
Machinability: Machinability rating is 100. No material of comparable strength machines faster and produces better surface finishes than C360. Hot Forming: Fair. Cold Working: Fair. Corrosion Resistance: Excellent. Joining Techniques: Excellent for: Soldering. Good for: Brazing; Fair for: Butt weld; Not Recommended for: Oxyacetylene, gas shield arc welding, coated metal arc, spot, and seam welding.
