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 %

Stainless Steel Hexagon Bar 316/316L is a hexagonal shaped 316/316L Stainless Steel Alloy bar. 316 Stainless Steel Alloy is a standard molybdenum-bearing grade, the second most commonly sought after grade next to grade 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance in chloride environments. Grade 316L (L= low carbon) ) is the same as 316 except it has an extra-low-carbon analysis, the advantage of which is that it precludes any harmful precipitation in the 800º F to 1500º F range that might result from welding heavier sections. Therefore 316L is extensively used in heavy gauge welded components. Typically there is no price difference between 316 and 316L stainless steel.
