aluminium Magnet wire may have different performance due to different conductors. The conductivity of aluminum conductor is about 61% of copper conductor, but the tensile strength is very small. Since the softer aluminum lacks the elasticity of copper, the handling properties are also different. The MAG-MATE IDC system compensates for these differences by providing stable, long-term aluminum magnet wire termination, which may be because the two IDC slots provide four airtight contact points (two on each beam).

Many manufacturers of small horsepower (FHP) motors sold to the home appliance, heating, ventilation, and air-conditioning equipment industries are seriously evaluating the conversion from copper wire to aluminum wire. The economics of switching to aluminum are very simple: Copper magnet wire currently accounts for 10% of the total cost of a typical FHP motor. At current market prices, the switch from copper wire to aluminum wire may reduce this contribution to less than 2%.

However, in order to obtain equal conductivity, the aluminum wire needs to have a larger cross-sectional area than copper. However, even on the basis of the same conductivity, aluminum is only half the weight of copper. Especially for medium and high-volume FHP motor manufacturers, it is also welcome to reduce material costs and reduce motor weight. From the perspective of price development, it seems that the price increase of aluminum is not as high as that of copper.
