What Audubon Metals does

Audubon Metals LLC is a privately held secondary aluminum alloy producer and heavy media separator headquartered in Henderson, Kentucky, and operating a second production site in Corsicana, Texas. Founded in 1996 as a single-furnace operation and grown to a seven-furnace, multi-site platform, the company is a wholly owned subsidiary of Koch Enterprises, Inc. Its core process takes Zorba — mixed non-ferrous metals recovered from automotive shredder residue — and, via heavy-media separation, isolates Twitch (shredded cast and wrought aluminum grades) for melting and conversion into specification aluminum alloys in ingot, sow, and low-profile sow forms. By-products of the separation (Heavies, mixed Magnesium scrap, and shredded electronic scrap) are sold separately. Audubon also holds a license to Ohio State University technology, supported by the U.S. Department of Energy's REMADE Institute, for neutralizing iron contamination in aluminum scrap, with the resulting alloys targeting mechanical properties comparable to primary alloys used in die casting.

The company manufactures over 100 variants of specification aluminum alloys, including common die-casting grades such as A319, A356, A360, A380, A383, A390, A413, and ADC12, and operates on a 42-day average cycle from automobile shredding to shipped casting. Its stated throughput exceeds 500 million pounds of non-ferrous recyclable metals annually. Customers are primarily die casters and industrial OEMs across automotive (the lead vertical, including DENSO, Bocar Group, Honda, and Nissan), construction, lawn and garden, marine, ATV/side-by-side, and consumer goods, with both domestic and international shipments. Revenue is generated through transaction-based sales of specification alloys and by-products under negotiated, multi-year commercial arrangements with enterprise buyers, supported by metallurgical, quality, technical operations, scrap/materials management, and logistics services.

Audubon maintains ISO 9001, ISO 14001, and ISO 45001 certifications, GreenCircle Certified sustainability status, and a record of consecutive NADCA safety awards and recurring OEM quality awards. Distribution is direct and field-led through an enterprise sales team, with marketing layered through industry association memberships, earned media from customer awards, and digital/social presence. The combination of proprietary process technology, large-scale secondary processing capacity, and entrenched Tier-1 OEM qualifications forms the basis of its competitive positioning.

Core offering

Audubon Metals is a heavy media separator and secondary aluminum alloy producer that converts Zorba (mixed non-ferrous metals from automotive shredder residue) into specification aluminum alloys for die casting applications. The company manufactures over 100 variants of alloys in ingot, sow, and low-profile sow forms across seven furnaces at two U.S. facilities (Henderson, KY and Corsicana, TX), processing over 500 million pounds of non-ferrous recyclable metals annually.

Product overview

Audubon Metals operates as a secondary aluminum alloy producer and heavy media separator with a portfolio of products centered on recycled aluminum processing. The core offering is Specification Aluminum Alloys, produced in three forms: ingot, sow, and low-profile sow. Raw material input is primarily Twitch (derived from processing Zorba), which is melted and alloyed to customer specifications. The company also generates recyclable by-products including Heavies (mixed stainless, zinc, copper, brass), Magnesium, and E-Scrap. Supporting the product portfolio, Audubon Metals provides technical services including metallurgical chemistry, quality assurance, and logistics support. The company manufactures over 100 variants of aluminum alloys including common grades such as A319, A332, 356, A360, A380, A383, 390, A413, and ADC12, serving die casting manufacturers across automotive, construction, lawn & garden, marine, and consumer goods industries.
