Purifying the essential element for a stronger tomorrow







We are Magnium Australia

Magnium commercialises world-leading research from our national science agency to manufacture net zero carbon, zero toxin magnesium metal, deemed a critical mineral. The locally produced pure magnesium ingots (>99.8% purity per ASTM B92/B92M international standard) will drive the development of an advanced manufacturing supply chain and export industry and create jobs for regional Australians.

Magnium reduces dependence on foreign materials and ensures supply chain integrity by unlocking domestic supplies of feedstock.

The development of a large-scale magnesium plant will additionally support the growth of renewables, create hundred’s of advanced manufacturing jobs, and provide access to global export opportunities. Magnium anticipates the production of 100,000+ tonnes a year of magnesium metal from the company’s global operations by 2032. Magnium is primed to capitalise on its proprietary technology coupled with the rising demand for green critical minerals, driven in large part by their role in the transition to a low-carbon and digitized economy.

The Magnium process is the only independently validated, scalable alternate to the Pidgeon process, which today accounts for 87% of the world’s magnesium metal. The Pidgeon or silicothermic process is not viable short or long term given its negative impact on the environment and high amounts of carbon emissions. Magnium will take to scale new processes that engage low cost, low carbon energy supplies and highly efficient processes that reduce or eliminate toxic by-products to deliver globally competitive manufacturing of high-value metals.

Critical minerals are essential for renewable energy and clean technology applications (batteries, permanent magnets, solar panels, and wind turbines), they have also required inputs for advanced manufacturing supply chains, including defence and security technologies, consumer electronics, agriculture, medical applications, and critical infrastructure. Our national science agency has an exclusive relationship with Magnium to commercialise Magsonic, a globally patented technology. Our national science agency is an R&D collaborator in Magnium's project to build a net zero-emissions magnesium smelter in Australia.

About Magnesium Metal

As the eighth-most abundant metal in the universe and one of the lightest and most pliable metals used in alloy die casting and machining, magnesium has a wide range of uses and applications across many different industries. Of the structural metals, magnesium has the highest strength-to-weight ratio. The majority of use, 41%, is for alloying with aluminum to improve its strength, ductility, and corrosive resistance. 32% is for die casting applications such as electric vehicles, automotive components, power tools, mobile phone handsets, notebook computers, and others. 13% is for steel desulphurization, and the remaining 14% is for other uses in chemical processing including the processing of titanium.

Although too volatile, corrosive and combustible to be used in engineering applications by itself, pure magnesium can easily be combined with other metals, lightweight them, and moulded into almost any shape or texture. This creates the perfect compound material for thin-wall and complex structure formation and is a popular choice for projects that require intricate work.

Magnesium metal also offers an attractive cost-to-material ratio, making it a growth in-demand option for use in bulk machining or mass production.
