Material Data to Review Before Quoting
This table gives your engineering, purchasing, or quality team a fast way to compare the source callout with the U.S. material starting point. It supports RFQ review; it does not replace the approved drawing or material specification.
| Item to compare | CW101C | C17200 |
|---|---|---|
| Beryllium (Be) | 1.80-2.10% | 1.80-2.00% |
| Cobalt + Nickel (Co + Ni) | 0.20-0.60% | 0.20% min. |
| Cobalt + Nickel + Iron (Co + Ni + Fe) | 0.60% max. | 0.60% max. |
| Copper (Cu) | Balance | Remainder; Cu + named elements 99.5% min. |
| Practical conclusion | Very close CuBe2 chemistry | Commonly treated as the U.S. / UNS cross-reference for CW101C |
Composition ranges checked against Copper Development Association C17200 data and public CW101C / CuBe2 reference data from Metonorm and eMetal.
Where This Cross-Reference Helps
This page is useful for high-strength copper alloy parts, springs, wear components, tooling inserts, and conductive machined parts.
If your print uses CW101C, include the full drawing, tolerances, quantity, required supply form, and inspection notes with the RFQ. That lets us quote the material and manufacturing route with fewer back-and-forth questions.
Related Specifications You May See
The same material family may also appear under these names or standards: CuBe2, CW101C, QBe2, C1720, CuBe2.
If one of these appears on your drawing or purchase record, include it with the RFQ. It helps us understand the original specification and avoid quoting a material that only looks similar on paper.
Before You Substitute the Material
Temper, heat treatment, hardness, and conductivity are critical for beryllium copper. Confirm those details before quoting or substitution.
Cross-reference charts are helpful for purchasing and maintenance teams, but they do not replace a formal material specification, mill certificate, or customer-approved drawing.
