QMG buys magnesium on the spot market then melts it down and mixes it with a small amount of aluminium to form a magnesium alloy which is mainly used as you mention for automobile castings.
Their initial problem was the magnesium got to expensive for them to buy as a raw material compared with the price they were selling the alloy for.
They have been trying to go in partenrship with a magnesium supplier to reduce their raw material cost.
They are not the only producer of alloy (most now are chineese producers who seem to have a lower cost structure than QMG)
QMG alloy seems to have less imperfections than other magnesioum producers and it is certified.
Its a risky stock as you will find out by reading the auditors report in the annual report. But then it has the potential for high reward (but too risky for me)
