Copper alloys are widely used in engineering and aesthetic applications.

In technical applications, these alloys are usually specified for their unmatched corrosion resistance, electric conductivity and low friction with other metals.

For decorative and related applications, it is sought after mainly for its ability to produce a polished reddish or golden finish which stands the test of time and the elements.

Stainless steel is a metal that has a lot of applications when it comes to manufacturing various parts for different types of machines and equipment. Stainless steel has strength, durability, wear resistance, and especially outstanding corrosion resistance in a wide range of environments. Stainless Steel is a large family of alloys that contain a variety of elements, primarily iron with chromium and nickel, but may also contain molybdenum, manganese, silicon, vanadium and numerous others. This variety of compositions allows customers to choose an alloy meeting the particular needs of their product.

The term stainless steel (SS) is used to encompass a wide array of materials with varied physical, chemical, and mechanical properties.

For the design engineer, it is essential to identify the different alloys available, their properties and the equivalent casting grades that correspond to the well-known wrought formulations.

In more detail, stainless steel may be categorized according to its microstructure:
