Fonderie B. Marcoux manufactures custom aluminum alloy castings for industrial applications. We work with grades A356.1, A356.2, A413.1 and A713.1.
Recycled aluminum may also be used when its properties meet the project requirements. A chemical analysis can be provided upon request.

Why choose aluminum for a cast part?
Aluminum is often selected when a project requires a lightweight and durable part. It is also suitable for environments where corrosion resistance is important.
Its final properties vary depending on the alloy and the elements added. The treatment applied and the operating conditions must also be considered.
This versatility makes aluminum suitable for parts with a wide range of shapes, dimensions and functions. Before selecting this metal, several factors should be reviewed, including mechanical loads, temperature and the operating environment.
Exposure to moisture or chemicals must also be evaluated. Tolerances, surface finish and any operations planned after casting may also affect the choice of material.
Aluminum is also recyclable. Fonderie B. Marcoux can assess the use of recycled aluminum when its composition and properties meet the project requirements. The selection must always reflect the part being produced and the client’s quality criteria.
Natural Resources Canada describes aluminum as a lightweight, durable, flexible and recyclable metal.
The Aluminum Association also explains that alloying elements influence the properties of aluminum. Silicon, magnesium and zinc can affect its strength, density, formability and corrosion resistance.
Which aluminum alloys are available?
Fonderie B. Marcoux works with several aluminum alloys. Most of them contain silicon as a primary alloying element. The grades currently available include:
- A356.1;
- A356.2;
- A413.1;
- A713.1;
- recycled aluminum.
Each alloy has a different composition and behaves differently during manufacturing and use. A grade should not be selected simply because it is familiar or commonly used.
It must be suited to the part’s geometry and operating environment. The required performance and drawing specifications must also be considered.
Other options may be considered upon request. Our team can review the project requirements and assess the feasibility of using a different alloy before production is confirmed.
How is the aluminum composition controlled?
The aluminum used by Fonderie B. Marcoux is purchased in the form of ingots. These ingots are supplied with a chemical analysis.
This documentation identifies the composition of the incoming material. It also helps ensure better traceability.
The chemical analysis can be provided to the client upon request. It is particularly useful when a part must meet a specific alloy grade or an internal specification. Industry-specific documentation requirements may also make it necessary.
Composition control is important because the elements contained in the alloy affect its properties. They may also influence its behaviour during manufacturing.
The required grade and documentation must therefore be clearly stated in the request for quotation. They should also appear on the submitted drawings.
