UNS C68700 Copper Alloy Chemical Composition & Properties, Grades, Tables and Pdf

UNS C68700 is a typical copper alloy applied worldwide as a good material for stationary objects placed in corrosive salts with high moisture degree. This alloy has copper as its primary component together with zinc and aluminum. It shows considerable resistance to warping and wearing under strain. Copper, being an alloy, it is usually 76%-79% copper while 0.5%-1% of aluminum and up to 0.5% iron exist and then other unspecified minerals that could be up to 0.5%. C68700 is the most commonly used and is made from ceramic-based high-performance material that is corrosion and biofouling resistant for marine and in-shore infrastructures. In order to prevent environmental degradation, the maritime waste management systems uses both active and passive inception including through the condensers, heat exchangers and other water handling processes. This material is known for high thermal conductivity and mechanical performance, so it is a bit different from its counterparts and works effectively even in rough conditions. Grades and specifications are broadly used to help clients select products uniquely suitable for their facilities and applications. The chemical composition, mechanical properties and grade classifications are depicted by the use of tables and PDF documents for the purpose of reference.

UNS C68700 Copper Alloy Chemical Composition And Grade Table

Copper alloy UNS C68700 is frequently referred to as aluminum brass in the marine environmental system as it is known for its abrasion-resistance attributes. It is basically made up of copper (Cu), which in normal case comprises by 76-79% of copper and 2.8-3.5% of aluminum (Al) and trifling amount of still some other elements, such as zinc (Zn) and manganese (Mn). Heat transfer is the highlight of this alloy and it is frequently used in condensers, heat exchangers, condenser tubes and similar marine applications. On this basis the chemical balance compositions are in line C68700 offers strength and ductility at the same time that is conducive to industries with the need to withstand sea corrosion.

  • High strength: It has good tensile and yield strength, which implies structural integrity and durability in demanding applications.

  • Good thermal conductivity: The alloy has excellent thermal conductivity, which makes it the ideal material for the heat transfer applications, such as heat exchangers and HVAC systems.

  • Biostatic properties: Copper alloys such as UNS C68700 have the antimicrobial properties that are the reason why they are used for medical and food processing equipment because they can inhibit the growth of bacteria and fungi on their surfaces.

  • Ease of fabrication: It is quite easy to fabricate, which results in the efficient production processes and cost-effective manufacturing of the complex components.

    Disadvantages:

  • Cost: UNS C68700 copper alloy can be more expensive than other copper alloys or other materials, which can affect its affordability for some applications.

  • Limited availability: Depending on the region or supplier, UNS C68700 may have limited availability, thus, the lead times or procurement costs may be higher or the period to get it may be longer.

  • Potential for dezincification: Similar to most brass alloys, UNS C68700 is prone to dezincification in some environments, which can weaken its mechanical properties and structural integrity.

  • Aluminum content: The aluminum in UNS C68700 may influence its weldability and solderability, thus it will need special techniques and procedures for joining.

  • Surface tarnishing: Although it has good corrosion resistance, UNS C68700 may tarnish over time, especially in outdoor environments with the exposure to pollutants, thus, periodic maintenance is required to keep its appearance.
