Enamel, in fact, is a kind of composite material in which inorganic glassy materials are solidified on the base metal by melting and firmly combined with the metal. It is mainly composed of metal materials for enamel and porcelain glaze (inorganic glassy materials).

Metal materials of enamel mainly include steel, cast iron, aluminum, copper and stainless steel. Enamel steel (mainly steel plate) generally refers to low-carbon steel plate, that is, steel plate with low carbon content (generally ≤0.08%), which is the main material of positive displacement water heater liner. Because its chemical composition, internal microstructure (metallographic structure), surface condition and mechanical properties play an important role in the quality of enamel, at present, the larger water heater manufacturers in the market all adopt steel plates for enamel produced by Baosteel or WISCO to ensure the enamel quality of the inner container.

Cast iron for enamel refers to iron-carbon alloy with carbon content above 2. 1 1% (iron-carbon alloy with carbon content less than 2. 1 1% is called steel), which is mainly used to produce sanitary wares (bathtubs), chemical instruments, cookers and sewer pipes.

It's actually a craft. Enamel basin, as its name implies, is a basin with enamel texture.
