The metal used for enamel is usually steel plate or cast iron. Common enamel products such as enameled cast iron pot, enameled cast iron bathtub, enamel inner tank of electric water heater, industrial enamel reaction kettle and so on. But in addition to the above ferrous metals, there are many non-ferrous metals and alloys that can also be made into enamel products. Today we will introduce copper and copper alloy enamels.

The most suitable copper material for enamel is tin bronze, grades QSn 4.4~2.5, QSn 6.5~0.4, QSn 4~0.3. Special bronzes can also be enamelled, such as aluminum bronze, aluminum iron bronze, aluminum iron manganese bronze and aluminum iron copper bronze. Cupronickel (copper-nickel-zinc alloy) can also be enamel, and its composition range is: 50%~55%Cu, 25%~30%Zn and 18%~22%Ni.

Pure copper is red copper, which is a good enamel substrate. It has good ductility and is suitable for hand-made blanks, but because it is too soft and easily deformed during firing, brass is usually used. The copper content of brass that is more suitable for enamel is 90%~96%, which has both certain ductility and appropriate strength. Brass with copper content less than 60% is not suitable for enamel.
