CNC Machining with Hard Metals & Specialty Alloys

Specialty alloys are used in demanding industries where components are machined to strict requirements and high performance is essential. Machining custom parts from hard metals, specialty alloys, and other complex materials calls for advanced manufacturing abilities. Miller CNC utilizes the latest in 3-axis and 5-axis machining technologies to manufacture components from desired materials with precision and reliability.

We machine custom-manufactured parts from hard metals and specialty alloys to provide high-quality machined parts featuring tight tolerances and vital surface finishes. Miller CNC employs AS9100- and ISO9001-certified machining processes to ensure that components are designed and engineered to the highest industry standards.

Hard Metals for Machined Components

Miller CNC specializes in performing CNC machining services using hard metals and specialty alloys. An alloy’s ability to resist deformation determines its classification as a hard or soft metal. This requires applying force to the metal and measuring indentations or impairments. Hard metals can withstand extreme forces while maintaining their properties, making them ideal for CNC machining. Miller CNC uses precision tools to machine hard metals into specialized parts, ensuring accuracy and functionality no matter the component.

Miller CNC Specialty Alloys for CNC Machining Processes

At Miller CNC, we use our advanced CNC manufacturing abilities to create machined components, including fasteners, fittings, manifolds, valves, and additional parts from complex metals and specialty alloys. These components are made from Inconel®, titanium, stainless steel, carbon steel, and other exotic alloys, offering various benefits for unique industrial applications.


A durable superalloy with high nickel content and exceptional resistance to corrosion and oxidation, Inconel® is an ideal metal for high-temperature applications requiring resistance to extreme environments. Inconel® can withstand exposure to salt water, fresh water, air, alkaline chemicals, and high heat. Working primarily with Inconel® in grades 625 and 718, Miller CNC manufactures a range of precise components for specific industrial uses.


Titanium is a versatile hard metal featuring durability and heat resistance. Used in various applications in many industries, titanium provides a lightweight solution with resistant characteristics. Miller CNC utilizes HyperMILL CAM technology to machine high-quality parts primarily using 6AL-4V grade titanium, including structural components, manifolds, and other high-strength implements for aerospace applications.

Stainless Steel

A popular alloy for machining applications, stainless steel provides strength, corrosion resistance, and versatility to manufactured components, which can be cold- and heat-treated to increase durability. While featuring a longer life cycle than brass, nickel, or titanium, some stainless steel grades can pose manufacturing challenges. Miller CNC has expert machining capabilities to work with stainless steel in options including the 300 series, 400 series, 13-8, 15-5, and 17-4.

Carbon Steel

Focusing on high-tensile grades of carbon steel, our CNC manufacturing capabilities include heat treatment or case hardening before finishing carbon steel components to tailor physical properties to specific applications. Miller CNC partners with suppliers that perform non-traditional machining methods such as grinding, honing, and EDM for increased options for carbon steel components.

Exotic Alloys

Exotic alloys such as Kovar, Monel, and Hastelloy are challenging to machine because they feature improved strength and resistance to wear, corrosion, and heat. Developed for industry-specific applications, exotic hard metals require expert machining to provide the precision and accuracy necessary for mission-critical components. Utilizing 5-axis machining and HyperMILL CAM software, Miller CNC manufactures advanced, high-performance machined parts. Our technology offers enhanced efficiency through reduced set-up times, and our software provides precision simulations resulting in machined features without physical handling of the component.
