Chemical Composition Standards
Aluminum Alloy 1060 (per ASTM B209 / GB standards):
Aluminum coil DC CC50 1060 3003 O H14 presents a fascinating array of material properties and processing challenges. The "DC" denotes a direct-chill casting process, usually resulting in a coarser grain structure compared to other casting methods. This impacts its formability; while 1060 (high purity) and 3003 (manganese alloyed) offer good ductility, the DC casting might necessitate more careful control during stamping or bending operations to prevent cracking or surface defects. The "CC50" likely refers to a specific coil configuration or quality standard within our factory, influencing aspects like coil width, thickness tolerances, and surface finish requirements. these parameters is crucial for ensuring downstream processes like slitting, winding, and final product fabrication run smoothly. Variations in these specifications can significantly impact production efficiency and final product quality.
Furthermore, the temper designation "O H14" is critical. "O" indicates an annealed state, meaning the aluminum is relatively soft and malleable, ideal for deep drawing applications. However, the "H14" suggests a subsequent strain hardening process, offering increased strength and springback resistance. This combination implies a balance between formability and strength, making it suitable for specific applications where a degree of hardness is needed but excessive stiffness is detrimental. The precise degree of hardening achieved during the H14 temper will depend on many variables including the specific processing parameters employed during
