Brass Hexagon Bar CZ121 is a hexagonal shaped CZ121 Brass Alloy bar. CZ121 Brass Alloy is a free-machining brass consisting of a duplex phase structure with a 3% lead content. It is suited to high speed machining operations due its superior machinability, thread rolling and knurling characteristics. Particles of lead are finely dispersed throughout the microstructure, acting as both a lubricant and a chip breaker to give the alloy its free-machining characteristics. CZ121 Brass Alloy’s machinability rating of 100 is the standard against which all copper alloys are rated. It offers good strength, is easily soldered or brazed and has good resistance to corrosion. • Specifications CZ121 (CW614N) Free Machining Brass • Characteristics o Corrosion Resistance: Excellent o Cold Working: Poor o Hot Working: Excellent o Heat Treatment: Good o Machinability: Excellent o Weldability: Excellent • Uses Common uses of Brass Hexagon Bar CZ121 include: o High Speed Machined Components o Architectural Extrusions o Locks o Hinges • More Info o Density = 8.47 g/cm³ o Melting Point = 875 °C o Thermal Expansion = 20.9 x10^-6 /K o Modulus of Elasticity = 97 GPa o Thermal Conductivity = 123 W/m.K o Electrical Resistivity = 0.062 x10^-6 Ω .m o Proof Stress = 220 - 350 MPa o Tensile Strength = 360 - 500 MPa o Hardness Brinell = 90 - 160 HB o Elongation A = 20 - 5 %
