Extruded aluminum alloy motor housing

The main feature of the extruded aluminum alloy motor housing is good heat dissipation. The internal temperature of the motor is cooled to between 50-60 ℃ by water circulation, which is beneficial to the heat dissipation of the automobile motor. The motor has low vibration, low noise, and has the characteristics of waterproof, dustproof and anti-corrosion. Aluminum has relatively light metal properties and is lighter than the products made, which can reduce the weight of the entire vehicle and facilitate transportation and installation.


 
Advantages of extruded aluminum alloy motor housing
 
Light weight, the density of aluminum is approximately equal to 2.7g/cm3
Corrosion resistance, aluminum alloy will not be corroded when exposed to the air, and the corrosion resistance is far better than steel. The main reason is that aluminum has a greater affinity with oxygen. An oxide film will adhere to the surface of the aluminum alloy. This film has strong adhesion and density, with a thickness of 0.01-0.05μm. This film makes the aluminum alloy excellent in corrosion resistance. The aluminum motor housing will also undergo anodization, which improves the hardness, corrosion resistance and wear resistance of the aluminum alloy surface.
High strength, after the aluminum alloy is strengthened by heat treatment, it can be comparable to high-quality alloy steel.
Easy to shape, aluminum alloy can be machined by turning, milling, CNC etc.
It is easy to dissipate heat. The thermal conductivity of aluminum alloy is inferior to copper, but its conductivity is high. Aluminum is a better metal medium for heating and cooling.
Non-magnetic, aluminum alloy is non-magnetic and does not produce sparks when impacted, so it is an ideal material for the motor housing.
Recyclable, aluminum has a low melting point and is easy to melt and regenerate.
