What are the excellent properties of aluminium and aluminium alloys haomei aluminum seller

Aluminum and aluminum alloys have good electrical and thermal conductivity. Aluminium has good thermal and electrical conductivity, for example, the thermal conductivity of fully annealed high purity aluminium is 2.367 W/(CM-K) at 0~27°C; the resistivity of ultra-pure aluminium (99.990%) is 2.6548 x 10-8 Ω-m at 20°C, which is 64.94% IACS (International Annealed Copper Standard). International Annealed Copper Standard). The combination of aluminium's good electrical conductivity and low density makes it a good conductor of electricity over long distances. For example, aluminium components are found in laptops and many electronic devices, each of which plays an essential role, including heat sinks, which take advantage of aluminium's good thermal conductivity and low density.

Aluminium and aluminium alloys are extremely resistant to corrosion. The surface of aluminium and aluminium alloys has an incomparably thinner film of aluminium oxide than a cicada's wing, which is a natural oxide film formed with oxygen in the air. This film is not only surprisingly thin, but also extremely dense and cannot penetrate oxygen, so it is firmly bonded with aluminium, making it no longer suffer from corrosion, i.e. it will not be oxidised again, so that aluminium and aluminium alloys can be treated and remelted to obtain more than 95% recycled aluminium after their service life has expired.

Aluminium and aluminium alloys combine cleanliness, hygiene, aesthetics and isolation. Aluminium and aluminium alloys are silvery-white metals which, under normal atmospheric conditions, retain their glittering, flawless white colour and are non-toxic and odourless. Although it has been reported that excess aluminium may cause dementia if it accumulates in the hippocampal nerves of the human brain, the World Health Organisation has since stated that there is now insufficient evidence to link dementia in humans to aluminium. Aluminium's cleanliness and hygiene make it an excellent packaging material for food, beverages, pharmaceuticals and alcohol, and it has excellent printability, allowing it to be printed with a variety of patterns, colours and designs.
