ã€China Aluminum Network】 When the hub temperature is high, it must not be cleaned directly with cold water. Allow it to cool naturally before cleaning, otherwise it will damage the aluminum alloy hub, and even make the brake disc deformation and affect the braking effect. In addition, cleaning the aluminum Taiwan gold hub with a cleaning agent at a high temperature will cause a chemical reaction on the surface of the hub, which will lose its luster and affect the appearance.
If driving a car every day, wash the rim at least once a week. When cleaning, you can use a cleaning agent with a sponge or a brush and then rinse with plenty of water. But do not use too hard brushes, especially iron brushes, as this will damage the hub surface. In addition, there is a layer of metal protective film on the hub itself, so be careful not to use paint brighteners or other abrasive materials when cleaning.
In addition, in vehicles that are traveling in areas that are relatively humid in the south or in coastal cities, wheel hubs should be cleaned to prevent corrosion of aluminum surfaces by rain or salt.
Commonly, Hard ferrite is a type of ceramic Fe2O3,BaCO3 or SrCo3 compund material.The density of ferrite magnets about 5g/cm3, and they are divided to hard ferrite and soft ferrite.
They are both electrically nonconductive and ferrimagnetic.Of course,they also can as Construction Magnet. Hard ferrites have higher coercivity and higher remanence after magnetization. Ceramic magnets are cheap and widely used in household appliance such as refrigerator horseshoeshaped magnet, letric motors, teleconmmunication loud speaker,magnetic recording.etc.
Soft Ferrite Magnet is a sort of Fe2O4,Zinc or Nickel compund material.They have a low coercivity thus called soft ferrites. Because of their comparatively low losses at high frequencies.
They are extensively used in the cores of RF tranformers and inductor in applications of AM redios.
