Cast and Extruded Magnesium for Industry
BADGERADVANCED Magnesium from American Carbon delivers high-performance magnesium solutions for structural, thermal, and shielding applications. We specialize in both cast and extruded forms, offering alloy options that balance weight savings, strength, and machinability. Whether your application calls for large die-cast components or precision-extruded profiles, we match the right alloy and form to your technical requirements.
American Carbon has been a trusted supplier of magnesium alloys for nearly a decade, with extensive experience in ASTM B843 alloy magnesium for sacrificial anode systems. As magnesium continues to gain traction as one of the fastest-growing specified structural metals, we support customers across industries - including aerospace, automotive, and energy - by delivering magnesium components optimized for both performance and manufacturability.
Magnesium is 30% lighter than aluminum and offers a comparable strength-to-weight ratio. With modern alloying and improved thermal stability, today's magnesium alloys eliminate many historical concerns. While pure magnesium can be flammable in dust or chip form, properly alloyed and finished magnesium poses no unusual fire risk in structural or shielding applications.
Applications
American Carbon supplies magnesium in forms tailored to your production process. For foundries and anode manufacturers, we offer raw alloyed magnesium ingot to ASTM B843 and other specifications, including AZ91D, AM60, and custom compositions for sacrificial casting, remelt, or alloying additions.
For fabricators and OEMs, we provide near-net and fully finished parts made from common extruded and cast magnesium alloys, including AZ31B, and ZK60. Our parts are used in battery enclosures, electronic housings, transmission cases, instrument bodies, and lightweight frames requiring structural performance, thermal dissipation, or EMI shielding.
Applications include electric vehicle platforms, medical devices, handheld tools, military-grade systems, and industrial enclosures. We also support universities, research labs, and prototype centers investigating magnesium’s role in advanced energy storage, structural components, and shielding assemblies.
Manufacturing Process
BADGERADVANCED Magnesium components are produced through a range of secondary processing methods, depending on the required alloy, form factor, and application.
For complex geometries and high-volume production, we offer high-pressure die casting using alloys such as AZ91D and AM60. This process enables precise, thin-walled parts with integrated features, ideal for housings, covers, and structural casings.
For structural profiles, frames, and machined blocks, we supply extruded magnesium products in alloys like AZ31B and ZK60. Extrusions offer excellent dimensional stability, directional strength, and superior machinability—particularly in applications requiring tight tolerances or lightweight reinforcement.
Finished parts can be supplied as-cast, as-extruded, or fully machined to specification. Our machining capabilities support fine-detail features, tapped holes, multi-axis surfacing, and component integration. Common post-processing includes chemical conversion coatings, corrosion-inhibiting finishes, and custom packaging for sensitive geometries.
