Silicon Metal

Most metallurgical silicon metal is used as an alloying agent in the aluminium industry due to its ability to increase the strength of aluminium. Demand from the aluminium industry has grown steadily in recent years due to increased usage of aluminium in structural engineering, aircraft manufacture and the automotive industry. Aluminium alloys are lighter and more resistant to corrosion than carbon-steel and can be made by addition of metals such as copper, zinc, magnesium, manganese as well as silicon.

Adding Silicon Metal to aluminium alloys makes them strong and light. As a result they are increasingly used in the automotive industry to replace heavier cast iron components. This allows weight reductions, a reduction in fuel consumption, increased efficiencies and subsequent benefits to the environment by reducing the greenhouse gas emissions and conserving fossil fuels.
