Our Magnesium Thesis

Estes has been quietly innovating across all aspects of this incredible material: flame retardant alloys, an automotive scale forming process, and a multi-layer coating.  Together, Estes is building a domestic manufacturing capability for large format magnesium components - built in the USA.

Manufacturing

Manufacturing

From Levius™ to Giga-Thixomolding

Estes' patent-pending Levius™ process unites alloying, forming, and coating in a single continuous production line, producing flame-retardant, thin-walled, corrosion-resistant magnesium components for lightweight power systems in defense, space, aerial, marine, and commercial applications.

Giga-Thixomolding forms 30kg of MgCarbonit™ in a single shot at a rate of one part-per-minute.

Systems

Cell-to-pack

Magnus uses today's commercially available cells. What’s different is everything built around them. The thermo-structural body is cast from MgCarbonit, Estes’ proprietary magnesium alloy: structural, non-flammable, and a third lighter than aluminum. The result is energy density of 225 Wh/kg delivered from a platform that no conventional pack architecture can match.

Cell-to-X

The best part is no part. Estes' alloying, forming, and coating capability enables building the machine around — and from — the battery system. Passive and active thermal management strategies can be fully integrated into cell-to-airframe and cell-to-machine architectures, eliminating mass and cost from high-performance systems.
