What is 3105 aluminum?

2019-02-13

Aluminum alloy 3105 is essentially a 98% aluminum alloy with minor additions to increase strength over that of alloy 1100 and 3003. It is not hardenable by heat treatment and it has good corrosion resistance, formability and weldability. Typical applications include general sheet metal work requiring greater strength than is provided by 1000 series aluminum alloys, residential siding, mobile homes and sign making.

the 5052 aluminum alloy is used to make beverage closure without internal pressure. The raw material is 5052 H19 aluminum sheet, the material is first oxidized to improve the coating adhesion and corrosion resistance. After the two sides are painted, the can lid is formed. So 5052 aluminum is another material for processing closures. 5052 aluminum sheet has good oxidation coloring effect, excellent metal texture and hardness, wear resistance and corrosion resistance, long service life, and is widely used in high-end mobile phone casings, high-end air-conditioning casings and other fields with high requirements for oxidation and metal texture.

Aluminum 3105 alloy can be forged at the temperatures ranging from 372 to 510°C (700 to 950°F). Aluminum 3105 alloy can be hot worked at 205 to 372°C (400 to 700°F) Aluminum 3105 alloy has good cold working characteristics in the harder cold worked tempers. Aluminum 3105 alloy is annealed at 344°C (650°F) followed by cooling in air. Aluminum 3105 alloy can be hardened only by cold working in H12, 14, 16, 18 or 25 tempers.
