Thalheimer Brothers, which scraps and ships copper, nickel, stainless steel and other metals to factories from its 400,000 sq ft plant on 20 acres at 5500 Whitaker Ave., Lawncrest, says it has purchased Baltimore-based Ansam Metals, a buyer and processor of copper-nickel and other brass, for an undisclosed sum. In a statement, Ansam president Ben Zager said he and his staff look forward to working with Thalheimer.

The deal follows Boston-based Audax Group's investment in Thalheimer last December in hopes of "penetrating new geographies" and other markets, Audax chief executive officer Geoffrey Rehnert said at the time.
