Description
C17200 Beryllium Copper Hex Bar – High-Strength Alloy 25 for Precision Machining & Industrial Safety Applications
C17200 Beryllium Copper Hex Bar (Alloy 25) is a wrought copper-based alloy with 1.8–2.0% beryllium and trace cobalt and nickel elements. With over 25 years of production experience since 1997, Dongguan Jiaye Dingsheng produces this hexagonal bar complying with ASTM B196/B196M standards. After TF00 temper treatment, the material reaches up to 1450 MPa tensile strength and 45 HRC hardness. Standard sizes are in stock for 3–5 day delivery, and every batch is supplied with complete EN 10204 3.1 MTC test reports.
What Is C17200 Beryllium Copper Hex Bar?
C17200 Beryllium Copper Hex Bar features a prefabricated hexagonal structure, matching automated Swiss lathe machining requirements. It omits flat surface milling procedures in fastener production, cutting material waste and processing cycle time. This alloy balances copper conductivity and steel-level mechanical strength, with 17–25% IACS conductivity. It fits non-sparking safety tools, downhole magnetic-insensitive equipment and long-cycle fatigue-resistant structural parts.
Chemical Composition
| Element | Content |
|---|---|
| Beryllium (Be) | 1.80 – 2.00% |
| Cobalt + Nickel (Co + Ni) | 0.20 – 0.60% |
| Copper (Cu) | Balance |
Chemical composition is verified during incoming raw material inspection using Optical Emission Spectroscopy (OES), and re-confirmed at final inspection before shipment.

Temper Options: TD04 vs. TF00
Different tempers adapt to diverse production processes. TD04 cold-drawn temper delivers stable strength for secondary forming processing. TF00 solution aging temper achieves maximum strength and cross-section dimensional stability, suitable for most precision structural parts and safety-related components. Our technical team can recommend suitable temper status according to end-use scenarios.
Core Performance Advantages
-
Balanced strength and conductivity: Matches mechanical properties of many engineering steels while retaining basic conductive and heat-dissipating performance of copper alloys.
-
Non-sparking & non-magnetic: Avoids ignition risks in flammable environments and magnetic interference for downhole detection equipment.
-
Fatigue and corrosion resistance: Resists cyclic load wear, hydrogen embrittlement and stress corrosion, adapting to marine and chemical industrial environments.
Application Areas
This material is widely used in oil and gas downhole detection components to adapt to high-pressure working conditions. It applies to aerospace vibration-resistant bushings and fasteners relying on anti-galling performance. It is also processed into non-sparking safety tools and hex bolts for chemical plants and explosion-proof working areas.
Quality Control & Inspection Protocol
All products pass five major inspections before delivery, including OES composition analysis, ultrasonic internal flaw detection, mechanical tensile and hardness testing, precision dimensional calibration and eddy current conductivity verification. Full batch traceability is implemented, with complete test documents provided for each order.
Safety Handling Note
Solid bars cause no safety risks during daily storage and handling. Dust extraction and ventilation equipment must be equipped during cutting and grinding to comply with industrial safety specifications.
Frequently Asked Questions
