Why Choose Magnesium?


Article Preview

The lightness of magnesium makes it an attractive material for applications where weight reduction is critical, in particular, consumer electronics and transportation industries. Despite its advantages as a material the use of magnesium worldwide is a tiny fraction of other materials (steel, plastic, aluminium). Amongst the reasons for this, the metal’s price has not been a significant factor until recently. Throughout the period of 2001-2006, magnesium has been cheaper than both aluminium and zinc on a volumetric basis. An issue that magnesium presently faces is a perceived insecurity of supply. 77% of primary magnesium is produced within China and the price has seen some enormous shifts. In late 2005 the magnesium price (primary FOB China) was about 1500USD/t. By the third quarter of 2008 it had risen to over 6000USD/t only to fall in recent month to below 3000USD/t. The current pricing levels of around 3000USD/t could prove beneficial if maintained over a long period, if it led to the establishment of new producers and a diversification of the supply base.
