How can you make yellow gold to white gold?

Answer 1

If you mix it with 50% silver you'll get electrum which is a natural alloy of gold.

This is not white gold as it has a yellow tinge and would need constant rhodium plating.

There are several combinations to make white gold some include zinc,nickel and silver depending on the carat-age of the gold you want.

The best combination to make white gold is:

For 18ct white gold- 75% gold and 25% palladium

For 9ct white gold- 37.5% gold and 62.5 palladium

Palladium is a high density transition metal of the platinum group.

Not quite as dense as platinum, palladium is by far the best metal to use to make a white gold alloy.It has a high white luster and is relatively cheap compared to gold.

The only major problem with palladium is the high melting temperature which is around 1700 degrees celsius this, when alloyed with gold (1063 degrees) will bring the total temp around 1400 degrees celsius.

In my opinion there simply should not be a white gold as palladium is cheap and

much whiter than white gold which means you can avoid constant rhodium plating.

Answer 2

To change yellow gold into white gold, the yellow gold must be alloyed with white metals such as nickel, palladium, or silver. The resulting alloy will have a white color similar to white gold. Note that this process should be done by a professional jeweler to ensure the correct proportions and quality of the white gold alloy.
