FREQUENTLY ASKED QUESTIONS

How does Carpenter Technology support weight reduction in rotorcraft?

We offer high-strength-to-weight ratio alloys like MP35N® and Custom 465®, which allow engineers to design smaller, lighter components that maintain the structural integrity of larger, heavier steel parts.

What materials do you recommend for high-corrosion environments like naval operations?

For marine helicopters exposed to salt spray, we recommend our Custom 465® stainless steel, which provides the high strength of alloy steels with the superior corrosion resistance of stainless.

Do you provide additive manufacturing (AM) powders for rotorcraft parts?

Yes. Carpenter Additive provides a global footprint of atomization capabilities, producing high-quality powders for standard and custom alloys specifically for aerospace and defense AM applications.
