Aluminum alloy
333 & A333 aluminum castings
A permanent mold favorite with better as-cast properties than 319 at a similar price.
333 and A333 cast well in permanent molds and have better as-cast mechanical properties than 319-type alloys at a similar price point, which makes them common for permanent mold products.
They offer good weldability, pressure tightness and corrosion resistance.
We cast 333 in green sand, no-bake and permanent mold, and machine and heat treat it in-house.
- Composition
- 8 to 10% silicon and 3 to 4% copper, with up to 1% iron and zinc and small amounts of magnesium, nickel and titanium; the balance is aluminum.
- Typical uses
- Permanent mold parts, housings 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.
- C355Copper-strengthened and pressure-tight, and keeps its strength at higher temperatures than A356.
- 319A versatile aluminum-silicon-copper alloy with good strength as cast.
- 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.
