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, a domestic manufacturing capability for high-voltage battery systems – and beyond – built in the USA.

01

Alloy: MgCarbonit™

Estes’ proprietary magnesium alloy: 33% lighter than aluminum, thermally conductive, flame retardant. Two formulations: MgCarbonit60 (high ductility) and MgCarbonit91 (high strength). Recyclable. 3rd party tested to FAA safety standards.

02

Forming: Giga-Thixomolding

Estes’ thixomolding press is a fully-electric light metal casting machine capable of producing some of the largest magnesium components in the world. Raw materials in, thermo-structural frames out.  Up to 30kg of MgCarbonit material can be molded at one shot-per-minute.

Coating: Levius™

For all its benefits, magnesium corrodes. Estes’ proprietary Levius coating morphs magnesium surfaces into stable oxide ceramic, unlocking our ability to use MgCarbonit as a thermo-structural element in high voltage systems exposed to brutal environments.

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.

Frequently asked questions.

Can't find the answer you're looking for? We're here to help.

What is the Levius Process?

Estes' proprietary Levius™ process is an end-to-end manufacturing and coating process for magnesium components. It integrates three steps: Estes' flame retardant MgCarbonit™ alloy mixing process, giga-thixomolding, and application of a multi-layer, protective coating that unlocks magnesium for high-voltage cell-to-pack battery architectures. Estes is growing its portfolio of patents pending and trade secrets which cover Levius™ processes, materials, and manufacturing recipes.

How does giga-thixomolding differ from conventional magnesium die casting?

Can Magnus™ integrate next-generation cell chemistries without an architecture redesign?
