1. Chromium (Cr)

A hard and shiny metal, chrome is often used in stainless steel. Because it has a high melting point, it is used to make brick molds. And because it is shiny, it is used in the manufacture of stains and paints – when applied to other metals, it is often referred to simply as chrome.

2. Zinc (Zn)

A non-corrosive metal, zinc has many applications: it is used in paints, rubbers, cosmetics, batteries, textiles and ink production. Even our bodies need zinc – its deficiency was recognized as a clinical health problem in 1961. Zinc is essential for cell growth, fertility, immunity, healthy skin and vision.

3. Palladium (Pd)

Another hard, non-corrosive metal, palladium readily absorbs hydrogen. It is used as a catalyst and is an integral part of jewelry making – along with gold and certain alloys, like nickel and silver, it is used to create a mixture called white gold. It is used in watch bearings, springs, and in most electrical devices, such as televisions and cell phones.

4. Antimony (Sb)

This brittle metalloid was used by the ancient Egyptians as a black kohl or eye makeup. Today, the element is used to make flame retardant materials and paints, which is why it is an effective part of cable and battery sheathing.

5. Osmium (Os)

With a high melting point, osmium is a hard, non-corrosive metal and it is the densest element in existence. You can find it in the tips of ballpoint pens, recording needles, electrical contacts, and other metal parts where friction needs to be reduced.
