Exxentis

What Exxentis does

Exxentis AG is a privately held Swiss specialty manufacturer founded in 2011 and headquartered in Wettingen, near Zurich. The company produces porous aluminium (offenporiger Aluminiumschaum) using a proprietary salt-casting process in which liquid aluminium is poured together with crystal salt into conventional casting molds; the salt is washed out after mechanical processing, leaving an open-cell, interconnected porous structure with 55-65% volume porosity. Exxentis offers seven standard pore sizes (0.20mm to 4.00mm) in standard forms (plates, blocks, cylinders, complex shapes) and can cast porous and solid aluminium sections monolithically in a single piece. Beyond raw stock, the company engineers application products including pneumatic silencers, vacuum tables and clamping plates, industrial filters and filter elements, heat exchangers, fluidized-bed plates, thermoforming and vacuum-forming tools, lightweight construction material, and weapon sound suppressors.

The company operates a direct, sales-led go-to-market model: every new application involves individual technical consulting with the customer, followed by custom manufacturing to specification in volumes ranging from prototypes to large series. Pricing is quote-based and not publicly disclosed; sample plates are stocked in Switzerland for fast delivery across Europe. Since 2019, Exxentis has also acted as the Swiss representative of a large manufacturer of zirconium, hafnium, calcium, niobium, and tantalum, extending its product portfolio into refractory and reactive specialty metals. The company is privately held, has no disclosed funding rounds or institutional investors, and serves European industrial customers across a horizontal set of verticals including manufacturing equipment, pneumatic OEMs, industrial filtration, heat exchange (automotive, EV, aerospace), plastics processing tooling, lightweight construction, fluidization systems, and weapons suppression.

Core offering

Exxentis AG manufactures custom porous aluminium products through a proprietary salt casting process, producing plates, blocks, cylinders, and complex-shaped components with controlled 55-65% volume porosity across seven standard pore sizes (0.20mm to 4.00mm). The company also delivers application-specific finished products including pneumatic silencers, vacuum clamping plates, industrial filters, heat exchangers, fluidized bed components, thermoforming tools, and lightweight structural materials for European industrial customers.

Product overview

Exxentis AG is a Swiss manufacturer and supplier of porous aluminum (offenporiger Aluminiumschaum), a permeable metal material produced through an innovative salt casting process. The company offers a comprehensive portfolio of porous aluminum products including standard forms (plates, blocks, cylinders) and custom complex shapes, with the option to combine porous and solid aluminum in monolithic castings. The product range spans seven standard pore size types (0.20mm to 4.00mm) with consistent 55-65% volume porosity. Beyond raw material forms, Exxentis manufactures finished application products including pneumatic silencers (in threaded, cylindrical, high-performance, and flat variants), vacuum plates for vacuum tables, filters and filter elements, heat exchangers, fluidized bed components, weapon sound suppressors, vacuum/thermoforming tools, and lightweight construction materials. The company was founded in 2011, operates from Wettingen, Switzerland, and serves customers across various industrial sectors in Europe.

Broad incumbents

• RUSAL: World's largest aluminum producer outside China, with growing value-added product portfolio. Comparable to Exxentis at the upstream end of the aluminum value chain, and increasingly in value-added components for automotive and aerospace.
• Alcoa: Global aluminum major producing bauxite, alumina, and primary aluminum with downstream value-added components. Operating far upstream of Exxentis but represents the supply chain backbone whose aluminum alloys Exxentis uses as raw material.
• Constellium: Global aluminum value-added components supplier for aerospace, automotive, and packaging. Indirect peer to Exxentis in lightweight aluminum components, but at much larger scale and broader product portfolio.
• Norsk Hydro: Global aluminum producer with growing focus on extruded and value-added components. Comparable to Exxentis in serving automotive and construction aluminum components, but at a vastly larger scale as a primary and secondary aluminum producer.
• GKN Sinter Metals: Global leader in sintered metal components including sintered filters that directly compete with Exxentis' porous aluminum filters. A larger, established incumbent with broader product portfolio and global OEM relationships.

Direct peers

• Mott Corporation: US manufacturer of porous metal filters and flow control components. Directly comparable to Exxentis in industrial filtration (gas, liquid, hot gas), but uses sintered metal rather than cast porous aluminum — a competing material architecture in the same end markets.
• ERG Aerospace: US-based manufacturer of Duocel® open-cell aluminum foam. Direct competitor offering porous aluminum components for the same filtration, heat exchange, and lightweight structural applications addressed by Exxentis.
• Aluinvent: Hungarian manufacturer of aluminum foams and porous aluminum components using proprietary methods. Direct competitor to Exxentis in the open-cell porous aluminum market, with similar product positioning for filtration, lightweight construction, and energy absorption.
• Havel metal foam: German manufacturer of metal foams including aluminum foam products. Closely comparable to Exxentis in process and target applications, with particular overlap in lightweight construction and impact energy absorption.
• Pohltec Metalfoam: German aluminum foam specialist focused on automotive, aerospace, and machinery applications. Directly comparable to Exxentis in serving lightweight structural components and heat exchange with porous aluminum.
