rust proof aluminum jacketing

Nowadays, rust-proof aluminum jacketing is used in many places, but I don’t know what exactly is rust-proof aluminum jacketing? Will the rust proof aluminum jacketing really not be embroidered? Let's take a look at the chemical effect of rust proof aluminum jacketing.


 
A pressure-processable heat-insulating aluminum alloy with good corrosion resistance in air, water, oil and other media. It mainly includes Al-Mn series and Al-Mg series alloys that cannot be strengthened by heat treatment. The rust proof aluminum jacketing alloy with manganese content of 1.0% to 1.7% has high corrosion resistance. The magnesium content in the Al-Mg rust proof aluminum alloy generally does not exceed 7%. As the magnesium content increases, the strength of the alloy increases, σ0 can reach 400MPa, and the plasticity decreases.


 
This type of rust proof aluminum alloy is usually used in an annealed, cold work hardened or semi-cold work hardened state. Low strength, good plasticity, easy pressure processing, good corrosion resistance and welding performance, especially suitable for the manufacture of low-load deep-drawn parts, welded parts and parts that work in corrosive media, such as fuel tanks, pipelines, etc. Another type of rust proof aluminum jacketing alloy is the Al-Zn-Mg-Cu alloy that can be strengthened by heat treatment. It has high tensile strength, excellent seawater corrosion resistance, good fracture toughness, low notch sensitivity and good Molding process performance. Suitable for manufacturing seaplane jacketings and other high-strength sheet metal parts requiring corrosion resistance.
