Frequently Asked Questions: Automotive Materials

How do your materials help with engine downsizing?

Smaller engines rely on turbocharging to maintain power, which increases internal heat and pressure. Our nickel-base alloys (like 80A and 718) maintain their strength at these elevated temperatures, allowing the engine to remain reliable while reducing its physical footprint.

What makes Chrome Core® 18-FM ideal for fuel injectors?

It is a "Solenoid Quality" ferritic stainless steel. This means it provides the magnetic permeability needed for fast injector actuation while offering the corrosion resistance required to handle modern fuel additives.

Can your materials be used in hybrid vehicle powertrains?

Yes. Our materials are essential for "mild-hybrid" systems where the internal combustion engine must be lightweight and highly efficient to work in tandem with electric motors.

Why is A-286 preferred for exhaust manifold fasteners?

A-286 is an iron-base superalloy that offers much higher strength and oxidation resistance at high temperatures than standard stainless or alloy steels, preventing fasteners from loosening or failing due to heat.
