Aluminum alloy
319 aluminum castings
A versatile aluminum-silicon-copper alloy with good strength as cast.
319 combines good castability with strength and machinability, and performs well in both sand and permanent mold.
It is a common choice for parts that need moderate strength without heat treatment.
We cast 319 in green sand, no-bake and permanent mold, and machine and heat treat it in-house.
- Composition
- About 6% silicon and 3.5% copper, with iron at 1.0% maximum; the balance is aluminum.
- Typical uses
- Housings, brackets and engine components.
- Processes
- Green sand, no-bake, permanent mold
Other alloys we pour
- A356The higher-purity version of 356: strong, ductile and corrosion resistant, usually heat treated to T6.
- 356The general-purpose workhorse: good castability, weldability and pressure tightness at a good price.
- 333 & A333A permanent mold favorite with better as-cast properties than 319 at a similar price.
- C355Copper-strengthened and pressure-tight, and keeps its strength at higher temperatures than A356.
- 535 (Almag 35)High strength and excellent corrosion resistance without heat treatment.
- 713 (Tenzaloy)Reaches high strength at room temperature, with no heat treatment and high impact strength.

A Guide To Non-ferrous Metal Alloy Casting
Metal casting is a complicated process that involves pouring liquid metal into a mold, allowing it to cool, and then extracting the product. Depending on the metal used and the required outcome, we utilize sand casting or permanent mold casting to create prototypes and products. Non-ferrous sand casting is highly efficient and cost-effective. Permanent mold utilizes gravity when pouring molten aluminum into molds (or dies) machined from cast iron or steel. Ermak takes pride in producing high-quality castings that are consistent, repeatable, and cost-effective. We customize the casting process to meet your needs using the best, most efficient non-ferrous metal casting process for your product.

Aluminum applications span from everyday items like fuel-efficient vehicles to smart phones to window frames to airplanes. It has a long list of inherent assets that makes it referred to as a “miracle metal” – lightweight, corrosion resistant, easily formed, highly conductive, highly reflective, non-toxic, durable and recyclable – and gives manufacturers and designers a wide range of options for product innovation and process improvements.
