Why engineers alloy metals
Alloying changes phase balance, microstructure and properties so a base metal can meet specific strength, corrosion, wear, temperature or manufacturing requirements.
How alloys are classified
Carbon steels, alloy steels, stainless steels and cast irons.
Aluminium, copper, nickel, titanium, magnesium, zinc and other alloy systems.
Strength or microstructure can be modified through controlled heating and cooling.
Plastic deformation raises strength while generally reducing ductility.
Composition is only the start
Mechanical properties depend on phases, grain size, precipitates, inclusions, defects and residual stresses. Casting, forging, rolling, welding, additive manufacturing and heat treatment can produce different behavior from nominally similar chemistry.
Explore existing metal and alloy guides
Use the Copper Alloys Library for brass, bronze and copper-nickel selection; the Aluminum Alloys Library for wrought and cast grades; and the Steel Library for carbon, alloy and stainless steels. The Material Comparisons page provides an initial side-by-side overview. Always verify property values against the relevant product standard and material certificate.
