Quick Recap
1. Quick Answer
Yes — JIMAFOR forged aluminum components are a must-have for automakers in the lightweight trend: they’re 3x lighter than steel (retaining 90% strength), boost EV range by 7-12%, and cut production emissions by 9% — all while passing 5-star crash tests. Backed by 18 years of aluminum forging expertise and IATF 16949 certification, these components help 50+ global OEMs balance weight reduction, safety, and compliance seamlessly.
2. Why Lightweight = Non-Negotiable for Automakers
Lightweighting has shifted from a competitive edge to a mandatory requirement for automakers, driven by converging global regulatory pressures and consumer expectations. The dual mandate of reducing carbon emissions and extending EV range leaves no room for compromise — and automakers must achieve these goals without sacrificing vehicle safety, durability, or affordability. Forged aluminum emerges as the only material that meets all these conflicting demands effectively.
2.1 Emissions & EV Range Pressures
The correlation between vehicle weight and operational efficiency is direct and impactful, shaping market competitiveness and regulatory compliance for both gasoline and electric vehicles:
-
Gasoline Vehicles: Fuel Efficiency & Emissions Cuts — A 10% reduction in vehicle weight translates to a 6-8% improvement in fuel efficiency. This is critical for meeting stringent global emissions targets, such as the EU’s 2030 mandate to cut new vehicle CO₂ emissions by 55% compared to 2021 levels. For automakers, every kilogram of weight saved lowers non-compliance risks and costly penalties.
-
Electric Vehicles: Range Anxiety Mitigation — EV consumers rank range anxiety as their top concern, and weight is a primary limiting factor for battery efficiency. A 10% weight reduction delivers a 5-7% longer EV range — a tangible gain that differentiates models in a crowded market. Forged aluminum components address this pain point without requiring expensive battery capacity upgrades, optimizing both cost and performance.
3. Forged Aluminum: The “Must-Have” Solution
While alternatives like cast aluminum, carbon fiber, or high-strength steel exist, forged aluminum stands out as the “must-have” lightweight solution for automakers. JIMAFOR’s 18 years of aluminum forging expertise ensures our components deliver consistent performance, safety, and cost benefits that align with high-volume OEM production needs.
3.1 Key Advantages for Automakers
JIMAFOR forged aluminum components offer three core advantages that solve automakers’ most pressing challenges, from safety to cost optimization. Each feature is engineered to deliver measurable value in production and real-world operation:

Why It Matters for Automakers
|
|
Strength-to-weight ratio (3x lighter than steel, 90% strength)
|
Density of 2.7g/cm³ (vs. steel’s 7.8g/cm³) with tensile strength up to 350MPa for 6061-T6 forged aluminum, retaining 90% of steel’s structural capability.
|
Extends EV range by 7-12%, cuts fuel consumption and emissions for gasoline cars, and maintains handling agility without compromising safety.
|
|
No internal pores (forged, not cast)
|
High-pressure forging eliminates pores, bubbles, and micro-cracks common in cast aluminum, creating a dense, uniform grain structure that absorbs 2x more impact energy.
|
Ensures compliance with 5-star crash safety ratings, reducing accident risks and suspension-related warranty claims for OEMs.
|
|
40% less material waste
|
Forging process generates 40% less waste than machining or cast aluminum, with scalable production to lower unit costs for high-volume orders.
|
Reduces annual material costs by $2.3M for automakers producing 100,000 units/year, with no sacrifice to quality or production speed.

3.2 Real-OEM Case Study
A leading German EV manufacturer partnered with JIMAFOR to lightweight its flagship model, seeking to enhance range without increasing battery size or compromising crash safety. Leveraging our aluminum forging expertise and IATF 16949-compliant production, we delivered a tailored solution with measurable results:
Project Scope
The automaker aimed to replace steel chassis components with lightweight alternatives to reduce vehicle weight, extend EV range by 10%+, and lower production carbon emissions — all while retaining its 5-star crash safety rating.
JIMAFOR Solution
We replaced 80% of the vehicle’s steel chassis parts (including control arms, suspension links, and subframe brackets) with 6061-T6 forged aluminum components. Each part was optimized via CAD/CAM simulation to balance weight reduction and structural strength, then produced in our IATF 16949-certified factory.
Measurable Results
-
Vehicle weight was cut by 16kg, a critical gain for battery efficiency.
-
EV range increased from 550km to 616km — a 12% improvement that eliminated range anxiety for consumers.
-
Production carbon emissions reduced by 9%, thanks to lower material waste and energy consumption in component manufacturing.
-
The model retained its 5-star crash safety rating, with forged aluminum components absorbing 22% more impact energy than the previous steel parts.
4. Common Procurement Questions: Professional Answers by JIMAFOR
Drawing on 18 years of partnering with 50+ global automotive OEMs, JIMAFOR addresses key procurement concerns, helping automakers navigate aluminum forging solutions, balance cost and performance, and ensure supply chain compliance.
-
Q1: What aluminum alloys do you recommend for automotive chassis components, and how to choose? A1: We primarily use 6061-T6 and 7075-T6 forged aluminum for automotive applications. 6061-T6 is ideal for chassis, suspension, and subframe parts — offering the best balance of strength, lightweight, and cost efficiency (used by 90% of our OEM clients). 7075-T6 is stronger (tensile strength up to 540MPa) but higher-cost, suited for high-performance or racing vehicles. Our engineering team recommends alloys based on your component’s load requirements, safety standards, and budget.
-
Q2: Can your forged aluminum components integrate with our existing production lines and meet IATF 16949? A2: Yes. Our factory is fully IATF 16949 certified, and we align production processes with OEM assembly line specifications. We provide complete PPAP and APQP documents, and our components are designed with standard ±0.03mm tolerances (customizable to your tooling). We also offer on-site technical support to ensure seamless integration.
-
Q3: What is the lead time for mass production of forged aluminum components? A3: For standard components (e.g., control arms), mass production (10,000+ pieces/month) takes 3-4 weeks. For customized parts, lead time is 4-6 weeks (includes prototyping, testing, and setup). We maintain stock of 6061 aluminum billets to accelerate production, and offer expedited lead time (2-3 weeks) for urgent OEM orders.
-
Q4: How do you ensure consistent quality across high-volume batches? A4: We implement a three-layer QC system: incoming material testing (aluminum billet purity), in-production 3D scanning (tolerance checks), and final testing (impact resistance, tensile strength). Every batch comes with a quality report, and our defect rate for OEM partners is consistently below 0.01%.
-
Q5: What’s the total lifecycle cost comparison vs. steel components? A5: While forged aluminum has a 10-15% higher initial cost, total lifecycle cost is 20-25% lower. Savings come from material waste reduction ($2.3M/year for 100k units), lower emissions penalties, and reduced warranty claims. We provide a tailored cost-benefit analysis for each OEM client.
5. Quick Recap
JIMAFOR forged aluminum components check all boxes for automakers in the lightweight trend: they’re 3x lighter than steel (retaining 90% strength) for enhanced EV range and fuel efficiency, pore-free for 5-star crash safety, and 40% more material-efficient for cost savings. Backed by 18 years of aluminum forging expertise and IATF 16949 certification, these components support 50+ global OEMs in meeting emissions regulations, reducing weight, and delivering safer, more efficient vehicles — making them a non-negotiable choice in automotive lightweighting.
