Balford processes copper into stamped base plates, washers and formed components for electrical and thermal applications, with controlled burr and surface condition.
Stamped copper base plates for power modules in HVAC and industrial drives.
Stamped and formed copper components for electrical and thermal assemblies.
Copper is processed at Balford for electrical and thermal components — stamped base plates for IGBT power modules, formed parts and precision washers — with controlled conductivity-critical dimensions.
What each grade actually is, what the standard guarantees, where it is used, and which grade to move to when the first choice does not work. Values are the standard minimums or typical annealed ranges; every lot is confirmed against its mill certificate.
Conductivity is the whole point; oxygen content decides whether the part can be brazed or welded without hydrogen embrittlement.
| Grade | EN | UNS / AISI | JIS | GB | Chemistry (wt%) | Mechanical | Typical use | Use instead when… |
|---|---|---|---|---|---|---|---|---|
| C1100 / T2 | — | C11000 | C1100 | T2 | Cu ≥99.90 · O ≈0.02–0.04 | Annealed: Rm ≈200–250 · A ≥30 | Busbars, terminals, gaskets, shielding | The standard ETP copper for conductivity and cost |
| C1020 / TU1 | — | C10200 | C1020 | TU1 | Cu ≥99.95 · O ≤0.001 | Annealed: Rm ≈200–250 · A ≥30 | Vacuum, brazed and hydrogen-fired assemblies | Replaces C1100 where oxygen-free copper is required |
Rm = tensile strength, Rp0.2 = 0.2% proof stress, A80 = elongation at 80 mm gauge. Chemistry is the ladle range from the named standard. Cold work, temper and heat treatment move the mechanical values, so the certificate for the delivered coil is the governing document.

Real projects from Balford's production history:
Balford deep draws and stamps copper on presses from 25 t to 350 t, up to Ø250 mm, under ISO 9001:2015.
Stamped copper base plates for IGBT power modules, formed electrical parts and precision washers. Contact us with a drawing for a DFM review.
Copper is soft and prone to burring; die clearance and tooling are tuned for clean edges, with deburring where required.
Yes — surface treatment can be coordinated, or parts supplied ready for plating.
Send us your 2D drawing or STEP/IGES model. We will review material, tolerances, forming requirements and production volume before quoting.
