5052 Aluminum Circle High Elongation Burr-Free Flat Disc 200-1200mm for Automotive Parts

Our 5052 aluminum circle is engineered for automotive parts manufacturers who demand the combination of high elongation formability, burr-free flat edges and documented international standard compliance in a single blank. Produced from high-purity 5052 alloy with strict process control from DC casting to precision blanking, this disc delivers consistent mechanical properties and surface quality for mass production stamping lines.

• High elongation up to 25% ensuring crack-free deep drawing, spinning and severe stamping
• Burr-free smooth cut edges and superior flatness for stable automatic press line feeding
• Manufactured and tested in compliance with ASTM B209, with mill test certificates available
• Excellent fatigue resistance and corrosion resistance for automotive service conditions
• Clean surface quality suitable for painting, anodizing and coating processes
• Uniform hardness distribution across the disc for predictable forming results
• Batch traceability with full chemical composition and mechanical property reports

This 5052 aluminum circle is widely used in the automotive industry for manufacturing stamped and formed components:

• Wheel covers and hub caps: excellent formability allows deep embossing and decorative patterns without cracking
• Heat shields and engine bay protection panels: high temperature resistance and fatigue strength ensure long service life under thermal cycling
• Brackets, mounting plates and structural stampings: consistent mechanical properties support high-speed automatic stamping production
• Gaskets and sealing components: clean burr-free edges prevent damage to mating surfaces and sealing rings
• Fuel tank and fluid reservoir blanks: superior corrosion resistance meets demanding under-hood environments
• Interior and exterior trim parts: clean surface quality is ready for painting, anodizing, brushing or chrome-look finishing

Beyond automotive applications, this alloy combination also serves marine components, pressure vessels, kitchenware spinning and general industrial fabrication where strength and formability must coexist.
