Aluminium was chosen as the electrical enclosure because it has many very good advantages, light weight, very good heat dissipation performance, good relative strength, corrosion resistance, and low cost. It performs well in harsh environments, can withstand high external impacts, and can shield electromagnetic interference.
Exellent heat dissipation performance
Electricity generally generates a certain amount of heat during the work. If it is placed in a closed box, the heat cannot be discharged in time, and there is a possibility of burnout. The heat dissipation performance of aluminum alloy is very good. The rate is about 121-151 W / (m * k), while other conventional metals, brass 92.1, cast iron 54.4 W / (m * k), tinplate 62.8 W / (m * k), steel 58.6-41.9 W / (m * k). It can be seen that the thermal conductivity is almost twice that of other metals.
Light weight and good relative strength
The density of aluminum is only 2.7g / cm3, the iron alloy is 7.8g / cm3, the copper is 8.960 g / cm3, and the zinc alloy is 6.5g / cm3.
It can be seen that the products of the same size and size are only about 1/3 of other metals, which greatly saves material and transportation costs.
Although his density is small, his strength is not small. Many grades can reach the strength of stainless steel.
Corrosion resistance
Conventional aluminum alloy products usually have good corrosion resistance. Together with special aluminum alloys, such as Mn-Al alloys, they can achieve the effect of stainless steel, which is very difficult to be corroded in seawater.
Generally, aluminum alloy can do a lot of surface treatments, such as plastic spraying, painting, oxidation, electrophoresis, etc., can play a very good surface protection role.
Reigstone Machinery has been developing and manufacturing aluminum electrical enclosures for more than 10 years., with aluminum die casting and aluminum extrusion processes.
