100 YEARS of development and delivery.

In July, 1892, Franklin W. Olin founded the Equitable Powder Company on 300 acres in East Alton, Illinois – the same site where 20 years later he would build the brass mill that remains the centerpiece of Olin Brass today.

The mill continues to churn out the copper alloys that are the foundation of the Olin Brass legacy – alloys developed by our scientists in our laboratories that have in turn fueled technological breakthroughs and product innovations for dozens of companies in a wide range of markets and industries.
