Aluminum cannot be produced without magnesium - Magnesium Supply Dries Up

This week, the largest US producer of aluminum billet used to make automobiles and building supplies told customers and business associates that output capacity might be curtailed in 2022 due to a lack of magnesium supply.

"In the last several weeks, magnesium availability has dried up, and we have not been able to purchase our required magnesium units for all of 2022," Matalco Inc. President Tom Horter said in the letter obtained by S&P Global Platts.

Difficult-to-source supplies of raw materials and soaring energy prices are adding to the headwinds, Horter said in the letter.

"The purpose of this note is to provide this advanced warning that, if the scarcity continues, and especially if it becomes worse, Matalco may need to curtail production in 2022, resulting in allocations to our customers," he said.
