Founded in St. Louis in 1974, Metal Exchange Corporation has grown from a regional aluminum scrap trading company to a global trader and manufacturer of nonferrous metals.

MEC Founder, Morris Lefton

Ingrained in the minds of every Metal Exchange Corporation employee is the motto of our founder, Morris Lefton: Nisi adieris non intellegis. (“If you don’t go, you don’t know.”) This brief statement encompasses the culture of Metal Exchange Corporation. Visit the customer. See their operations. Understand their needs.

This is how we’ve built and maintained the foundation of Metal Exchange Corporation: long-term relationships with customers and suppliers based on trust, integrity and reliability.
