ENGINEERING PROCESS

HOW FORGED WHEELS ARE MADE AT RRT

A controlled, high-pressure forming process that prioritizes material density, structural integrity, and precise engineering tolerances.

BUILD YOURS TODAY

Forged wheels are manufactured through a controlled, high-pressure forming process that prioritizes material density, structural integrity, and precise engineering tolerances. At RRT Forged, the process is designed to deliver wheels that are lighter, stronger, and more consistent than cast alternatives.

Aerospace-Grade Aluminum
01

Aerospace-Grade Aluminum

The process begins with a solid billet of high-quality aluminum alloy, typically 6061-T6. This alloy is chosen for its balance of strength, fatigue resistance, and machinability. Unlike cast wheels, no molten metal is poured into a mold. The aluminum starts as a dense, uniform block with no inherent porosity.
High-Pressure Forging
02

High-Pressure Forging

The billet is heated to a controlled temperature and driven into a forging press. Several thousand tons of pressure compress the metal and force the grain structure to flow along the wheel's design lines. Rather than forging the final shape in one hit, the press first produces a near-net preform: barrel and center structure roughed in, material distribution even, internal stress kept low before the next stage.
Heat treatment
03

Heat treatment

Once forged, the preform goes through heat treatment to bring the 6061 alloy up to its full T6 temper. Solution heat treating followed by controlled aging raises tensile strength, yield strength, and fatigue resistance well beyond the as-forged state. This is what lets the wheel take repeated load cycles, hard braking, and aggressive cornering without the metal fatiguing over time.
Design and Optimisation
04

Design and Optimisation

With the alloy's mechanical properties locked in, engineers move to CAD and FEA modeling to finalize the design: spoke geometry, hub bore, bolt pattern, offset, backspacing, and weight-optimization pockets. Because the forged blank already carries high structural integrity, engineers can pull material out in the right places without compromising strength. This step decides exactly where the CNC machine needs to cut.
Precision CNC Machining
05

Precision CNC Machining

A 5-axis CNC machine cuts the heat-treated blank to the specification set in the design stage. Cutting fluid keeps tool and material temperature stable through the pass. This is where the near-net preform becomes the finished wheel: exact bolt pattern, exact offset, exact spoke profile, tolerances held tight enough for OEM-fitment accuracy.
Surface Treatment and Finishing

Surface Treatment and Finishing

The final stage is surface finishing. Depending on the specification, this may include brushed or polished finishes, powder coating, custom paint, and clear coating for corrosion resistance. Each finish is applied with durability and consistency in mind, not just appearance.

WHY FORGED WHEELS ARE DIFFERENT

Compared to cast wheels, forged wheels offer structural advantages that matter for performance and safety.

Higher Strength-to-Weight Ratio

Forged wheels are significantly stronger while weighing less than cast alternatives.

Improved Impact Resistance

The dense grain structure from forging resists cracking and deformation under stress.

Reduced Unsprung Mass

Lighter wheels improve acceleration, braking, and suspension response.

More Precise Fitment

CNC machining from forged blanks allows exact offsets and bolt patterns.

For performance vehicles and high-load applications, forging is not a cosmetic upgrade. It is a structural one.

FAQ

FREQUENTLY ASKED QUESTIONS

Find answers to common questions about forged wheels below

Forged wheels are made from a solid aluminum billet that is shaped under extreme pressure. This process compresses the metal grain structure, creating a wheel that is stronger, lighter, and more durable than traditional cast wheels.

Cast wheels are made by pouring molten aluminum into a mold. This can introduce air pockets and inconsistencies in the metal. Forged wheels, by contrast, start as a solid billet and are compressed under high pressure, resulting in superior strength and a lower weight.

Yes. While they are more expensive than cast wheels, the benefits include reduced weight for better performance, higher strength and impact resistance, long-term durability, and ability to optimize design for fitment and aesthetics.

Absolutely. The high strength-to-weight ratio of forged wheels makes them ideal for high-performance applications, track use, and vehicles that experience heavy loads or high cornering forces.

Forged wheels can be 15-25% lighter than cast wheels of the same size. This reduction in unsprung mass improves acceleration, braking, and cornering performance.

Yes. RRT Forged wheels can be CNC-machined to exact specifications, allowing custom spoke designs, offsets, finishes, and paint options. Each wheel is engineered to maintain strength while achieving the desired aesthetics.
