As a trusted leader in HIGH QUALITY CUSTOM CASTINGS, Trumbull Foundry provides the superior Gray Iron and Ductile Iron components essential for the performance and durability of today's vehicles. While we serve a broad range of demanding markets, our domestically-produced, high-performance alloys meet the stringent requirements of the automotive sector, where parts must withstand extreme heat, friction, and continuous operational stress.


Core Automotive Applications Utilizing Trumbull Alloys


Our expertise in ferrous casting ensures reliable performance for critical automotive systems:

  • Engine & Powertrain Components: We cast high-quality Gray Iron for parts like Engine Blocks and Cylinder Heads, utilizing its excellent thermal conductivity and machinability. For components requiring higher strength and fatigue resistance, such as Differential Housings and heavy-duty transmission parts, we utilize robust Ductile Iron.

  • Braking Systems: Trumbull's Gray Iron is the preferred material for Brake Rotors and drums due to its outstanding ability to absorb and dissipate heat, providing superior frictional properties and resisting thermal cracking under high-stress braking conditions.

  • Chassis & Suspension: For components that manage vehicle load and impact, such as Suspension Parts and steering knuckles, our high-strength Ductile Iron castings provide the necessary impact resistance and fatigue life required for vehicle stability and long-term safety.

  • Exhaust Systems: We supply specialized castings for Exhaust Manifolds that must operate reliably in high-temperature and corrosive gas environments, engineered to resist thermal expansion stresses.


The Trumbull Foundry Advantage: Custom Solutions and Quality


Trumbull Foundry is committed to shaping success through superior castings and exceptional service, supporting the automotive supply chain with key advantages:

  • Rapid Prototyping: We offer Rapid Prototyping services designed to deliver precision and speed without compromise, helping manufacturers streamline product development and overcome engineering challenges efficiently.

  • Diverse Alloy Capabilities: While Gray Iron and Ductile Iron are primary materials for the applications above, our casting capabilities also extend to Alloy Castings and Steel Castings, allowing us to meet specialized performance needs across the supply chain.

  • Made in USA: All our custom metal casting solutions are proudly Made in USA, ensuring consistent quality, reliability, and simplified supply chain logistics for North American partners.
