The Machinists Dream

Aluminum Castings the OLSON WAY

We care that you get the right process for your parts...That's why you can contact us without worrying about sales pressure to get our expert opinion of the best process to make your parts faster, easier and better, for less.

Castings produced by Olson Aluminum will exhibit machining characteristics equal to, and in many cases, better than bar stock or billet aluminum. Our process begins with chemical property requirements on all incoming alloy. Magnesium levels are controlled to attain a consistent Brinell Hardness reating (BHN).


We complete the process by removing harmful hydrogen gases, oxides and dross prior to pouring. This process, along with our in-house heat treating capabilities, assure superior T6 and BHN results.

Our commitment to these critical process controls assures a high degree of grain refinement and consistency that is necessary to achieve desired characteristics, such as:
