1) The properties of building and materials are classified into four groups: physical, mechanical, chemical, technological, etc.
2) Resistance to salt aggression and other chemicals (wood)
An important advantage of natural stone is strength, durability, resistance to environmental influences, frost resistance (stone)
Strength; reliability; versatility; combination with other materials (metal)
3) All metals are divided into two groups: ferrous and non-ferrous
4) Ferrous metals and alloys contain iron, non-ferrous metals do not. Ferrous metals are mild steel, carbon steel, stainless steel, cast iron and wrought iron. ... Since they do not contain iron, non-ferrous metals have a higher resistance to corrosion and rust.
