Copper and its alloys are an indispensable material in industry. Pure copper and copper alloys containing different metal
elements have different characteristics to meet different needs. The users of copper sheet pay great attention to the consi
-stency of tolerance, while the bars pay attention to roundness, concentricity and quick-cutting. The above materials are
widely used in the electronics industry, as well as in the manufacturing of springs, motors, connectors, glasses, probes, etc.
C7701 white copper, also known as zinc white copper, has beautiful color, good ductility, fatigue resistance, corrosion res
-istance, and deep drawing performance. It is used for liquid crystal oscillation element shell, crystal shell, slide plate for
potentiometer, medical machinery, architecture, wind instruments, etc.
