Pneumatic diaphragm pump aluminum alloy material
The general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, and lithium.
Aluminum alloy has low density but relatively high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is second only to steel. .
Aluminum alloys are divided into two categories: cast aluminum alloys, which are used in the as-cast state; deformed aluminum alloys, which can withstand pressure processing and have higher mechanical properties than the as-cast state. It can be processed into various shapes and specifications of aluminum alloy. Mainly used in the manufacture of aviation equipment, daily necessities, construction, pumps, etc.
According to the processing method, aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy. Wrought aluminum alloy is divided into non-heat-treatable reinforced aluminum alloy and heat-treatable reinforced aluminum alloy. The non-heat-treatable strengthened type cannot be improved by heat treatment, but can only be strengthened by cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and anti-rust aluminum. Heat-treatable reinforced aluminum alloys can improve mechanical properties through heat treatment such as quenching and aging. It can be divided into duralumin, forged aluminum, super-duralumin and special aluminum alloys.
Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.
Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum-rare earth alloys according to their chemical composition. Among them, aluminum-silicon alloys also have simple aluminum-silicon alloys (not heat-treated for strengthening, lower mechanical properties, casting Good performance), special aluminum-silicon alloy (heat treatment can be strengthened, high mechanical properties, good casting performance)
The material of the 2008 Beijing Olympic torch "Auspicious Clouds" is aluminum alloy.
