About Winsert


Why Winsert?

Winsert is a leading global provider of innovative alloy solutions to a variety of industries.  The four cornerstones of Winsert have allowed us to earn the reputation of not being just "another supplier", but a partner to our OEM customers.​​  Winsert's expertise spreads to all four critical areas and we continue to build upon each cornerstone.  We form lasting partnerships by working directly with major OEMs throughout the course of their projects.  Our teams work together to develop, test, and produce the proper solutions for the OEM applications.

Winsert provides corrosion-resistant, wear-resistant, and high temperature alloys for various applications within internal combustion engines, aerospace, emission controls, industrial valves, and food processing.

"Winsert's modern manufacturing facility, robust processes, and new R&D center are truly impressive.  Seeing  your place again just reinforces the value of our partnership."

​In addition to manufacturing components in traditional common trade materials, Winsert utilizes patented and proprietary alloys to develop fast, effective, and affordable solutions for our OEM partners.  Winsert's alloys serve as true replacement materials for expensive high cobalt and nickel content materials.  With the ever-fluctuating metal markets and cobalt instability, our patented and proprietary alloys, many which have been tested and validated by our OEM partners themselves, provide peace of mind in terms of proven performance as well as cost savings and cost stability.  Winsert helps our partners #removethecobalt from their components and applications.
