C19210 Copper Strip (CuFe0.1P / C1921)
C19210 is an age-hardening, precipitation-strengthened iron-copper alloy strip that delivers excellent electrical & thermal conductivity (≈85% IACS) together with medium strength, outstanding bendability, good corrosion resistance and reliable electroplating performance — the go-to economical high-conductivity strip for lead frames and connector pins.
Key Features & Advantages
-
Very high conductivity ≈85% IACS / 350 W(m·K) — near-copper current-carrying capacity.
-
Excellent bendability (90° & 180° bend) for fine-pitch stamping.
- Good corrosion resistance and stable plating (Sn / Ni / Ag).
- Balanced medium strength for pins, clips and heat-transfer parts.
- Cost-effective alternative to higher-alloy conductive coppers.
Typical Applications
- Semiconductor & IC lead frames
- Connector pins and electrical-industry components
- Air-conditioner heat-exchanger tubing / fins
- Power electronics and terminal blocks

FAQ
Q: What is C19210 used for?
C19210 (CuFe0.1P / C1921) is widely used for IC lead frames, connector pins and air-conditioner heat-exchanger tubing thanks to its high conductivity and bendability.
Q: What conductivity does C19210 have?
≥85% IACS with a thermal conductivity of about 350 W/(m·K).
Q: Is C19210 the same as CuFe0.1P?
Yes. C19210 (ASTM) = TFe0.1 (GB) = C1921 (JIS), a low-iron high-conductivity copper alloy.
