Standard Specification for Aluminum Bronze Rod, Bar, and Shapes
This specification establishes the requirements for rods, bars, and shapes of aluminum bronze with Copper Alloy UNS Nos. C61300, C61400, C61900, C62300, C62400, C63000, C63020, C63200, C64200, and C64210. Products shall be produced in tempers HR50, M10, M20, M30, O20, O25, O30, O32, TQ30, TQ50 and TQ55. Products shall be tested and shall conform to dimensional (mass, diameter, length, thickness, straightness, and edge contour), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements. Products should also meet requirements under the mercurous nitrate test, ammonia test, and piston finish.

C61400, C62400, and C63020 belong to the aluminum bronze family, providing excellent corrosion resistance. C61400 contains 4-6% aluminum, while C62400 and C63020 contain 6-9% aluminum. These materials exhibit high strength, good thermal conductivity, and are easily machinable. Widely used in marine environments, they serve as propellers, bearings, and valve components due to their excellent resistance to saltwater corrosion and wear resistance.

C10100, C10200, and C10300 belong to the oxygen-free copper family, characterized by their high electrical conductivity. C10100, also known as Oxygen-Free Electronic (OFE) copper, has a minimum of 99.99% copper content. C10200 and C10300 have slightly lower copper content but still offer exceptional electrical conductivity. These materials find applications in electrical and electronic industries, particularly for power transmission, transformer windings, and electrical contacts, where conductivity is crucial.

Copper Profiles
Copper profiles are commonly used in distribution panels and switchboards delivering key electrical advantages. Profiles are more expensive and difficult to manufacture than flat bars due to the technical requirements such as they provide a more fragile production process, more complicated packaging, and a complex design. Although the profile offers a more detailed process, its unique design enables the manufacturer to meet the demands of individual projects.
Typically, Copper profiles are used in power and electrical engineering, onshore and offshore wind power, mechanical engineering, and supply equipment. Copper profiles are an effective way to reduce the weight of Copper conductors in an existing product. Profiles also allow for flexible designing and can meet the requirements for exact designs in individual jobs. Profiles can be designed to allow fast, hole-free assembly and jointing, which can significantly reduce the time required to assemble bars in a cabinet, improving consistency and quality. Due to the increased surface area of the Copper, the profile can assist in the heat dispersion as the larger shapes and sizes increase the conductivity.
