Product Overview
Placa de aluminiu 6061 is an aluminum-magnesium-silicon (Al-Mg-Si) alloy from the 6000 series, one of the most versatile and widely used heat-treatable aluminum alloys. It can be strengthened through heat treatment to achieve excellent mechanical properties, combining medium-to-high strength with good formability, weldability, machinability, and corrosion resistance. Our 6061 aluminum plates are available in T4, T6, T651 and O tempers, in flat and diamond tread patterns, with custom sizes and surface finishes. It is the preferred choice for structural, mechanical, and architectural applications worldwide.
