ForTii® MX for metal replacement

The cost-effective alternative for die-cast metal replacement between -35°C and 160°C

ForTii® MX

The polyamide for die-cast metal replacement

If you’re looking to unlock new design potential in automotive applications – boosting performance, cutting fuel emissions and reducing cost of ownership - then ForTii PA4T metal replacement (MX) portfolio is your number one choice. The ForTii MX portfolio contains semiaromatic polyamides, based on DSM’s PA4T technology, enabling you to engineer the incredible, by thinking beyond metal and beyond its traditional alternatives. ForTii is tested extensively in parts, since testing of tensile bars does often not represent the part complexity (ribs, weldines, inserts) in the real world.
