Extruded Aluminum Profiles Cost Structure

The cost of custom extruded aluminum profiles is determined by several key components throughout the production and finishing process:

• Raw Aluminum Ingot Price – The largest cost factor comes from primary aluminum, which fluctuates based on market prices on exchanges such as the London Metal Exchange (LME) and the Shanghai Futures Exchange (SHFE).

• Die Manufacturing Cost – The cost of creating an extrusion die depends mainly on the profile’s maximum diagonal size; larger or more complex dies require more tooling material and precision machining, resulting in higher expenses.

• Extrusion Processing Cost – Profiles with larger cross-section diagonals require extrusion presses with higher tonnage, which increases production cost. Thin-wall or tight-tolerance designs may also raise extrusion difficulty.

• Heat Treatment Cost – Different tempers come with different costs. T5 is the most common and economical option. T6 temper requires faster quenching and added processing steps, making it more expensive.

• Surface Finishing Cost – Anodizing and powder coating are the most widely used finishes. Colored anodizing typically costs more than clear anodizing. Powder coating prices vary depending on the weather-resistance grade of the powder. PVDF coating offers the highest durability and UV resistance but comes at a significantly higher cost. Electrophoresis coating and wood-grain transfer (which requires pre-anodizing) also increase total finishing cost.

• Machining Cost – CNC machining, drilling, tapping, cutting, or welding costs depend on the complexity and quantity of the required operations. More precision or heavier machining increases the overall cost.
