Our specialty is large aluminum castings in 535.0 (Almag 35). This alloy requires no heat treating and has good tensile properties and high ductility, outstanding corrosion resistance and excellent dimensional stability. It machines much easier than the more common silicon containing aluminum allys, producing an excellent surface finish and requires no intermediate stress relieveing as it does not distort during machining.

We also produce large and small castings in A356.0 and 356.0 alloys which are usually heat treated to a T5 or T6 condition. These alloys offer excellent tensile properties and good castability.

Zinc castings we produce range from 20 to 16,000 pounds and are used primarily for trim and forming dies.

Along with our move to new facilities, we have added the capability of producing castings in copper base alloys.

With many years of casting experience, we can assist you in designing economical castings to meet your needs.

Many of our customers and potential customers have been requesting completely machined, anodized, painted and sometimes assembled components rather than only raw castings. Because meeting our customers' needs is our number one priority, we have decided to expand our services to include these value-added operations.

In order to accomplish this we have established relationships with several local companies who are capable of providing these additional services. Our customers can now place a single order for components that are ready for final assembly at their facility. We take care of scheduling and coordinating all operations as well as assuring compliance with all order requirements.

We have supplied:

Completely machined, anodized and painted components to the US Navy;

Partially machined mill fixture castings to Boeing;

Completely machined, anodized, inserts installed, pressure tested and painted components to Twin Commander Aircraft Corporation;

Painted and sanded logo castings to Cincinnati, Inc.

Let us know what you need.

Below you will find listed the typical alloys and casting sizes we can produce as well as pictures of castings we've made.
