6061 aluminum sheet is a high-quality alloy product produced by heat treatment and pre-stretching. Although its strength cannot be compared with 2000 series alloy or 7000 alloy series, the composition of 6061 aluminum alloy is mainly Mg and Si, so 6061 aluminum sheet exhibits excellent processing performance, excellent weldability and electroplating, good corrosion resistance, high toughness and other characteristics. It is worth mentioning that the dense structure of 6061 aluminum sheet does not deform after processing. In addition, 6061 aluminum alloy can be easily polished, colored film, etc., and its oxidation effect is excellent. Knowing this, it is not difficult to find that 6061 aluminum sheet is a suitable material for the manufacture of precision machinery, automotive wheels, 3C products, mobile phone shells, molds, trolley cases, alloy doors and windows.
1. Workability. The main temper of 6061 aluminum sheet are T4, T6 and T651. Among them, the 6061-T6 aluminum sheet has a large internal stress, which may cause deformation during processing, so the 6061-T651 aluminum sheet is more suitable for product processing.
2. Mechanical Characteristics. The ultimate tensile strength of 6061 aluminum sheet is more than 205 MPa, the compressive yield strength is 55.2 MPa, the elastic modulus is 68.9 GPa, the bending ultimate strength is 228 MPa, and the bending yield strength is 103 MPa, the strength is higher than 6063 alloy sheet.
3. Comprehensive Characteristics. In short, 6061 aluminum sheet has excellent characteristics such as excellent processability, good corrosion resistance, high toughness, excellent weldability and electroplating, easy coating film, and excellent oxidation effect.
It is widely used in mobile phone card slot (suitable for 5G mobile phone), buttons, computer bracket, computer shell and other 3C field, as well as pull rod case, aluminum furniture, door/door handle, SMT, PC board solder carrier and so on.(White surface / bright surface, no milling surface required, saving cost. )
It is widely used in underwear molds, shoe molds, precision machining, passenger car decorative plates / checker plates, automobile chassis protection parts, automobile four doors and two covers, automobile wheels, automobile seats, etc. (Internal stress is eliminated and cutting is not deformed.
