RSC supplies aluminum rod, plate, and extrusion for automotive components pre-matched to each part’s structural role – formable grades for body panels, high-strength grades for wheels and crash beams, and weldable structural grades for engine mounts and brackets. Automotive builders sourcing across a mixed bill of materials get one supplier who quotes the correct grade per component, not one general-purpose alloy carried across body, chassis, and trim parts alike.
Sourcing Risk
Automotive programs run body, chassis, and trim components through very different qualification paths – a crash beam has to pass impact testing, a body panel has to pass forming and finish inspection, an engine mount has to hold up under vibration and heat. A supplier that ships a convenient general-purpose grade instead of the alloy matched to each qualification path passes that mismatch downstream as a failed crash test, a cracked panel during stamping, or a mount that fatigues ahead of schedule. RSC quotes each automotive component against its qualification requirement at order stage, before it becomes a validated part.
If Overlooked
What an Alloy Mismatch Costs in Automotive Programs – and How RSC’s Grade Matching Prevents It
Automotive alloy mismatches typically surface during crash testing, stamping trials, or vehicle-level durability testing – all expensive stages to discover a materials problem. RSC’s per-component grade matching is built to catch this earlier:
- Body panels stamped from a poorly formable alloy can crack or wrinkle during the forming process – RSC supplies 5754 for these components specifically for its forming performance, keeping panel scrap rates down on the stamping line.
- Wheels and crash beams built from an under-specified alloy risk failing impact or load testing – RSC quotes 7075-T6 for these high-stress components, selected for the strength margin crash-rated parts need.
- Engine mounts and structural brackets in a weld-sensitive high-strength alloy can lose strength at the joint under vibration and heat cycling – RSC supplies 6061-T6 for these components because it holds weld strength through sustained thermal and vibration load.
- Extruded trim and frame components specified in an alloy with poor extrudability drive up tooling cost and surface defects – RSC quotes 6063-T5 for trim and extruded frame parts, chosen for extrusion quality and finish.
Each of these risks traces back to alloy grade selected for convenience instead of the component’s qualification path – which is the specific gap RSC’s per-component grade matching is built to close before your parts reach testing.

How RSC Supplies Aluminum for Automotive Applications
RSC supplies automotive components across the alloy grades matched to qualification path – 5754 for formed body panels, 7075-T6 for wheels and crash-rated components, 6061-T6 for engine mounts and structural brackets, and 6063-T5 for extruded trim and frame parts. Every batch is produced under an ISO 9001 quality management system, with products manufactured to ASTM B209, EN, and GB international standards, so the alloy specified for your part is the alloy verified in the batch you receive.

Confirm Alloy Grade Before Your Parts Reach Testing
Automotive alloy selection is far cheaper to correct at the quoting stage than after a part has entered crash, stamping, or durability testing.
