BGS Risk List (5)


Last week saw us looking at our element in position number 6; strontium. This week we can safely say we’re halfway through our countdown, and the lucky element that gets to share that landmark with us is…molybdenum!


RANKING:
5

ELEMENT NAME AND SYMBOL:
Molybdenum (Mo)

RELATIVE SUPPLY RISK INDEX:
8.6

WHY?:
The main reason for Mo’s risk is an economical one. As will be apparent below, it is mostly used in alloys for stainless steel pans amongst other items. Many countries are facing recessions and as people stop spending money on kitchenware the value of molybdenum is decreasing. Subsequently producers are focusing their efforts on our more valuable metals often found alongside molybdenum, for example copper, and so the supplies of Mo are decreasing.

LEADING PRODUCER:
China

TOP RESERVE HOLDER:
China

WHY THE DEMAND?:
Molybdenum has the sixth-highest melting point of any element, is extremely hard and will readily form chemical bonds with other elements. Therefore it is extensively used in various steel alloys, including superalloys; in fact 80% of Mo produced is used in these processes.

The remaining 20% is used in fertilizers (particularly for cauliflowers!) and in the mechanism for mammograms, amongst other applications.
