Is the belt alloy aluminum plate or steel plate better?

Both of them are superior to strip alloy aluminum plate in weight, heat dissipation and shape.

Alloy aluminum plate has the advantages of light weight, good corrosion resistance, good thermal conductivity and good ductility. Lighter than steel plate, more comfortable to wear; At the same time, the alloy aluminum plate has good corrosion resistance and is not easy to rust; Good thermal conductivity and rapid heat dissipation; Good ductility, and can make ornaments of various shapes. However, the heat dissipation of steel plates is not particularly good, and the weight is also large. Harder, single shape.
