4032 Aluminum Round Bar

4032 aluminum bar is an AL-Si alloy and is the highest strength alloy in the 4000 series. It can be heat-treated, has high heat resistance, and excellent wear resistance, making it commonly used for automotive pistons, bearings, and bushings. Due to its high silicon content, it has very low ductility, making this alloy difficult to extrude.

Production process of 4032 aluminum round bars

Casting: First, aluminum ingots are mixed and melted with alloying elements like silicon and magnesium in specific proportions to form the 4032 alloy. The molten alloy is then cast into aluminum billets using processes such as semi-continuous casting.

Extrusion: The cast aluminum billets are preheated, typically around 400°C, and then extruded into round bars using an extrusion press. During this process, the billet is forced into a die to form the round shape.

Heat treatment: The extruded aluminum round bars undergo heat treatment to enhance their strength and hardness. 4032 aluminum is usually subjected to solution treatment and aging (such as T6 treatment) to achieve optimal mechanical properties and deformation resistance.

Stretching and straightening: To ensure good dimensional accuracy and surface quality, the heat-treated round bars are stretched and straightened. This step eliminates internal stresses and ensures the straightness of the bars.

Surface treatment: Depending on requirements, 4032 aluminum round bars can undergo surface treatments like anodizing, polishing, or sandblasting to improve corrosion resistance and appearance.

Quality inspection and packaging: After production, the aluminum round bars are subject to quality inspection, including checks on dimensional accuracy, surface quality, and mechanical properties. Qualified products are then packaged and prepared for shipping or delivery.

Advantages of 4032 aluminum pistons

4032 forged pistons are made from a high-silicon material, which minimizes thermal expansion, allowing for a tighter fit between the piston and bore. This closer clearance results in smoother overall engine operation.

4032 is a very stable alloy that resists distortions such as ring integrity. The strength and stability of this alloy also contribute to a longer lifespan.

Disadvantages of 4032 aluminum pistons

4032 aluminum alloy has poor ductility; therefore, if you plan to build a supercharged HEMI stroker engine, we do not recommend using this type of piston.

4032 aluminum pistons vs. 2618 aluminum pistons

2618 and 4032 are two of the most commonly used piston materials, and there are many differences between them.
