Explain what the alloy is made of and the percentages of each material
White Gold: 75% fine gold, 10 % copper, 8% nickel, 4.5% zinc, and 2.5% silver.
Explain how the alloy was manufactured
White gold is manufactured by alloying other metals with yellow gold. Most commercial alloys are zinc, silver, gold and nickel however platinum is also used. White gold is available only up to 21 carat so as to retain the white color.
Three physical and chemical properties for the alloy
1. It's a dense metal
2. It melts at 1065 degrees
3. It is a good electrical conductor.
Three Chemical properties of white gold are:
1. It's chemical formula is Au
2. It is chemically inactive and resistant to chemical action.
3. It does not react with other Non-metals.
