Cast Aluminum Alloys

A356 & 355 Aluminum Castings

Alcast Company is primarily an A356 permanent mold aluminum foundry, but we have various applications cast with aluminum alloy 355. Feel free to Contact Us to see if we can help meet your A356 or 355 aluminum casting needs.



Sand Castings of Various Aluminum Alloys from
Aluminum Castings Company

Our subsidiary ACC pours sand castings in various aluminum alloys which can be heat treated and/or machined in our aluminum foundry. These alloys include:

Aluminum Alloy 355

355 uses copper to greatly improve its strength over the more common alum. alloy A356. The 355 aluminum alloy is great for pressure tight applications and the alloy also maintains its strength at higher temperatures.

Aluminum Alloy A356

This alloy has higher strength and ductility than 356 because the levels of impurities are lower. A356 aluminum castings cost a little more but are great for machine parts, chassis parts, along with other structural parts requiring high strength or pressure tightness.

Alum. Alloy 356

356 has excellent casting characteristics and corrosion resistance along with good machinability and weldability. Common products manufactured from sand cast alum. alloy 356 include transmission cases, flywheel housings, oil pans, brackets along with various fittings and pump bodies.

Almag 35 (Alloy 535)

The aluminum alloy 535, better known as Almag 35 is a light weight high strength alum. magnesium alloy that doesn't require heat treatment. Almag 35 offers excellent corrosion resistance, machines well and is also dimensionally stable making it great for products such as instruments or marine alum. sand castings amongst other uses.

Tenzaloy 713

As-cast physical properties of are equivalent to the heat-treated 300 series alum. alloys providing a cost savings because heat treatment is not necessary. Tenzaloy is a viable choice for frames, levers and brackets where impact strength or load bearing is required in the aluminum casting.

Aluminum Alloy 319

319 contains around 6% Si and 3.5% copper and is often used for general low cost uses because of its excellent casting and machining characteristics. The 319 sand cast alloy offers very good weldability, pressure tightness, and corrosion resistance making it a great alum. alloy to use for engine components, oil pans, crankcases, gas and oil tanks etc.

Alum. Alloy 771

Alum. sand casting alloy 771 offers high strength and shock resistance without the need for heat-treatment. The 771 aluminum alloy offers good castability, machinability, and corrosion resistance.

Al Alloy 850

Alloy 850 is an alum.-tin alloy often used for bearing applications. 850 alloys are often used in bearing applications where low friction and low cost along with compressive strength, fatigue strength and corrosion resistance is important. Cast aluminum 850 alloy castings are often used for connecting rods, engine bearings, hydraulic pumps, and along with many other automotive and industrial applications.
