Machining Brass Round Square Rectangular Bar/Rod Angle & Tube 50mm - 600mm Long

This material is brilliant for milling, turning and drilling purposes. Perfect for the model engineer and machinist.

This material is the most widely used of all the brasses due to its suitability for high speed machining operations and also the manufacture of intricate parts. Its combination of machinability, thread rolling and knurling characteristics, combined with its good strength, an ease of soldering / brazing and a high resistance to corrosion makes it the ideal choice for many brass components throughout industry.

Available in lengths of 50, 100, 150, 200, 305 and 600mm Lengths cut to a tolerance of +/- 2mm  
Stock Metal Tolerances Apply - +/-0.2mm on other dimensions Please note that this is a "rule of thumb" and often dimensions are well within this tolerance.

Material Information

Brass is an alloy that is comprised 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.

CZ121

CZ121 is the standard European grade of free-machining brass consisting of a duplex structure and a 3% lead addition. The particles of lead are finely dispersed throughout the microstructure and acts as both a lubricant and a chip breaker to give the alloy its free machining characteristics.

The machinability rating of 100% for CZ121 is the standard against which all other copper alloys are rated. It is the most widely used of all the brasses due to its suitability for high speed machining operations and also the manufacture of intricate parts. Its combination of machinability, thread rolling and knurling characteristics, combined with its good strength, an ease of soldering / brazing and a high resistance to corrosion makes it the ideal choice for many brass components throughout industry.

Typical Uses:

Traditional uses for CZ121 include a wide variety of machined components made on high speed lathes including screws, bolts, nuts, bushing, pins, washers, butts, hinges and also locks and components for watches. This grade is particularly suited to machining
