UNS# C86400

Leaded Manganese Bronze C86400 (Bronze CDA 86400), also known as Leaded High Strength Yellow Brass, is a cast Copper alloy that is made of Copper and Zinc, with Aluminum, Lead, Tin, Iron, Manganese and Nickel & Cobalt. This cast bronze is primarily used in roller bearing applications.


High Strength Yellow Brass C86400 (CuZn40Fe2AlMnPb) is an alpha-beta brass with additions of 2% Fe and 1% additions of aluminium, lead and manganese. The iron, aluminum, and manganese, provides additional strength and corrosion resistance, while the lead is added to increase the machinability.


The alloy has good wear resistance and is used for roller bearing cages where the properties of high strength, ductility, good fatigue, excellent bearing, and excellent machinability make it a popular choice.


When used as a shaft bearing, the shaft needs to harden.


Welding techniques for High Strength Yellow Brass are soldering and brazing. Carbon arc welding, oxyacetylene welding, gas-shielded arc, and coated metal arc welding are not recommended for this alloy.


C86400 has a machining index of 65% when compared with free machining brass at 100%.


The Bronze CDA 86400, offered by Wieland Diversified, is a testament to their commitment to manufacturing products of the highest quality. This alpha-beta brass alloy exhibits remarkable properties that make it a top choice among industries that need robust and reliable bronze components.


One of the distinctive advantages of using Bronze CDA 86400 is its superior wear resistance. This attribute is crucial in applications involving significant friction, such as roller-bearing cages.


By eliminating the rapid wear and tear common in such settings, this bronze alloy significantly extends the product life cycle, thereby enhancing operational efficiency and reducing maintenance costs.


Furthermore, the alloy’s excellent bearing and fatigue properties, combined with its high strength and ductility, make it highly versatile.


These attributes allow CDA metals to be utilized in various applications, from construction and industrial equipment to automobile components. Therefore, this material offers a comprehensive solution for various industries.


As for machinability, high-strength yellow brass scores 65 percent on the machining index, making it a highly machinable material. This means that it can be easily shaped, cut, or drilled, making it a preferred choice for intricate and precise applications.
