6061 aluminum plate is one of the most versatile of all aluminum alloys, which is also why it's one of the most popular. Plate made from 6061 aluminum plate can be found in a whole range of applications, especially those that have multiple use scenarios where adaptability is a necessity.

The main alloying agents in 6061 aluminum plate are silicon and magnesium. After the rolling process, the plate will typically be strengthened through a process of precipitation hardening, which is what gives this material its superior structural strength and toughness. Precipitation hardening is a heat treatment technique that helps improve the properties of malleable materials such as aluminum.

6061 aluminum plate is able to maintain a good surface finish and features excellent corrosion resistance, even when exposed to atmosphere or seawater. Other benefits include its good machinability and weldability. It should be noted that when 6061 is welded it may lose some of its strength, so further heat treatment might be required.

Typical properties for 6061 aluminum plate include a tensile strength of 45,000 psi, with a yield strength of 40,000 psi. Its Brinell hardness is 95, with an elongation at break of 12% and shear strength of 31,000 psi. The thermal conductivity is 170 W/m-K and strength to weight ratio is 115 kN-m/kg.

Specific uses of 6061 aluminum plate include tooling, architecture, transportation, bridge railing, frames and running boards, platforms, flooring, steps, walkways, cover plates, bicycle frames, SCUBA tanks, fishing reels and small utility boats.
