Platinum is malleable if alloyed with gold
Certian types of low karat gold may be alloyed with semi-precious metals such as silver, copper, iron or staimless steel. Also, white gold is sometimes alloyed with silver. The higher the karat of the gold, the less likely that it was alloyed with silver.
Platinum Jewlery is a much more expensive and high quality type of jewelry than gold jewerly. Although many see gold as the best type of jewelry it is in fact platinum that wins the title.gold can react with mercury but platinum canot that was the extra quality of platinum
Like gold, platinum is very resistant to corrosion. However, platinum is much harder than gold so it does not get scratched or dented as easily.
No. Neither gold nor platinum will oxidize except under extreme conditions such as immersion in aqua regia.

Historically gold and silver, but also copper, platinum, and various alloys such as pewter. Silver and gold are most often alloyed with base metals to improve hardness and decrease costs.
In chemistry, solid gold is a metallic element. In jewelry, gold may be alloyed with other metals, such as silver: and some "gold jewelry is simply gold-plated.
Silver and Gold are not necessarily nickel-free, in 9 carat gold there isn't actually that much gold! The gold in jewelry is alloyed with other metals - and it is crucial to find out what those other metals are. Look for "guaranteed 100% nickel-free". Find a supplier/retailer who caters to and understands this need. Many don't! Addition: Palladium and Platinum jewelry are nickel free. 950 Platinum is 95% pure Platinum and 5% of either Iridium or Ruthenium (all part of the Platinum family). Palladium is also part of the Platinum family, but much lighter and less expensive than Platinum. Only a small handful of jewelry designers, like myself, create jewelry using Palladium mixed with 24K Gold to yield a 18K Palladium combination.
