CuZn36Pb3<\/strong> is a brass alloy<\/strong> consisting of copper (Cu)<\/strong>, zinc (Zn)<\/strong>, \u0e41\u0e25\u0e30 lead (Pb)<\/strong>. It typically contains around 36% zinc<\/strong> and 3% lead<\/strong>, which gives it unique properties such as excellent machinability<\/strong> and good corrosion<\/a> resistance<\/strong>. This alloy is commonly referred to as Leaded Brass<\/strong> because of the addition of lead, which improves its machinability by acting as a lubricant during the cutting process.
