Stainless Steel

Known for its natural corrosion resistance and unique appearance, stainless steel is the preferred material for parts used in applications from aerospace to medical and beyond. With our stainless steel fabrication capabilities, we can produce precision parts from any grade or alloy of this popular material.

Kovar, Invar & Inconel

These unique, high nickel-content alloys exhibit excellent dimensional stability, making them ideal for precision parts in high heat and/or high pressure applications. We have been working with Kovar, Invar, and Inconel for over 30 years, and have the expertise to deliver parts that match your designs perfectly.

Tool Steels

With high hardness and excellent abrasion and deformation resistance, tool steels are, as the name suggests, commonly used to produce tools and tooling, along with parts for physically demanding applications. With our tool steel fabrication capabilities, we can deliver the high precision parts you need.


Tungsten, and other powdered metals, are extremely hard and notoriously difficult toTungsten precision ground tungsten finmachine and grind, but Petersen Precision has the capabilities to produce precision-ground powdered metal parts with fine features and tight tolerances of up to a few microns. Our powdered metal grinding and fabrication processes enable us to deliver the perfect parts for your application. 


Thanks to its high strength-to-weight ratio, aluminum is popular for a wide range of applications, from household items to complex aerospace components. We have the aluminum fabrication capabilities to produce high precision parts from all grades of aluminum.


Titanium exhibits high tensile strength with low density, as well as excellent stiffness and toughness, making it Titanium high precision fineblankingthe material of choice for applications ranging from aerospace to medical and beyond. We have the titanium fabrication capabilities to produce the high precision, tight tolerance parts you need.

Exotic Metals & Alloys

From molybdenum to platinum to Hastelloy and many more, Petersen Precision has the experience and the expertise to work with the exotic metals and exotic alloys your application requires. We will help you find the perfect material for your unique needs and deliver high precision parts that match your designs exactly.
