UNS C64200 Silicon-Aluminium Bronze Chemical Properties, Grade, Chart and Document

UNS C64200 is the common type of Aluminium Silicon Bronze Alloy that has successfully achieved optimum corrosion resistance in sea-water and acidic solutions. The alloy compound of these significant elements it is known to have general properties that it can be used as a replacement for the manufacturer’s parts such as propellers, pump parts, and valves. It gets the mark of replacing a conventional improved bronze alloy with a Grade B, which indicates that it will be more robust than that of any currently used brass in the industry. Usually, the chemical properties table containing the amount of copper (Cu) which can be 79-83% and 3.0-4.9% is the amount of silicon (Si), 8.5-11.0% is the amount of aluminum (Al) and 2.0-3.5% is the amount of iron (Fe). In addition, the maximum amount of manganese (Mn) is 2.0%. Manufacturers offer all technical data and mechanical and corrosion resistance reports, therefore, confirming the suitability for industrial and marine applications meeting the most demanding environmental conditions and operating in extreme conditions.

UNS C64200 Silicon-Aluminium Bronze Chemical Composition And Grade Table

UNS C64200 is a high-reputed metal with corrosion rate and low corrosion rate, therefore having great reliability and durability. Its chemical composition which is normally made of 83% to 85% copper, 2.8% to 3.8% aluminum, 5% to 6.5% silicon, 3.0% iron and 0.05% max lead, it has trace amounts of other elements. This composition is what has seen it widely bear within the marine communities for the fact that it withstands what saltwater corrode as well as erode. It is often used in marine equipment, valves, pumps, and other components that have to withstand hydraulic pressure or are prone to corrosion. The special properties give it the ability to be used in the hardest of the engineering projects.

  • Good Corrosion Resistance: It provides well the resistance to corrosion in various environments such as marine and industrial areas, which makes it the right choice for the applications exposed to moisture and chemicals.

  • High Thermal Conductivity: Copper C64200 has the perfect thermal conductivity, which is why it is used in the applications like heat exchangers and electrical conductors because of the efficient heat transfer.

  • High Electrical Conductivity: It is a great electrical conductor, thus making it the ideal material for electrical and electronic applications in which conductivity is the key factor.

  • Versatility: UNS C64200 Copper is the most versatile and can be applied in many areas, including plumbing fixtures, valves, fittings, and electrical components.

    Disadvantages:

  • Low Strength: The UNS C64200 Copper, in comparison to some other copper alloys, has a low strength, which may be a limiting factor in its use in applications that need high mechanical strength.

  • Susceptibility to Dezincification: Like other brass alloys, C64200 Copper is vulnerable to dezincification, a type of corrosion that can take place in certain hostile conditions and thus, the integrity of the alloy may be affected.

  • Cost: Copper, for example UNS C64200, is often more expensive than other materials and this, in turn, may affect the total price of projects or products where it is used.

  • Softness: C64200 Copper is soft, which could result in deformation or broken due to the high loads or mechanical stress in the applications.

  • Limited Temperature Range: Albeit the thermal conductivity of copper is excellent, its mechanical properties are liable to be weakened at high temperatures, thus, making it not fit for high-temperature applications.
