About Molybdenum

Molybdenum has the sixth-highest melting point of any element. It is an essential trace element in biology, found in certain enzymes. It is primarily used in high-strength steel alloys.

Gebruiks & Programme

High-strength steel alloys, catalysts, lubricants (MoS2), missile and aircraft parts, and fertilizers.

Fun Fact

Molybdenum's name was confused for centuries with lead and graphite because they all left similar dark marks on paper.
