Aluminum Sand Casting Foundry
We have over 20 years of experience in the design and manufacturing of quality aluminum sand castings.
Sand mold casting is the most direct and low cost means of converting metal into a desired shape. Aluminum castings are virtually unlimited in their ability to provide users with a wide range of advantages and applications.
Aluminum has a high strength-to-weight ratio that is approximately one third the weights of cast iron, steel, brass and zinc.
With excellent corrosion resistance, reduced machining cycles, and the ability to anodize, buff, electroplate and powder coat, aluminum castings make it more cost effective than a welded component, stamping or forging.
The light weight of aluminum, the improved strength that engineered alloys offer, and the increased ability of the sand casting process to produce stronger and thinner walled parts allow us to produce a variety of castings for our customers ranging in size from 1 ounce up to 600 pounds.
319 Aluminum Sand Castings
Aluminum alloy 319 is a 6% Si and 3.5% Cu alloy with 1.0 Fe maximum. It has excellent casting and machining characteristics. Corrosion resistance and weldability are very good. Mechanical properties are good in both the heat-treated (T5) and non-heat treated conditions.
The anodized color is generally gray with a brown cast depending on the amount and ratio of silicon and copper.
Typical applications for sand casting 319.0 are a wide variety of structural castings for engine parts, engine crankcases, gas and oil pans, and general commercial applications.
