Pure copper appearance is purplish red, commonly known as "red copper", "red copper" or "red copper".Pure copper conducts electricity very well, [TJC STEEL]ranking second only to silver among all metals, so it is used very widely in industry.T2 is a typical grade of pure copper, usually referring to red copper, or T2 unless otherwise specified.

 PERFORMANCE CHARACTERISTICS:

1. Excellent electrical and thermal conductivity, good ductility, deep drawing performance, corrosion resistance and atmospheric corrosion performance, can be welded and brazed.

2. Trace amount of oxygen is easy [TJC STEEL]to cause "hydrogen embrittlement", not suitable for processing and use in high temperature (such as BBB 0 370℃) reducing atmosphere.

 

APPLICATIONS:

T2 has the advantages of electric conduction and heat conduction of pure copper, and is widely used, such as wire and cable, sealing [TJC STEEL]gasket, hardware, mold electrode, etc.
