Brass CZ121 Round Bar Rod - Diameters 8mm & 10mm x 300mm lengths ideal for model making (10mm Diameter)

Product Description

CZ121 Brass is an alpha/beta alloy that is very well suited for machining. This improved machining is due to lead that had been added to the Brasses composition. The added lead is insoluble in the Brasses' microstructure so the soft particles act as chip breakers. Brass is an alloy that is composed of Copper and Zinc. Different grades of Brass will also contain elements of other alloys that will provide different properties. Brass has a high tensile strength, high corrosion resistance and is suitable to be hot forged. Brass is separated into two types of class. Alpha alloys contain less than 37% Zinc in them, are ductile and can be cold worked. Alpha/beta alloys contain 37-45% Zinc and are both harder and stronger but are less cold ductility. Because of this CZ121 is also referred to as CZ121M to show its machining properties. CZ212 has good-excellent corrosion resistance. Cold working of CZ121 is not good and not recommended, although it can be knurled if needed.
