UNS C35330 Physical Properties
UNS C35330 has a density of 8.9 g/cm³ and a melting point of around 1100°C. It has good electrical conductivity and excellent thermal conductivity.
UNS C35330 Uses
UNS C35330 finds its application in various industries such as marine, aerospace, and automotive because of its excellent corrosion resistance and high strength. It is commonly used to manufacture propellers, valves, electrical connectors, heat exchangers, etc.
UNS C35330 Corrosion Resistance
UNS C35330 exhibits excellent corrosion resistance in seawater, freshwater, and mild acids environments. The alloy’s good corrosion resistance can be attributed to the presence of copper, which forms a protective oxide layer on the material’s surface.
UNS C35330 Heat Treatment
UNS C35330 has excellent heat resistance and can tolerate temperatures up to 300°C without losing its mechanical properties. The alloy can be annealed at 650°C to 720°C to improve its ductility and machinability.
UNS C35330 Machining
UNS C35330 is easily machined using conventional methods, and its good machinability is attributed to the presence of lead. However, the feed rate and cutting speed should be adjusted to avoid tool wear due to the material’s high tensile strength.
UNS C35330 Welding
UNS C35330 can be readily welded using TIG, MIG, and spot welding methods. However, care should be taken when welding this material as it is prone to cracking. Preheating the fabric to prevent thermal shock and the possibility of cracking is often necessary.
