HPA's High-Performing Alloys

Our Brochure is available for download or you can view our brochure online!

High Performance Alloys (HPA) maintains a large range of stock in varying high-performing alloys. We also offer many value added services that include, but are not limited to: forging, rolling, size conversion, and heat treating. Our primary cutting services include water jet, band saw, shearing, plasma, and abrasive. Most of our material is available or producable in bar, flat bar, hex, sheet, plate, wire, fasteners, bored bar, tube/pipe, weld wire, and forgings. You can see more of our production capabilities by visiting our capabilities page.

We distinguish our high-performing alloys into 3 classifications (follow the link to quickly access that section):

If corrosion is mitigated, then wear becomes the leading cause of part failure. When a part galls, the part finally ceases to move, seizes or "freezes up." Most of our wear alloys can be easily hardened, cold worked, and retain wear properties as most of the wear resistance is due to the chemistry composition.

Please, note that High Performance Alloys is able to produce most sizes and shapes to your custom needs. Longer leadtimes are usually due to starting stock, so let us know if we can help expedite your procesing.

High temperature resistance is essential in many production applications. Gas turbines, fuel nozzles, heat treating fixtures, and furnace muffles are just a few examples. These materials require very high heat resistant properties, mostly as an extreme oxidation potential and due to strong cycling. Our heat resistant alloys give you the material needed to suit your high temperature environments and applications.

Corrosion is typically the initial cause of part failure. Material corrosion in industrial production usually occurs due to two primary factors: oxidizing acids and reducing acids. Dealing with both types in the operating environment can be challenging and is even worse when operating in high temperatures. Our corrosion resistant alloys will help to ensure your production equipment continues to operate despite harsh environments.
