See silver and aluminum mirror reflections
Compared to the paint on the surface of the silver mirror and the paint on the surface of the aluminum mirror, the paint of the silver mirror is obviously deeper; on the contrary, the paint of the aluminum mirror is relatively light. The silver mirror is much clearer than the aluminum mirror, and the geometric reflection angle of the object light source is more standardized. Aluminum mirror low reflectivity, ordinary aluminum mirror reflection performance of about 70%, easily deformed shape and color, and short life, poor corrosion resistance, has been completely eliminated in Europe and the United States. However, aluminum mirrors are easy to produce on a large scale and the cost of raw materials is relatively low.
