Aluminum alloy
C355 aluminum castings
Copper-strengthened and pressure-tight, and keeps its strength at higher temperatures than A356.
Copper gives C355 substantially more strength than A356, and it holds that strength at higher temperatures. It is usually heat treated for maximum strength.
It suits pressure-tight applications in sand and permanent mold, such as compressor housings and high-performance engine parts.
We cast C355 in green sand, no-bake and permanent mold, and machine and heat treat it in-house.
- Composition
- About 5% silicon, 1.25% copper and 0.5% magnesium, with low iron; the balance is aluminum.
- Typical uses
- Compressor housings, pressure-tight and high-temperature parts.
- 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.
- 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.

What Is An Alloy
A metal alloy tends to be harder/stronger and more durable than pure metal because the mixture has atoms of different sizes. Alloys also provide resistance to corrosive environments and can improve appearance of products, as they are lustrous and contain a better finish.

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.
