History of Pennex

Pennex is part of Metal Exchange Holdings, a Metal Exchange company. Metal Exchange was founded in St. Louis in 1974, and has grown from a regional aluminum scrap trading company to a global trader and manufacturer of nonferrous metals.

Ingrained in the minds of every Metal Exchange and Pennex 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 the Metal Exchange family of companies that includes Pennex. Visit the customer. See their operations. Understand their needs. This is how we’ve built and maintained the foundation of Metal Exchange: long-term relationships with customers and suppliers based on trust, integrity, and reliability.
