High-Performance Automotive Alloys

We’re meeting the needs of automotive manufacturers for stronger, more corrosion-resistant alloys to boost performance and meet regulatory requirements.

Alloy Applications

in the Automotive Industry

New engine ratings and pollution control requirements are creating new applications for INCOLOY®, INCONEL® and NIMONIC® alloys.

Auto Applications

Exhaust systems, exhaust valves, spark plugs, ignition equipment, sensors, electrical and electronic switchgear, and safety devices.


INCONEL® Catalytic Converters

Catalytic converters use INCONEL® alloy 601 & age-hardenable INCONEL® alloy X-750 to resist thermal & mechanical fatigue at over 1,600° F.


NIMONIC® Stands the Heat

Special Metals Corporation’s high-temperature alloys serve the automotive parts industry in heat-treating equipment.
