6061 aluminum alloy is a cold-worked or extruded forged aluminum product, renowned for its excellent corrosion resistance, high machinability, superior weldability, and good formability. It is one of the most widely used heat-treatable aluminum alloys.
6061 Marine Aluminum is particularly suitable for marine applications such as yachts, speedboats, workboats, and offshore structures. It is easy to stamp, bend, and deep draw. We stock 6061-T6, 6061-T651, and 6061-T6511 to meet diverse application needs.
Aluminum bars from MC Aluminum fully comply with international marine classification standards including CCS, DNV, NK, ABS, BV, LR, KR, and more. Our production and quality management systems adhere to global marine standards, ensuring superior corrosion resistance, excellent weldability, and outstanding impact resistance.
Main Types and Applications of 6061 Aluminum Bars
To meet various structural needs in marine design, 6061 aluminum bars are categorized into:
1. Flat Bars
Flat aluminum used for ship frames, brackets, strips, and guide rails. Their flat profile offers enhanced resistance to bending and shearing stress—ideal for structural reinforcement.
2. Square Bars
Suitable for high-rigidity connectors, mechanical parts, and structural posts. Their square shape allows easy alignment and secure assembly with other components.
3. Round Bars
Commonly used for shafts, pins, bolts, and rivets. The uniform cross-section makes them ideal for applications involving torsional and tensile stress.
