Free Cutting Brass is commonly known as leaded brass which contains 56 to 63 % of Copper, 2 to 3.50 % Lead, and balance Zinc. Free Machining Brass refers to the alloys "Machinability". Machinability is a catch term that measures the ease with which a metal can be drilled, turned, cut or machined. Free machining brass sets the standard by which the machinability of other alloys is measured. The usage of Free Cutting Brass ensures cost-effectiveness via the application of close-tolerance manufacturing techniques and reducing tooling costs. Apart from these benefits, the high value of this alloy's scrap can be used to reduce the production costs significantly.
IS 319 Free Cutting Grade I is the standard grade across the Indian Subcontinent for Free Machining Brass. It is widely used owing to its suitability for high-speed machining operations and also for the manufacturing of complex parts. The ease of brazing/soldering, high corrosion resistance combined with its good strength, and a machinability rating of 100% makes it an ideal choice of application in a wide range of brass components throughout the industry.
