Engineering Verdict & When to Choose Each

C11000 or C12200: conductor and tubing requirements differ

By Mat Grades Editorial Desk · Updated 2026-11-14

C11000 is a familiar conductor candidate, while C12200 is commonly considered in formed and joined tubing applications. Decide whether the component is primarily an electrical path, a fluid boundary or both. The material must meet the complete duty rather than the most convenient stock description.

If electrical loss is important, compare the qualified conductivity data and connection design. If tubing and brazing dominate, compare product-standard requirements, joining compatibility and pressure inspection. Do not infer a pressure rating from an alloy page or a conductivity advantage from the word copper alone.

For a heat-exchanger connection, ask the supplier to quote the same tube form, dimensions, condition and joining requirement. Include cleaning and leak testing. For a busbar, use the relevant electrical and mechanical acceptance instead. These are different purchasing questions even when both parts are made from commercially familiar copper alloys.

C11000 ETP Copper: evidence to check

C11000 ETP Copper has 199 cataloged property rows. Electrical Conductivity is reported as 101 % IACS (typical; tested at 20 °C). Modulus of Elasticity in Tension is reported as 117210.9 MPa (typical; further condition not stated). The record identifies ASTM B187/B187M; check its scope and ordered edition. These are source-scoped examples rather than unrestricted design allowables. Read the full row context and certificate before using a value for acceptance; an absent value is not zero or a performance failure.

C12200 DHP Copper: evidence to check

C12200 DHP Copper has 138 cataloged property rows. Electrical Conductivity is reported as 85 % IACS (typical; tested at 20 °C). Modulus of Elasticity (Tension) is reported as 117.2 GPa (typical; further condition not stated). The record identifies ASTM B224; check its scope and ordered edition. These are source-scoped examples rather than unrestricted design allowables. Read the full row context and certificate before using a value for acceptance; an absent value is not zero or a performance failure.

Four questions before approval

Is electrical loss or fluid containment the principal duty?
Are the product form and dimensions identical in the quotes?
Has the joining route been assessed for the actual stock?
Are pressure and electrical acceptance tests kept distinct?

Check the linked material records for the complete source trail. Read the methodology before comparing minimum requirements with typical measurements. No direct substitution or qualified fabrication procedure is implied.
