What is forged aluminium? Forged aluminium is aluminum that has been shaped under immense pressure and controlled temperature to create components with superior strength, durability, and grain structure. Unlike cast aluminum, the forging process aligns the metal’s grain flow with the part’s contours, significantly enhancing mechanical properties and eliminating internal defects. This comprehensive guide explores the forging process, benefits, applications, and why MAIKONG’s aluminum forging services deliver exceptional quality for demanding industries.

The Forging Process: How What is Forged Aluminium Becomes Reality
The aluminum forging process transforms raw aluminum alloys into high-performance components through controlled deformation. Understanding this process is essential to appreciating why forged aluminum delivers superior performance compared to other manufacturing methods.
The complete aluminum forging process from raw billet to finished component
Key Stages in the Aluminum Forging Process
- Billet Preparation: Raw aluminum alloy is cut to the appropriate size and weight for the desired component.
- Heating: The billet is heated to a specific temperature (typically 750-950°F depending on the alloy) to increase plasticity.
- Forging: The heated aluminum is placed between dies and subjected to immense pressure, forcing it to conform to the die shape.
- Trimming: Excess material (flash) is removed from the forged part.
- Heat Treatment: The component undergoes controlled heating and cooling to achieve desired mechanical properties.
- Finishing: Final machining, surface treatments, and quality inspections complete the process.
Types of Aluminum Forging Processes
Open-Die Forging
Material is compressed between flat or simply shaped dies that don’t completely enclose it. Ideal for large, simple shapes with excellent mechanical properties.
Closed-Die Forging
Material is shaped within cavity dies that impart a specific shape. Provides better dimensional control and is suitable for complex geometries.
Precision Forging
Advanced process that creates near-net-shape components with minimal need for secondary machining. Offers tight tolerances and excellent material properties.

Frequently Asked Questions About Forged Aluminium
Our customers often have questions about forged aluminium and our manufacturing processes. Here are answers to some of the most common inquiries we receive.
What makes forged aluminum stronger than cast aluminum?
Forged aluminum is stronger than cast aluminum due to three primary factors: 1) The forging process creates a refined, dense grain structure with minimal porosity; 2) The directional grain flow follows the contours of the part, concentrating strength where needed; and 3) The mechanical working during forging eliminates internal defects that can serve as stress concentration points. These factors combine to provide superior tensile strength, fatigue resistance, and impact toughness compared to cast aluminum.
What aluminum alloys are best for forging?
The best aluminum alloys for forging depend on the specific application requirements. The most commonly forged aluminum alloys include:
- 2xxx series (Al-Cu): Such as 2014 and 2024, offering high strength and good machinability
- 6xxx series (Al-Mg-Si): Including 6061 and 6082, providing a good balance of strength, corrosion resistance, and formability
- 7xxx series (Al-Zn): Like 7075, delivering the highest strength among aluminum alloys
At MAIKONG, we help customers select the optimal alloy based on mechanical requirements, environmental conditions, manufacturing considerations, and cost constraints.
What is the difference between forged aluminum and extruded aluminum?
Forged aluminum and extruded aluminum differ in their manufacturing processes and resulting properties:
- Forging: Involves compressive force to shape heated aluminum between dies, creating components with superior strength, refined grain structure, and directional properties
- Extrusion: Involves pushing heated aluminum through a die to create long profiles with consistent cross-sections, offering good strength in the longitudinal direction but less control over grain structure
Forging is typically used for discrete, high-strength components with complex 3D geometries, while extrusion is ideal for long, uniform cross-section products like profiles, tubes, and bars.
What are the limitations of aluminum forging?
While aluminum forging offers many advantages, it does have some limitations:
- Geometric Complexity: Very complex shapes with deep recesses or thin sections can be challenging to forge
- Tooling Costs: Initial die costs can be high, especially for low-volume production
- Size Limitations: Very large components may require specialized equipment
- Minimum Order Quantities: May not be economical for extremely small production runs
At MAIKONG, we work closely with customers to overcome these limitations through innovative design approaches, optimized tooling, and efficient production planning.
