Introduction of H temper of aluminum foil and characteristics of aluminum

The biggest feature of aluminum foil is its light weight and wide range of uses, suitable for aviation, construction, decoration, industry and other industries. Aluminum is very cost-effective, and its electrical conductivity is second only to that of copper, but the price is much cheaper than that of copper, so many people now choose aluminum as the main material for wires.

1060, 3003, 5052 are several commonly used aluminum foils, which are widely used in thermal insulation materials, decoration materials, molds and other industries. Different aluminum foils have different temper s and process properties. Now let’s introduce the meaning and difference of the common temper s H18, H24 and H32 in the aluminum foil.

H in the above temper refers to work hardening to improve the strength of the aluminum foil, and the two Arabic numerals after H are added (called HXX state). The 1st digit after the H represents the basic handler that gets the temper,

  • H1: refers to the work-hardened temper.
  • H2: temper of work hardening and incomplete annealing.
  • H3: Work-hardened and stabilized temper.

The temper of the aluminum foil is different and the performance is also different.

Features of H temper aluminum foil:

1. Machinability: Aluminum has excellent machinability. In deformed aluminum alloys and cast aluminum alloys, the machinability changes considerably in various tempers after production.

2. Formability: The specific tensile strength, yield strength, ductility and corresponding work hardening rate govern the change in allowable deformation.

3. Forgeability: Aluminum alloys can be forged into a wide variety of shapes and forgings. Linking Aluminum can be joined by a variety of methods, including welding, resistance welding, brazing, soldering, bonding, and mechanical methods such as riveting and bolting.

4. Recyclability: Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.
