Executive Sourcing Whitepaper: The 24-Inch Forged Metallurgy Paradigm

Analyzing structural dynamics, rotational inertia mitigation, and high-tensile 6061-T6 alloy application for heavy-duty electric and commercial platforms.

Aerospace-Grade 6061-T6 Monoblock

Forging at extreme hydraulic pressure (up to 12,000 tons) aligns the crystalline grain flow of virgin 6061-T6 aluminum billets along the contour of the rim. This dense grain alignment eradicates structural porosity, yielding ultimate tensile strengths exceeding 310 MPa and yield strengths beyond 275 MPa.

Continuous grain orientation across spoke intersections
Elongation ratings reaching 12% to 14% under destructive yield testing
Elimination of micro-cavitation common in conventional cast alloys

Dynamic Unsprung Weight Reduction

A standard 24-inch cast aluminum wheel routinely weighs between 22 kg and 26 kg. Through precision 5-axis CNC pocketing and FEA topological optimization, a 24-inch monoblock forged wheel reduces unit mass to 14.5 kg – 16.8 kg while providing load capacities up to 1,250 kg per corner.

28% to 35% reduction in rotational unsprung inertia
Substantial reduction in suspension cycle damping wear
Immediate improvements in EV watt-hour per kilometer efficiency

Modular 2-Piece & 3-Piece Architectures

For custom widebody offsets, extreme deep-lip requirements, and industrial armored vehicle tracks, modular forged construction combines forged centers with spun 6061 forged inner and outer barrels, sealed via automated liquid silicone gaskets and Grade 10.9 or titanium hardware.

Flexible millimeter-increment offset adjustments (ET -50 to +65)
Rapid serviceability with individual rim barrel replacement
Engineered lip depth options ranging from 1.5 inches to 7.0 inches

12,000T Hydraulic Forging Force

6061-T6 Virgin Aerospace Alloy

1,250 KG Peak Rated Corner Load

0.05 MM CNC Machining Tolerance

China Industry 4.0: Supply Chain Elasticity & Engineering Precision

Inside Shanghai Rimax Industry: Leveraging automated continuous metallurgical forging, 5-axis high-speed milling, and coordinate measuring machines (CMM) for zero-defect delivery.

Finite Element Analysis (FEA) Pre-Validation

Every custom 24-inch CAD profile is simulated in ANSYS for dynamic radial, rotational bending, and 13° impact forces before raw aluminum cutting begins. Our digital-twin engineering ensures that stress concentrations at spoke roots are completely eliminated while material is hollowed from low-stress nodes.

Result: Maximum structural stiffness with zero parasitic weight.

Simultaneous 5-Axis CNC Milling

Our machining floor utilizes precision Japanese DMG MORI and Makino 5-axis machining centers. Complex undercut geometry, concave angular drop-centers, and integrated weight-reduction pockets behind the spokes are machined in continuous cycles, maintaining axial runout within 0.18 mm and radial runout within 0.20 mm.

Tolerance consistency: Unmatched dynamic wheel balancing on balance rigs.

Integrated Heat Treatment & Quench Systems

Forged preforms undergo continuous solution heat treatment at 530°C, high-speed polymer-agitated immersion quenching to prevent internal thermal distortion, followed by automated artificial aging at 175°C for 8 to 12 hours. This produces the uniform T6 metallurgical temper throughout the entire 24-inch blank.

Durability metric: Brinell hardness reliably maintained between 95 and 110 HBW.

Technical Verification: Global Certification & Destructive Testing

Comparing international testing regimens to ensure our 24-inch custom forged series meets road compliance standards across North America, the European Union, Japan, and Australasia.

Technical & Sourcing FAQ: B2B Commercial Buyers

Key technical, logistic, and contractual answers for wheel importers, retail chains, and commercial engineering procurement leads.

What metallurgical advantages make 6061-T6 forged aluminum superior to low-pressure cast wheels in 24-inch sizing?

In 24-inch diameters, cast wheels suffer heavily from structural leverage: the long spoke spans act as torque levers under vehicle load, demanding thick, bulky cross-sections to pass JWL/VIA fatigue requirements. This inflates wheel mass to 22–26 kg. Forged 6061-T6 aluminum possesses a dense, continuous grain structure compressed under 10,000–12,000 tons of force, elevating yield strength by over 150% compared to cast A356.2 alloy. Consequently, forged 24-inch rims require less aluminum cross-sectional volume, reducing wheel weight to 14.5–16.8 kg while providing superior structural fatigue resistance, enhanced brake heat dissipation, and reduced rotational inertia.

What are your Minimum Order Quantities (MOQ) and production turnaround cycles for custom forged programs?

For custom forged orders with bespoke PCD, offset, center bore, and custom finishes, our MOQ starts at just 4 pieces (one car set) per custom design. For volume wholesale distributors and private-label container-load shipments, batches of 40 to 80 pieces unlock wholesale tier pricing. Production turnaround is typically 14 to 18 working days from final 3D CAD approval to finished packaging, with expedited 10-day rapid-prototyping air-shipment programs available for promotional or vehicle show builds.

Can Rimax engineer custom offsets and brake clearances for high-performance Big Brake Kits (BBK)?

Yes. Every order can be customized according to your specific brake profile. Buyers can provide 2D brake profile caliper drawings (distance from hub mounting face to caliper outer edge, caliper radius, and spoke clearance gap). Our engineering team imports your vehicle's CAD coordinate data into our 3D modeling environment, engineering backpad drops and spoke curvature angles to maintain a minimum 3.5 mm safety clearance between caliper face and inner spoke surfaces without requiring wheel spacers.

What structural and cosmetic warranties are extended on Kipardo / Rimax forged wheels?

Every Kipardo forged wheel manufactured by Shanghai Rimax Industry Co., Ltd. is backed by an industry-leading 5-year / 100,000 km structural warranty against material failure, spoke cracking, or internal metallurgical porosity under normal highway or specified off-road use. In addition, our high-durability surface finishes—including powder coats, diamond-cut faces, brushed tinted clears, and PVD finishes—carry a comprehensive 2-year warranty against bubbling, peeling, or premature corrosion.

How does the factory manage packaging, private-label branding, and international freight containerization?

Each wheel is protected with a waterproof plastic edge protector ring, scratch-resistant fleece cap covers, and non-abrasive PE foam wrapping, packed into high-density 5-ply corrugated export cartons capable of withstanding heavy stacking pressures. We offer comprehensive private-label OEM branding: your company logo, custom barcodes, and brand graphics can be printed on cartons, inner labels, and CNC-engraved directly on the wheel center caps and rims. Export documentation—including Commercial Invoices, Packing Lists, Certificates of Origin (Form E, CO, etc.), and mill test certs—is prepared by our in-house export compliance staff.
