Latest Patents

Ozeki holds a patent for an aluminum alloy welded member. This invention involves a unique aluminum alloy material that is welded using friction stir welding techniques. The composition of the aluminum alloy includes magnesium (Mg) ranging from 0.3% to 6.0%, copper (Cu) at 0.2% or less, silicon (Si) at 0.1% or less, and iron (Fe) at 0.1% or less, with the remainder being aluminum and inevitable impurities. The second phase particles within the alloy are homogeneously dispersed, with a grain size of 5 micrometers or less, which significantly reduces variations in pit formation during anodizing. This innovation effectively eliminates color tone variations in the anodized coating of aluminum alloy welded components.
