Sand casting is an extremely flexible process that can benefit from economies of scale when large production runs are needed but is also reasonably flexible to produce complex parts that usually replace several assembled and/or welded components.

Molds produced with silica sand have enough temperature resistance and mechanical strength to cast nearly every metal used in engineering like bronze, brass, aluminium, steels or cast irons.

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.

Sand casting is an extremely flexible process that allows for production runs ranging from a single prototype or replacement casting (one-off) to outputs of thousands of units per month.

Binder and base sand selection are critical to minimize the upfront capital expenditure and price per unit, it’s important that designers and buyers are aware of the options to arrive in an optimum solution.

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:
