3003 aluminum plate is a common product of aluminum-manganese alloy series. Better than having manganese alloy elements, this product has excellent anti-rust properties, also known as anti-rust aluminum plate. The strength is about 10% สูงกว่าของ 1100, and the formability, weldability and corrosion resistance are all good.
It is used for processing parts and components that require good formability, high corrosion resistance and good weldability, or work that requires both these properties and higher strength than 1XXX series alloys, such as kitchenware, food and chemical products handling and Storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed with thin plates, general utensils, heat sinks, cosmetic plates, photocopier rollers, and ship materials.
The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; there is still a small amount of conductive material. copper to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial aging hardening function.
The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, ทนต่อการกัดกร่อนได้ดี, weldability, and good oxidation effect.
