What are the fundamental properties of 1060 aluminum coil?
1060 aluminum coil is a commercially pure aluminum alloy with a minimum 99.6% aluminum content, offering excellent corrosion resistance. It has high thermal and electrical conductivity, making it suitable for electrical applications. The alloy is soft and ductile, with a tensile strength of around 70–110 MPa, ideal for forming operations. It can be easily welded and brazed without specialized techniques. Additionally, its reflective surface makes it useful for decorative and lighting applications.
What are the typical applications of 1060 aluminum coils?
Electrical industries use 1060 coils for busbars, transformer windings, and capacitor foils due to its conductivity. The food and chemical industries employ it for storage tanks and piping because of its non-reactive surface. It's widely used in signage, nameplates, and architectural trim for its finish and malleability. The packaging industry utilizes it for foil stock and laminates. Its low cost and workability make it a popular choice for general fabrication.
How does 1060 aluminum compare to 1100 alloy?
Both alloys are nearly pure aluminum, but 1100 has slightly higher purity (99.0% vs. 99.6% for 1060). 1060 offers marginally better conductivity and corrosion resistance due to fewer impurities. Mechanical properties are similar, with both being soft and formable. 1100 is more common in the U.S., while 1060 is standardized in China (GB/T 3880). Surface treatment options (e.g., anodizing) are identical for both alloys.
What tempers are available for 1060 aluminum coils?
O-temper (annealed) provides maximum softness for deep drawing and intricate forming. H12, H14, and H16 tempers offer incremental increases in hardness through strain hardening. H18 temper delivers the highest strength but reduced ductility. Custom tempers can be produced to balance formability and strength for specific applications. The choice of temper depends on the required balance between workability and mechanical properties.
What are the key considerations when welding 1060 aluminum?
Use 1100 or 4043 filler wire to match the base metal's purity and avoid cracking. Clean surfaces thoroughly to remove oxides before welding. Employ TIG or MIG welding with argon shielding gas for best results. Control heat input carefully to prevent warping due to the alloy's high thermal conductivity. Post-weld annealing may be necessary to restore ductility in cold-worked tempers.
