Aluminum usually exhibits excellent electrical and thermal conductivity, and some special aluminum alloys with high resistivity have been developed, which can be used in high torque motors. On the basis of the same weight, the conductivity of aluminum is almost twice that of copper. The thermal conductivity of aluminum alloy is about 50-60% of copper, which is conducive to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, automobile cylinder heads and radiators.
Aluminum is non ferromagnetic, which is an important feature of the electrical and electronic industry. Aluminum does not self ignite and can be used in situations involving handling or contacting flammable and explosive materials. Aluminum is non-toxic, so it is more commonly used in food and beverage containers. Aluminum is soft and glossy, and can be colored with texture patterns for a better appearance.
Some aluminum alloys are stronger than structural steel, while pure aluminum and others are extremely low strength. So whether choose aluminum alloy shell or stainless steel shell, need to see what field you use.
