UNS C35330 vs C35330 Alloys – What’s the Difference

UNS C35330 vs C35330 Alloys

Copper alloys are integral in various industries, including plumbing, marine, aerospace, and engineering, to mention a few. UNS C35330 and C35330 are some of the most commonly used copper alloys. However, what sets them apart? This article will discuss the differences between the two alloys to help you make an informed decision.

Difference UNS C35330 and C35330 Alloys

Composition

C35330 alloy is a nickel-silver alloy with 62.5% copper, 12.0% nickel, and 25.5% zinc. This composition gives the alloy excellent corrosion resistance, making it ideal for marine and plumbing applications. UNS C35330, on the other hand, is a leaded nickel-silver alloy that contains 60% copper, 20% nickel, and 20% zinc. The lead content in UNS C35330 increases machinability but compromises the alloy’s corrosion resistance.

Strength and Ductility

UNS C35330 is stronger and less pliable than C35330 alloys. Adding lead to the UNS C35330 alloy improves its machinability but comes at the expense of reduced ductility and strength. As such, C35330 is more suitable for industrial and commercial applications that require stronger materials than UNS C35330.

Uses

Both UNS C35330 and C35330 alloys have a wide range of applications. UNS C35330 is ideal for manufacturing gears, bearings, and other intricate parts that require complex machining. Its lead content makes it ideal for turning and drilling, while its strength makes it ideal for high-stress applications. On the other hand, C35330 alloy is commonly used in applications that require high corrosion resistance and flexibility. It is ideal for plumbing fixtures, marine hardware, and electrical components.

Machinability

UNS C35330 has better machining properties than C35330 alloys. Its lead content makes it more machinable and gives it a higher percentage rating on the machinability index. C35330, on the other hand, requires lubrication to reduce its friction coefficient, which increases the amount of force required to machine it.

Price

UNS C35330 is more expensive than C35330 alloys. This is because of its higher nickel content, which gives it better corrosion resistance and machinability. UNS C35330’s lead content also adds to its cost, making it relatively expensive compared to C35330 alloys.

Conclusion

In summary, UNS C35330 and C35330 alloys are copper but differ in composition, strength, flexibility, uses, machinability, and price. Understanding these differences is crucial in selecting the appropriate alloy for your application. C35330 is ideal for applications requiring high corrosion resistance and ductility, while UNS C35330 is an excellent choice for complex machining applications. Ultimately, deciding which alloy to use depends on your needs, budget, and availability.
