Metals

Metals are inorganic materials characterized by a metallic bonding of the atoms, a crystalline structure and a metallic sheen.

They are generally very malleable, ductile, strong and tough. They have high densities and relatively low melting temperatures. Metals are good conductors of electricity and heat, and are easily attacked by corrosion and oxidation. Furthermore they are reflective and feel cool.

Metal alloys contain more than one metallic element. Both metals and metal alloys are described in the metals section.

The above mentioned prices are only meant as guiding figures. Prices vary significantly for different material purity and for different types of raw material (bulk, plate, wire, powder, etc.).

When comparing prices for different materials, it should furthermore be noted that a number of factors influence the amount of material used in a product, e.g. material stiffness, production waste, etc.
