Product information

Brand: TU3
TU3 oxygen-free copper has excellent electrical and thermal conductivity, high purity, no "hydrogen disease" or very little "hydrogen disease", good processing performance and welding, corrosion resistance, cold resistance. ‌ These characteristics make TU3 oxygen-free copper suitable for the production of electric vacuum instrumentation devices, widely used in CNC lathes, stamping, CNC, optics, aviation, mechanical equipment, mold manufacturing, electronics, precision instruments, transportation, textile, mechanical and electrical, metallurgy, military industry, ships, chemical industry, hardware manufacturing, mobile phone industry, medical industry and other fields. In addition, the typical uses of TU3 oxygen-free copper also include CPU cooling parts, vacuum seals, transistor components, glass metal seals, printed circuit boards, wire and cable shielding tape, connector materials ‌.

Product parameter

Chemical composition
The content of copper is required to be ≥99.95%, while the content of oxygen is strictly controlled to ≤0.0010%. This strict composition control makes TU3 oxygen-free copper widely used in electric vacuum devices, instruments, meters and other fields. In addition, the content of other impurity elements in TU3 oxygen-free copper is also clearly defined, such as tin (Sn) ≤0.002%, zinc (Zn) ≤0.003%, lead (Pb) ≤0.004%, phosphorus (P) ≤0.002%, nickel (Ni) ≤0.002%, iron (Fe) ≤0.004%, antimony (Sb) ≤0.002%, and zinc (Zn) ≤0.002%. Sulfur (S) ≤0.004%, arsenic (As) ≤0.002%, bismuth (Bi) ≤0.001%. 
Mechanical property
High hardness ‌ and ‌ high conductivity ‌ : TU3 Oxygen-free copper has excellent electrical and thermal conductivity, ensuring its excellent performance in electrical and electronic applications. Specifically, its electrical conductivity reaches 98% IACS (International Annealed copper standard), electrical conductivity is 57 MS/m, thermal conductivity is 385 W/(m·K), these indicators show its excellent electrical and thermal conductivity ‌.
‌ high softenability ‌ : TU3 oxygen-free copper has high softenability, which means that it can quickly soften when subjected to pressure or heat, adapt to complex processing and treatment processes, while maintaining its physical and electrical properties ‌.
‌ excellent cold working properties ‌ : TU3 oxygen-free copper has good cold working properties, and can maintain the stability and consistency of the material in the cold working process, which is especially important for precision machining and the manufacture of complex parts ‌.
‌ medium strength ‌ : In addition to high conductivity and high softening, TU3 oxygen-free copper also has medium strength, which can ensure the electrical performance at the same time, but also has a certain structural support capacity ‌.
