What is better for aluminum housing and stainless steel housing? The excellent properties of aluminum and its alloys are the good appearance, the low weight, the good machinability, the physical and mechanical properties and the good corrosion resistance, so that aluminum and aluminum alloys are many. It is considered economical and practical in the field of application.


The density of aluminum is only 2.7 g / cm 3, which is about 1/3 of the density of steel, copper or brass (7.83 g / cm 3, 8.93 g / cm 3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemicals and many chemical systems.

The surface of aluminum is highly reflective. Radiant energy, visible light, radiant heat and electric waves can be effectively reflected by aluminum, while anodized and dark anodized surfaces can be reflective or absorbent. The polished aluminum is in a wide wavelength range. It has excellent reflectivity and therefore has various decorative applications and applications with reflective functionality.

Aluminum generally exhibits excellent electrical conductivity and thermal conductivity, and certain specific aluminum alloys with high electrical resistance have also been developed, and these alloys can be used in engines such as high torque. Aluminum is often chosen because of its excellent electrical conductivity.

On the basis of the same weight, the electrical conductivity of aluminum is almost twice as high as that of copper. The thermal conductivity of aluminum alloys is about 50-60% of that of copper, which is advantageous for the production of heat exchangers, evaporators, heaters, cookware and cylinder heads and radiators for cars.



Aluminum is non-ferromagnetic, which is an important characteristic for the electrical and electronic industry. Aluminum is not self-igniting, which is important for applications that have to do with handling or contact with flammable and explosive materials. Aluminum is non-toxic and is often used in the manufacture of containers for food and beverages. The natural surface condition has a pleasant appearance. It is soft, shiny and can be colored or textured for aesthetic reasons.

In modern life, aluminum has been widely used in various industries.
