6061 Aluminum Rod for Boat Building
6061 aluminum alloy is an alloy widely used in industrial manufacturing and engineering fields, especially in aerospace, automobile manufacturing, mechanical structure, electronic equipment and architectural decoration. According to the different heat treatment and cold working processes, 6061 aluminum can usually be divided into five tempers(T4, T5, T6, T651 and O). Each state corresponds to different mechanical properties and application characteristics. Choosing the most suitable aluminum alloy temper is crucial to fully realize the potential of the material.
6061-T4 aluminum rod
T4 temper is the natural aging stage after solution treatment. At this time, the aluminum bar has good formability and weldability, but the hardness and strength are relatively low. 6061 aluminum bars in this state are suitable for the manufacture of parts with high plasticity requirements, such as mold making, parts that need to be bent or stretched, etc.
6061 T5 aluminum bar
T5 temper is to achieve aging hardening through artificial rapid cooling after solution treatment. It has higher hardness and tensile strength than T4 state, but still maintains good formability. It is suitable for occasions with certain strength requirements and certain processability, such as rail transit components, bicycle frames, etc.
6061 T6 aluminum
The T6 temper is a state of artificial aging after solution treatment, which makes the aluminum bar reach the highest strength level, and its hardness, strength and fatigue performance are excellent. It is often used to manufacture parts that require high strength and high corrosion resistance, such as aircraft structural parts, precision mechanical parts, high-pressure vessels and some structural components of heavy vehicles.
6061 T651 aluminum tube
The T651 temper is pre-stretched on the basis of the T6 state, which further improves the stress distribution of the material, reduces internal stress, improves dimensional stability, and maintains high strength characteristics. It is particularly suitable for occasions that require precision processing and stable dimensions, such as aerospace fasteners, precision instrument components, thin-walled pipes and plates, etc.
6061 O aluminum
The O temper is the annealed state, which is characterized by softness, good plasticity, but low strength. 6061-O aluminum tube is suitable for occasions with high requirements for material forming and ductility, such as decorative sheet and food packaging.
When choosing the state of 6061 aluminum bar, you should consider the final use of the product, the type of load it needs to bear, the processing method, and the use environment. At the same time, the correct heat treatment process is also a key link to ensure the performance of the material. Another alloy of aluminium boat extrusions that is commonly used is aluminum 6082.
