Standard: GB / T 3196-1982 Features and Scope: 2A10 aluminum alloy for the rivets. High shear strength, annealing, just quenching, aging and thermal state are required to have sufficient plasticity riveting rivets; riveting with after quenching and aging, the time limit is not heat-treated after the riveting process. Aluminum 2A10 and 2A11 same weldability, corrosion stability and 2A01,2A11 same rivets. Heated above 100 ℃, intergranular corrosion tendency. Chemical composition: Al Al: margin silicon Si: ≤0.25 Copper Cu: 3.9 ~ 4.5 Magnesium Mg: 0.15 ~ 0.30 Zinc Zn: ≤0.10 Manganese Mn: 0.30 ~ 0.50 Titanium Ti: ≤0.15 iron Fe: 0.000 ~ 0.200 Note: Single : ≤0.05; Total: ≤0.10 mechanical properties: shear strength τ (MPa): ≥245 Note: The natural aging after solution heat treatment wire to a substantially steady-state shear properties of the sample size: wire diameter ≥8.0 heat treatment specification: fully annealed : heating 390 ~ 430 ℃; with the effective thickness of different materials, holding time 30 ~ 120min; with 30 ~ 50 ℃ / h speed with furnace cooling at 300 ℃ to, and then cooled. 2) rapid thermal annealing: heating 350 ~ 370 ℃; with the effective thickness of different materials, holding time 30 ~ 120min; air cooling. 3) quenching and aging: hardening 510 ~ 520 ℃, water-cooled; artificial aging 70 ~ 80 ℃, 24h, air-cooled; natural aging at room temperature for 240h. Status: rivet aluminum and aluminum alloy wire (≥8.0mm, T4 state)
