The homogenous mixture of metals and non-metals results in the formation of an alloy. Alloys have properties that differ from the individual metals or non-metals they comprise of. They can have enhanced, or reduced, characteristics of the base metals and also have other unique properties. Alloys are used extensively in the production of various kinds of products.
The copper zinc nickel alloy is a copper and zinc alloy with a good combination of corrosion resistance, tensile strength and formability. It is suitable for deep drawing and can be forged, annealed and cold worked. This alloy is typically used in drawn cartridge cases, electrical springs and radiators.
It is not magnetic, and the reason is that its composition consists primarily of non-magnetic elements such as copper and zinc with traces of iron. Although it improves its strength and durability, the amount of iron does not affect its magnetic properties at all.
This article explains the chemical and physical properties of copper-nickel-zinc (nickelsilver) alloys, including its resistance to corrosion and tarnish. It is a useful reference for those looking to understand the properties of this material. It is also an interesting read for those interested in the history of copper alloys and their usage over time.
