Frequently asked questions

What is T2 Copper (C11000 ETP)?

T2 Copper (C11000 ETP) — Copper. Conductive/thermal base metal — power and heat transfer

What is the maximum service temperature of T2?

Typically about 150 °C; the practical limit depends on media, stress and design life — acceptance per the governing standard.

What is the tensile strength of T2?

The specified minimum tensile strength is 235 MPa for the main product form. Minima for other forms and sizes are listed under "Mechanical minima by form" on this page.

Which standards cover T2?

ASTM B49, ASTM B152/B152M, ASTM B187/B187M, ASTM B283/B283M, EN 12449 (seamless copper tubes), EN 1652 (copper plate, sheet and strip)

Where is T2 typically used?

EV drive & battery busbars (Automotive & Racing); Battery tabs & collectors (Hydrogen & New Energy); Lead frames & packaging (Semiconductor & Vac-Electronics); PV mounting & frames (Solar & Glass)

In which forms is T2 available?

Tube, plate, strip, bar, forgings, wire and other forms — sizes and delivery condition confirmed per order, with EN 10204 3.1 / 3.2 certification.
