– Nickel is a common and inexpensive white metal used in white gold alloys, especially in the United States. It provides hardness but can cause allergic reactions in some individuals.
– Palladium is a more expensive white metal used in white gold alloys, particularly in Europe. It produces a whiter alloy and is hypoallergenic.
– Platinum is also a white metal and can be used, often as part of a platinum group metal mix including palladium.
– Silver is a white metal sometimes used in smaller quantities to modify color and workability.
Option A lists gold, nickel, and palladium, which are all standard components found in various white gold alloys.
Option B lists cobalt, which is less commonly used than nickel or palladium in standard white gold jewelry alloys.
Option C lists titanium, which is not typically used in gold alloys for jewelry purposes.
Option D lists magnesium, which is also not typically used in gold alloys for jewelry purposes.
Therefore, gold, nickel, and palladium represent a typical composition of white gold alloys.
– Common white metals alloyed with gold include nickel, palladium, silver, and platinum.
– Option A correctly lists common alloying metals for white gold.
