MetalTek International

What MetalTek International does

MetalTek International is a privately held U.S. specialty metal casting manufacturer founded in 1945 and headquartered in Waukesha, Wisconsin. The company manufactures precision metal components for demanding industrial applications across aerospace, defense, petrochemical, turbine engine, process equipment, renewable energy, pulp and paper, and other heavy-industrial markets. Its core technology portfolio spans centrifugal casting, sand casting, investment casting, high-integrity ingot production, and AOD refining, supported by integrated capabilities in metallurgy and engineering, heat treatment, precision machining, fabrication, testing and analysis, and laser powder bed fusion (LPBF) additive manufacturing using a proprietary MTEK 718 nickel superalloy. The company operates four specialized divisions (Carondelet in Pevely, MO; Sandusky International in Sandusky, OH; Wisconsin Centrifugal in Waukesha, WI; Wisconsin Investcast in Watertown, WI) plus an Oil Systems division, with over 200 machining centers, more than 100 metallurgists and engineers, and over 450 ferrous and non-ferrous alloys routinely poured, including proprietary grades. MetalTek holds Nadcap, AMS 2750, ASME Section IX, and NAVSEA Tech Pub 300 certifications, with over 70 years of defense supply history including the production of HY-80 steel castings for the U.S. Navy.

MetalTek generates revenue through custom B2B manufacturing of metal components sold under quote-based pricing tied to specification, alloy selection, volume, and processing requirements. Distribution is entirely direct via market-segment Key Account Managers covering Aerospace, Defense, Energy, Petrochemical, Turbine Engine, Process Equipment, Renewable Energy, Paper, Food Processing, Mining, and Power Transfer markets, with no apparent distributor or reseller channel. The company markets through technical content (blog, case studies) and a TekSession training program that serves both customer education and demand generation. Named customers include the U.S. Navy/NAVSEA, aerospace turbine manufacturers, defense missile manufacturers, naval pump and valve manufacturers, food processing equipment makers, and the Pentagon Memorial. The company employs between 501 and 1,000 people and is currently led by CEO E.J. Kubick following the August 2024 passing of former CEO Bob Smickley. No funding rounds, acquisitions, or parent company are disclosed; ownership is private and the operating status is active.

Direct peers

• Scot Forge: Scot Forge is a leading North American producer of open-die and forged products serving aerospace, defense, power generation, and petrochemical markets. It is comparable to MetalTek as a U.S.-based industrial metals manufacturer serving similar safety-critical end markets, though focused on forgings rather than castings.
• Ellwood Group: Ellwood Group is a privately held specialty steel manufacturer and foundry producing castings, forgings, and machined components for industrial markets including steel mills, defense, and energy. It directly competes with MetalTek's Carondelet and Sandusky International divisions on large ferrous castings.
• Haynes International: Haynes International develops and manufactures high-performance nickel- and cobalt-based alloys for use in castings and other forms. It is a partner in the NETL ComTest project alongside MetalTek and competes in part by supplying alloys that foundries (including MetalTek) consume and, in some cases, by producing finished cast components itself.
• Doncasters Group: Doncasters is a global manufacturer of precision-engineered castings and forgings serving aerospace, defense, and industrial gas turbine markets. It directly competes with MetalTek in investment casting and high-temperature alloy components for turbine engine applications.
• Signicast (Form Technologies): Signicast is one of the largest investment casting foundries in North America, serving aerospace, defense, industrial, and commercial markets. It directly competes with MetalTek's Wisconsin Investcast Division on precision investment castings for aerospace and defense applications.
• Howmet Aerospace: Howmet Aerospace is a leading global supplier of aerospace castings, superalloys, and titanium aluminides. It directly competes with MetalTek on investment castings and high-temperature nickel alloy components for aerospace and defense customers, though at substantially larger scale.
• Precision Castparts Corp: PCC, a Berkshire Hathaway subsidiary, is one of the world's largest manufacturers of complex metal components including investment castings and forgings for aerospace and industrial markets. PCC is a ComTest partner alongside MetalTek and competes head-to-head on high-integrity aerospace castings.

Broad incumbents

• voestalpine: voestalpine is a global steel and technology group with a specialty forging and casting division serving railway, aerospace, energy, and industrial markets. It is a broad incumbent comparable to MetalTek on high-specification steel components for energy and transportation customers, but at substantially larger scale and with broader product scope.
• Carpenter Technology Corporation: Carpenter Technology is a leading producer of specialty alloys including nickel, cobalt, and titanium for aerospace, defense, and industrial markets. While it does not operate a foundry at the scale of MetalTek, it competes as a specialty alloy producer and supplies many of the same end customers with wrought and powder metal products.

Others

• Bodycote: Bodycote is the world's largest provider of heat treatment and metal joining services, with hundreds of furnaces globally. It is an ecosystem peer to MetalTek's in-house heat treatment capability — competing for outsourced heat-treatment work and providing complementary capacity.
