C28000 copper coil is made from a copper-zinc alloy containing 60% copper and 40% Zinc. Favored for good corrosion resistance, mechanical properties and formability, it is widely used in construction, marine, industry and other fields.

C22000 copper coil is made from a copper consisting primarily of copper and zinc. This alloy is characterized by excellent electrical conductivity, corrosion resistance, plasticity and forming capabilities, making it a widely used material in construction, decoration and electrical fields.

C21000 copper coil is made from a basic copper-zinc alloy containing approximately 95% copper and 5% zinc. Combining the good electrical and thermal conductivity of copper with the strength of zinc, it is a preferred material for many industrial applications. C21000 copper coil is widely used in various manufacturing fields due to its excellent plasticity, good processability and moderate strength.

C12000 welding performance and cold bending performance is good, generally no "hydrogen disease" tendency, can be processed in the reducing atmosphere, use, but not in the oxidizing atmosphere of processing, use, mainly to pipe applications, can also be plate, belt or bar, line supply. Used as gasoline or gas transmission pipe, drain pipe, condenser pipe, mine pipe, condenser, evaporator, heat exchanger, train parts.

C12000 copper coil is made from a high-purity electrolytic copper, also known as ETP copper (Electrolytic Tough Pitch Copper). Its contains more than 99.9% copper, and small amounts of impurity elements such as oxygen, iron and sulfur.

C10200 copper coil is made from an extremely pure copper material known as oxygen free copper, with a purity of usually over 99.95%. Due to its extremely low oxygen content, C10200 copper coil has excellent electrical and thermal conductivity, as well as good welding and processability.

C10100 copper coil is made from an extremely pure copper alloy with a copper content of more than 99.99%, giving it excellent electrical and thermal conductivity. This high-purity copper is very popular in the electrical and electronic industries where high conductivity and good processability are required.

C11000 copper coil is made from a copper-based alloy with extremely high purity, usually containing over 99.9% copper. This alloy has excellent electrical and thermal conductivity properties other than good corrosion resistance and mechanical strength.
