What Winsert, Inc. does

Winsert, Inc. is a privately held, PE-owned advanced manufacturer of proprietary iron-base, nickel-base, and cobalt-base specialty alloys serving heavy-duty internal combustion engine, power generation, aerospace, industrial valve, and food processing end-markets across 35 countries. The company was founded in 1977 by Stephen A. Dickinson as a valve seat insert manufacturer and is headquartered in Marinette, Wisconsin. Its core technology is a patented and proprietary alloy library, anchored by the flagship W77T6-P iron-base alloy (25 million units sold since 1996), designed to displace expensive cobalt- and nickel-based incumbent materials such as Stellite and Tribaloy, with documented customer cost savings of 15-90%. Winsert holds seven granted US, European, and Latin American patents with five more pending, and operates the Stephen A. Dickinson Materials Research Center (10,000 sq. ft., opened 2016) for alloy development, wear simulation, mechanical property testing, corrosion testing, and failure analysis.

The company operates a fully integrated production model spanning sand casting, investment casting (solid mold, ceramic shell, graphite chill), precision multi-axis machining, and metrology, supported by certifications including IATF 16949, AS9100D, NADCAP, ITAR, ISO 14001, and an EcoVadis Bronze sustainability rating. Winsert serves 500+ OEM and Tier 1 customers through a direct enterprise field sales motion, with field sales offices in Munich, Germany and Japan and North American manufacturing in Marinette, WI and (since August 2025) South Bend, IN. The company was acquired by Altus Capital Partners in March 2022 and has since executed a programmatic M&A strategy, acquiring Alloy Cast Products (October 2022) to add the REXALLOY cobalt alloy line and investment casting capacity, and Mack Tool Engineering's aerospace assets (August 2025) to enter aerospace and medical markets. Quantified performance and cost-savings case studies with anchor customers (John Deere, Rolls-Royce Power Systems, INNIO) form the core of its B2B go-to-market, supported by 13 consecutive years of John Deere Partner-level Supplier status and multiple Gold-tier supplier awards.
