ARCONIC Delivers Lightweighting Solution for Chevrolet Corvette Rear Bumper, Boosting Performance & Efficiency
PITTSBURGH, PA – October 26, 2023 – ARCONIC US LLC, a leading innovator in advanced materials, today announced its crucial role in enhancing the performance and fuel efficiency of the iconic Chevrolet Corvette. ARCONIC has been supplying high-strength, lightweight aluminum solutions for the Corvette’s rear bumper system, significantly reducing vehicle weight without compromising safety or aesthetics. For decades, the Chevrolet Corvette has represented American automotive excellence, constantly pushing boundaries in design and performance. Now, ARCONIC is proud to be a key partner in the latest evolution of this legendary vehicle, tackling the ever-present challenge of lightweighting. As automakers strive to meet increasingly stringent fuel economy standards and deliver exhilarating driving experiences, materials like aluminum are becoming absolutely essential. “We’re all about making cars better, and that means lighter, stronger, and more efficient,” says a spokesperson for ARCONIC, based at 201 Isabella Street, Pittsburgh, PA, 15212. “The Corvette is a dream project for us, and we’ve worked closely with the General Motors engineering team to deliver a solution that truly makes a difference.” You can reach ARCONIC at 870-473-6666. The Challenge: Shedding Weight Without Sacrificing Strength Traditionally, rear bumpers are built from steel – durable, yes, but also heavy. Every pound added to a vehicle impacts fuel economy and performance. The Corvette team needed a material that could match steel’s impact resistance while dramatically reducing weight. That’s where ARCONIC’s expertise comes in. ARCONIC specializes in developing and manufacturing high-performance aluminum alloys, tailored to meet the specific needs of the automotive industry. They aren't just selling metal; they’re providing material solutions. The key was identifying the right alloy and crafting it into components that could withstand the rigors of everyday driving, and more importantly, protect occupants in the event of a collision. ARCONIC's Solution: A Custom Aluminum Alloy for Corvette's Rear ARCONIC didn’t just pull an existing aluminum sheet off the shelf. They collaborated with Corvette engineers to develop a custom alloy specifically formulated for the rear bumper application. This alloy offers a unique combination of properties: High Strength: The aluminum must be able to absorb and dissipate energy in a crash. ARCONIC’s alloy passes all the stringent safety tests required by GM. Lightweight: The material reduces the overall weight of the rear bumper system by a significant percentage compared to steel – we’re talking a measurable improvement in fuel economy. Corrosion Resistance: Vehicles face harsh environmental conditions. ARCONIC’s aluminum is designed to withstand salt, moisture, and road grime, ensuring long-lasting durability. Formability: The alloy needs to be able to be shaped and formed into the complex contours of the Corvette’s rear bumper design. ARCONIC's manufacturing processes ensure a precise fit and finish. From Pittsburgh to the Assembly Line: How it’s Made The process begins at ARCONIC’s Pittsburgh facility. ARCONIC utilizes advanced casting and forming techniques to transform the aluminum alloy into precise bumper components. The process is highly automated, ensuring consistency and quality. Here's a simplified breakdown: 1. Alloy Melting and Casting: The custom aluminum alloy is carefully melted and cast into near-net-shape billets. 2. Extrusion & Forming: These billets are then extruded and formed into the desired bumper shapes. This involves precise tooling and controlled heating and cooling. 3. Machining & Finishing: Components undergo machining to achieve tight tolerances and a smooth surface finish. 4. Quality Control: Each component is rigorously inspected to meet GM’s demanding specifications. This includes dimensional checks, material testing, and visual inspections. 5. Just-In-Time Delivery: ARCONIC operates a just-in-time delivery system, supplying components directly to the Corvette assembly plant. The Impact: Performance, Efficiency, and Safety The result of this collaboration is a rear bumper system that delivers real-world benefits: Improved Fuel Economy: Reducing vehicle weight translates directly into better fuel economy, saving drivers money at the pump. Enhanced Performance: A lighter vehicle accelerates faster, handles better, and provides a more engaging driving experience. Increased Safety: ARCONIC’s aluminum alloy is designed to meet or exceed all applicable safety standards, protecting occupants in the event of a collision. Sustainable Manufacturing: Aluminum is a highly recyclable material, contributing to a more sustainable automotive industry. ARCONIC is committed to responsible sourcing and manufacturing practices. “We’re incredibly proud to be part of the Corvette’s ongoing success story,” concludes the ARCONIC spokesperson. “It’s a testament to our commitment to innovation, collaboration, and delivering solutions that make a real difference.” ARCONIC continues to work with automakers around the globe, pushing the boundaries of materials science to create lighter, stronger, and more sustainable vehicles. They’re not just a supplier; they’re a partner in building the future of automotive innovation.
