Hammerer Aluminum Industries

What Hammerer Aluminum Industries does

Hammerer Aluminium Industries (HAI) is a privately held Austrian aluminium solutions provider founded in 2007 as a spin-off from Austria Metall AG, headquartered in Ranshofen, Austria, with nine manufacturing locations across Austria, Germany, Romania, Poland, and South Korea. HAI operates a vertically integrated model spanning three divisions — Casting (foundry products: extrusion billets, rolling slabs, sows, desox aluminium; 250,000 tonnes per year across Ranshofen and Sântana using Wagstaff AirSlip® mould technology), Extrusion (12 direct presses from 800 to 6,100 tonnes), and Processing (friction stir welding, milling, bending, assembly). The company employed roughly 1,900 people and reported €823 million in FY2024 revenue.

HAI sells exclusively B2B to enterprise customers via dedicated sales directors per vertical — Transport (Mercedes-Benz, BMW, Daimler/JLR, BorgWarner for automotive and e-mobility; TSB Max Bögl, Carvatech for rail), Construction (ALUKÖNIGSTAHL, ALUMERO, K2 Systems), and Industry (machinery, electrical, heat sinks up to 18:1 aspect ratio). The value proposition rests on a one-stop-shop integrated chain, fast time-to-series production through in-house toolmaking, and a proprietary low-carbon alloy portfolio — SustainAl 2.0 (≤2 t CO₂e/t Al) and SustainAl 4.0 (≤4 t CO₂e/t Al) — backed by ASI Performance Standard certification across all major sites, EcoVadis Silver, and ISO 14001/45001/50001.

The business model is project-based direct sales with negotiated, non-public pricing. HAI monetises three integrated streams: cast product sales (billet, slab, sow and desoxal aluminium, including external sales), extrusion profile sales across automotive, construction, and industrial end-markets, and processed components (FSW battery housings, structural crash components, machined assemblies). Recent strategic emphasis is on sustainable/low-carbon alloys, e-mobility solutions (battery trays, crash components), and European vertical integration supported by €125M (2024) and €100M (2022) investment programmes, a Korean JV with LS C&S opened May 2025, and a March 2026 strategic stake in Aluminij Industries.

Revenue model

1. Aluminium Casting Products: HAI operates two of the most modern and flexible foundries in Europe producing extrusion billets, rolling slabs, sows and desox aluminium. The casting division sells molten metal and cast products to downstream extrusion operations as well as external customers. With an annual capacity of approximately 250,000 tonnes, casting products serve as the raw material input for the company's integrated extrusion and processing operations, as well as being sold externally.
2. Aluminium Extrusion Profiles: HAI produces high-quality aluminium profiles across multiple industry verticals (transport, construction, industry) using 12 direct presses with press forces ranging from 800 to 6,100 tonnes. Profiles are sold directly to OEM customers and tier 1 suppliers. The company offers both standard and custom alloys (15 standard and special alloys), micro and precision profiles (tolerances of +/- 0.05 mm), and specialized products such as crash-resistant alloys, gloss alloys, and electrical conductivity alloys.
3. Aluminium Processing and Components: HAI provides mechanical further processing of aluminium profiles including friction stir welding, gas-shielded welding, mechanical jointing and riveting, chipping/milling, forming/bending, assembly, and special machine production. Components such as battery housings, structural rail components, and automotive body parts are produced and sold as finished or semi-finished assemblies to customers. Revenue is generated through the sale of machined, welded, and assembled aluminium components.

Direct peers

• Constellium SE: Specialises in aluminium rolled products, extrusions, and structural components for automotive, aerospace, and packaging end markets. Closely comparable to HAI's transport and e-mobility focus, with overlapping capabilities in crash-optimised automotive structures and battery enclosure components.
• Gränges AB: Specialises in rolled aluminium products and heat exchanger strip for automotive, HVAC, and speciality applications. Comparable to HAI in serving automotive and industrial customers with engineered aluminium solutions, including sustainability-focused offerings.
• Norsk Hydro ASA: One of the largest integrated aluminium producers globally, with primary aluminium, extrusion, and downstream operations serving transport, construction, and industrial customers. HAI actually acquired Norsk Hydro's Romanian extrusion plant in 2019–2020, making Hydro a former asset supplier and the most direct integrated competitor in extrusions.
• AMAG Austria Metall AG: Austrian integrated aluminium company — and the entity from which HAI was spun off in 2007. AMAG operates primary smelting, casting, rolling, and recycling, making it a direct geographic and operational peer to HAI's Austrian casting and rolling-slabs operations.
• Kaiser Aluminum Corporation: Produces semi-fabricated specialty aluminium mill products, including extrusions, for aerospace, automotive, and general engineering end markets. Overlaps with HAI's extrusion and engineered component capabilities, particularly in transport and industrial applications.
• Mifa Aluminium BV: Dutch precision aluminium extrusions specialist serving automotive, lighting, electronics, and industrial customers. Comparable to HAI's extrusion capabilities in terms of product category and customer overlap, though smaller in scale and lacking HAI's integrated casting and processing.

Broad incumbents

• Alcoa Corporation: Global primary aluminium and bauxite producer with downstream alumina refining and a portfolio of value-add businesses. Provides upstream context for HAI's billet sourcing and is comparable as a major aluminium industry incumbent, although Alcoa's downstream footprint is narrower than HAI's integrated casting-to-processing model.
• Arconic Corporation: Global supplier of aluminium sheet, plate, extrusions, and architectural systems serving aerospace, automotive, construction, and industrial markets. Comparable to HAI's broader portfolio across transport, construction, and industry, but with substantially larger scale and an aerospace tilt.
• Novelis Inc. (Hindalco Industries): World leader in aluminium rolling and recycling, supplying automotive, beverage can, and speciality markets. As a much larger flat-rolled and extrusion competitor with deep automotive OEM relationships, Novelis is a broad incumbent comparable to HAI's rolling slab and automotive sheet-adjacent offerings.

Others

• Wagstaff, Inc. Technology partner and exclusive supplier of Wagstaff AirSlip® billet casting technology to HAI's Ranshofen and Sântana foundries. While Wagstaff is a technology supplier rather than a competitor, it is a key ecosystem participant and enabler of HAI's thin-edge-zone casting capability.
