Why Choose Haomei 4 Inch Aluminum Discs?
Choosing the right aluminum disc directly affects forming performance, production efficiency and the final appearance of finished products. Haomei Aluminum supplies 4 Inch Aluminum Discs with consistent material quality, accurate dimensions and reliable surface performance for cookware, lighting, stamping and industrial applications.
Reliable Aluminum Grades for Different Applications
Haomei provides 1050, 1060, 1100 and 3003 aluminum discs to meet different forming and strength requirements. Soft alloys such as 1050, 1060 and 1100 offer excellent ductility for deep drawing, spinning and cookware-related production.
For applications that require better mechanical strength, such as equipment covers, industrial stamped parts and sign blanks, 3003 aluminum discs provide a balanced combination of strength, corrosion resistance and formability.
Precise Size Control for Efficient Processing
A standard 4 inch aluminum disc has a diameter of 101.6 mm. Haomei Aluminum controls diameter tolerance, thickness accuracy and flatness during production to ensure smooth performance in stamping and spinning lines.
Customized options are available according to customer requirements, including specific diameter sizes, thickness ranges, alloy grades, tempers and surface finishes for OEM manufacturing projects.
Clean Surface and Export-Ready Quality
Surface quality is critical for visible aluminum components. Haomei 4 Inch Aluminum Discs are carefully inspected to minimize scratches, oil marks, edge burrs and other defects that may affect further processing.
With controlled production and protective packaging, our aluminum discs are suitable for international shipments and applications such as lamp reflectors, decorative parts, cookware accessories and precision stamped components.
Recommended Aluminum Alloys for 4 Inch Aluminum Discs
The right aluminum alloy plays an important role in forming quality, surface appearance and final product performance. Haomei Aluminum supplies 4 Inch Aluminum Discs in multiple alloy grades, allowing customers to select suitable materials according to deep drawing, spinning, stamping and strength requirements.
1050 Aluminum Disc
1050 aluminum disc is widely used where excellent formability, corrosion resistance and surface quality are required. With high aluminum purity and good ductility, it performs well in lighting reflectors, decorative components, household products and general stamping applications.
1060 Aluminum Disc
1060 aluminum disc offers outstanding elongation and smooth forming performance, making it a practical choice for deep drawing and spinning processes. It is commonly used for small cookware parts, lamp covers, electrical components and other products requiring consistent forming results.
1100 Aluminum Disc
1100 aluminum disc combines good workability with a clean surface finish. It is suitable for applications such as lighting reflectors, nameplates, decorative panels and stamped aluminum parts where appearance and easy processing are important.
3003 Aluminum Disc
3003 aluminum disc provides higher strength than 1000-series aluminum due to manganese addition while maintaining good formability and corrosion resistance. It is often selected for cookware, industrial covers, traffic signs and stronger stamped components.
Haomei Aluminum can provide customized aluminum discs in different alloys, thicknesses and tempers. For customers requiring larger diameter aluminum circles, please explore our 12 Inch Aluminum Disc and 24 Inch Aluminum Disc product pages.
