Latest Patents

One of his latest patents focuses on an aluminum alloy and corresponding heat treatment process applied to manufacture aluminum/steel cladding plates resistant to high-temperature brazing. This innovation involves alloying the aluminum part with 0.76% to 0.78% silicon and 0.055% to 0.10% erbium by weight, with the remainder being aluminum and some unavoidable impurities. The steel component is made from 08Al steel. After undergoing cold rolling with a deformation of 55% ± 2%, the aluminum/steel cladding plates are annealed at temperatures between 510°C and 535°C for varying durations. This process not only enhances the interface strength of the cladding plates but also ensures they meet the necessary mechanical properties for further processing.

Another significant patent by Wen details a heat treatment process for high-Mg Er-containing aluminum alloy cold-rolled plates that are resistant to intergranular corrosion. The composition of this alloy includes 5.8% to 6.8% magnesium, 0.4% to 0.8% manganese, 0.15% to 0.25% erbium, and 0.15% to 0.25% zirconium, with impurities kept below 4%. The cold-rolled plates undergo stabilization annealing at temperatures between 235°C and 245°C for 3.5 to 4 hours, followed by air cooling to room temperature. This innovative process significantly improves resistance to intergranular corrosion without substantially reducing the alloy's strength.
