Aluminum powder has a silvery white luster (generally the color of metal in powder form is mostly black) and is often used as coatings, commonly known as silver powder and silver paint, to protect iron products from corrosion and make them beautiful.
H. Low temperature resistance
It is resistant to low temperatures. When the temperature of aluminum is low, its strength increases without being brittle. Therefore, it is an ideal material for low-temperature devices, such as refrigerators, freezers, Antarctic snow vehicles, and hydrogen oxide production devices.
I. Reflectivity
Aluminum plates also reflect light very well, reflecting UV rays better than silver. The purer the aluminum, the better its reflective ability. Therefore, it is often used to make high-quality reflectors, such as solar cooker reflectors.
