UNS C93200 Tin Bronze Chemical Properties, Grades, Table and Pdf

The C93200 Alloy, a type of bronze that is commonly known as Tin Bronze, is highly appreciated for its outstanding ability to machine as well as wear resistance. Copper along with tin and other elements like lead and zinc in small amounts are what in essence comprises this alloy. This sorts of the metal demonstrates superior strength and corrosion resistance which are quite useful in such applications as bearings, bushings and gears. The grades of UNS C93200 are based on the desired compositions and mechanical properties for the various applications. A chemical composition which can be called a typical one, contains about 83% of copper, 7-10% tin and small amounts of other metals too. Their properties are usually represented in the form of tables with the strength, thermal conductivity, and corrosion resistance parameters. All the necessary details and specifications about the UNS C93200 Tin Bronze are included in the tables, chart and PDF documents provided by the material suppliers and the industry standards organizations.

UNS C93200 Tin Bronze Chemical Composition And Grade Table

UNS C93200, commonly called Tin Bronze, is a copper alloy with a high tin content within the range of 7.5% to 9.5% by weight. Copper-tin base may be supplemented by the minor additions of elements like zinc, lead, and silicon into the alloy. Those elements exert influence on its mechanical and chemical properties. Such mechanical characteristic as high hardness in all areas, very good machinability, corrosion resistance and good thermal conductivity, make the alloy very usable for all kind of applications like bearings, bushings and gears. UNS C93200 Tin Bronze with balanced chemical formulation and grading standards promises consistent performance for different industries and maintains acceptable levels of quality to meet the strict qualification standards.

The Advantages and Disadvantages of UNS C93200 Copper Material Properties, C93200 Properties

    Advantages:

  • Good Bearing Properties: C93200 copper offers high bearing capabilities hence ideal for bushing, bearings and other similar uses.

  • High Wear Resistance:strong> Provides better abrasion properties because of the incorporation of lead resulting to service life of component used in extreme environments.

  • Self-Lubricating: The lead content offers natural lubricity, thus minimising friction and wear in applications where no extra lubrication is used.

  • Corrosion Resistance: Exhibits high levels of corrosion resistance in different conditions making it suitable for use in marine and industrial fields.

  • Machinability: Moreover, C93200 copper is easily machinable, thereby enabling the manufacturing of complex shapes where high accuracy is required.

    Disadvantages:

  • Lead Content: It contains lead which is a threat to the environment and human health hence must be handled carefully and dispose of appropriately.

  • Limited Weldability:It is relatively difficult to weld C93200 copper due to various techniques that have to be employed to prevent problems like, hot cracking and porosity.

  • Cost: Copper alloys such as C93200 might be more costly compared to other materials and hence influence the overall cost of a project.

  • Potential for Dezincification: It is sensitive to dezincification in very aggressive services environments hence the need to be very selective on material and meticulous on the maintenance carried out on it.

  • Availability: Availability of stock shapes or standard forms of C93200 copper may be somewhat restricted as compared to more generic copper alloys.
