MoSER sinks are constructed out of pure type 304 austenitic stainless steel which unlike brass is 100% lead free.   This stainless steel has 18% chromium content, a metal that is oxidation and corrosion resistant.  The sinks also have high nickel content that provides strength and durability.   The austenitic crystalline structure of the stainless steel allow the sinks to retain their shape and structure at all temperatures, from the cryogenic region to the melting point.

Unlike other sink manufacturers that use thinner 20 or 22 gauge stainless steel to make their sinks, all MoSER stainless steel sinks are made with thick 16 or 18 gauge stainless steel and are manufactured with a full undercoating and noise dampening pads to provide exceptional sound deafening.   The thicker gauge steel used by MoSER ensures that the sinks can more easily withstand impacts from everyday objects.
