Above 38 °C, it transforms into a paramagnetic state. •Chromium is an essential trace element for humans because it helps us to use glucose. However, it is poisonous in excess. We take into our bodies about 1 milligram a day.  •Chromium, unlike metals such as iron and nickel, does not suffer from hydrogen embrittlement.  •Chromium is the 21st most abundant element in the Earth's crust. •Chromium in air is passivated by oxygen, forming a protective layer that is essentially a spinel that is a few atoms thick •This is high quality yet cheap affordable Chromium •Safety / Caution  •Keep out of reach from children! •Do not ingest Chromium.
