Copper Beryllium
C17200, C17300 and C17500 beryllium copper in round bar, plate, sheet, hollow bar and machined form — ASTM B196 / B194 / B534, non-sparking and non-magnetic.
What is copper beryllium?
Copper beryllium is a precipitation-hardening copper alloy containing about 1.8–2.0% beryllium (C17200) or 0.4–0.7% beryllium with cobalt (C17500). After age hardening it reaches 1200–1400 MPa tensile strength and 36–42 HRC — the highest strength of any copper alloy — while staying non-sparking, non-magnetic and highly conductive.
Steelco Metal & Alloys supplies copper beryllium from Mumbai in round bar, plate, sheet, hollow bar and finished non-sparking tools, in solution-annealed (TB00) or age-hardened (TF00 / TH04) temper as required. Every dispatch leaves our Mumbai warehouse with an EN 10204 3.1 mill test certificate (3.2 with TUV, SGS, BV, Lloyd's or IRS witness on request), PMI verification and full heat-number traceability.

Frequently asked questions.
Answers to the questions our Mumbai desk is asked most often.
How strong is copper beryllium C17200?
+
In the fully age-hardened TF00 temper C17200 reaches roughly 1200–1400 MPa tensile strength and 36–42 HRC, comparable to a heat-treated alloy steel, while retaining about 22% IACS electrical conductivity and non-sparking behaviour.
Is copper beryllium safe to machine?
+
Solid copper beryllium is safe to handle. The hazard is inhaling fine dust or fume, so machining, grinding and welding must use local exhaust ventilation and wet methods per the supplier's safety data sheet, which we provide with every consignment.
What is the difference between C17200 and C17500?
+
C17200 is the high-strength grade with about 1.9% beryllium, chosen where hardness and strength matter. C17500 has around 0.5% beryllium with cobalt, giving lower strength but around 45–60% IACS conductivity, which makes it the grade for resistance-welding electrodes and current-carrying components.
