OEMs, Tier 1, Tier 2 and Tier 3

We serve OEM automakers and Tier 1, 2 and 3 suppliers that build vehicles, systems and components under very demanding quality standards and in high production volumes. Their machining, forging, stamping, die cutting and cold forming lines work with tight tolerances and highly repeatable cycles, so every material must offer high mechanical strength, good response to heat treatment, wear resistance and dimensional stability. At NAT MAC we supply machinery-grade and tool-grade steels, carbon and structural steels, aluminum, copper, bronze and brass, plus forging and machining lubricants, band saw blades and measuring equipment. We complement the material with cut-to-size services and technical advice to select the exact grade for each application, so our customers reduce scrap, ensure process repeatability and keep their production lines running.
