Brass & Copper Machining


Lathed and milled copper part used in the Semiconductor Industry.

Though copper is the third most commonly-used metal in the world, its softness and malleability make it difficult for many in our industry to work with the material. Portland Precision Manufacturing Company has many years’ experience working with copper, and can produce tight tolerance, high precision copper machined parts. Our skilled staff and state-of-the-art CNC equipment allow us to deliver machined copper parts with tolerances of ±0.0005” or better.

Anything you require, from the simplest parts to the most intricate, can be machined to match your exact specifications. CNC technology ensures perfect repeatability from the first part to the last and in any quantity, whether you need a single prototype component or high volume production runs.

Working with Copper

Copper and copper alloys have been used by humans for thousands of years and in a wide range of applications. It is highly ductile and offers excellent thermal and electrical conductivity, making it ideal for use in electronics, communications, and related devices. Thanks to its durability and natural corrosion resistance, copper is also a popular material for architecture and construction.

Copper can be difficult to accurately machine at tight tolerances, but at Portland Precision, we have the know-how to machine the metal with the same high precision as any of the other materials with which we work. We work with most grades of copper and most copper alloys—please contact us for specific material questions or if you require a specialty grade or alloy.

We also offer a variety of secondary operations to add further value to our precision copper machining services. Heat treating, surface finishing, and more are available to save you time and money in your production processes.
