Stainless steel has the best corrosion resistance property. 

Stainless steel:

Due to its high chromium content, stainless steel forms a protective oxide layer on its surface when exposed to oxygen, significantly resisting corrosion. 

Aluminum steel:

While aluminum also forms a protective oxide layer, it is not as resistant to corrosion as stainless steel. 

Carbon steel:

Carbon steel lacks sufficient chromium and is highly susceptible to rusting.

22-karat gold, which contains 91.6% pure gold and 8.4% other metals like copper and silver,

It is commonly called "916 gold" or "22K gold" and is typically identified by a hallmark stamp indicating its purity. 

Explanation

Explanation

For example, 22-carat gold will be marked as "22K" or "916," representing 91.6% purity.

The 916 hallmark gold price is often higher due to this guaranteed purity.

Explanation

 18-karat gold contains 75% pure gold and 25% other metals, such as silver and copper. 

Explanation

Galvanized iron sheets have a coating of zinc. 

Galvanization is a process where a layer of zinc is applied to iron or steel to protect it from rusting, making "galvanized iron" essentially iron coated with zinc
