Description
C17200 Beryllium Copper Tooling Plate for Hot Runner Systems — High Thermal Conductivity & Pressure-Resistant Solution
C17200 Beryllium Copper Tooling Plate (UNS C17200 / CuBe2 / Alloy 25) is the material of choice for high hot operating applications. This plate is made by Dongguan Jiaye Dingsheng Precision Casting & Forging Co., Ltd. with more than 25 years experience of copper alloy production, tensile strength 1110-1320 MPa, thermal conductivity 105-125 W/m·K, hardness 36-42 HRC. EN 10204 3.1 Mill Test Certificates ASTM B194 ISO 9001 RoHS and REACH Specially designed for injection manifolds, valve gate plates and nozzle housings used in the mould making, aerospace and precision electronics sectors.
What Is C17200 Beryllium Copper Tooling Plate?
This copper-beryllium alloy is sometimes referred to as Alloy 25 or EN CW103C. It contains 1.80-2.00% Beryllium, a minimum of 0.20% Co+Ni and the rest is copper. It is supplied in the solution heat-treated and age-hardened condition (TF00/AT) for best dimensional stability.
It possesses a thermal conductivity of 3 to 4 times higher than standard tool steels, up to 130 W/m·K, and hardness values up to HRC 45. The combination is effective when steel does not provide enough heat dissipation.
You have a material that’s non-magnetic, non-sparking and resistant to galling. Those features open the door to applications steel can’t properly cover.

Core Performance Advantages
Enhanced thermal uniformity
C17200 Beryllium Copper Tooling Plate in multi-cavity mould designs offers thermal conductivity exceeding 105 W/m·K to remove hot and cold areas. It regulates resin viscosity during injection, reducing part warpage and scrap rates.
High Pressure Structural Integrity
The manifold plate has a yield strength of 950-1150 MPa and is resistant to bending and leaking even at excessive plastic injection pressures. The sealing tolerances surrounding the valve gates and melt channels are not affected by long manufacturing runs.
Resistance to thermal fatigue
Normal materials would warp with the constant heating and cooling cycles but they are dealt with without distortion. This is especially true for temperature sensitive technical polymers like POM, PA and PEEK.
Creep resistance at high temperatures
Tight tolerances are maintained at operation temperatures up to 250°C (continuous). This preserves the integrity of the nozzle housing and valve gate fittings throughout the life of the tool.
Quality Control Process
Before shipping all plates are inspected by a three-stage process:
- Incoming Inspection: Beryllium content certified by Optical Emission Spectroscopy (OES) to be within the 1.80-2.00% standard.
- In-Process Control: Rockwell C (HRC) hardness mapping throughout the plate surface indicates homogeneous age-hardening. Ultrasonic examination in accordance with ASTM A388 reveals internal voids or impurities.
- Final Inspection: Heat treatment success is confirmed by electrical conductivity (IACS%). CMM based dimensional verification checks flat-ground tolerances and lowers the machining overhead for the end user.
All batches of material are completely traceable from source material to completed product distribution.
Application Scenarios
Injection Moulding Plastic
Use C17200 Beryllium Copper Tooling Plate as hot runner manifold plates, mould inserts, cores and cavity inserts. Its high thermal conductivity cuts cycle durations by up to 50%, quickly removing heat from areas unreachable by cooling lines.
Resistance Welding and Electronics
For structural tooling in high frequency connections and welding electrodes. The material has mechanical stability under localised heat stress for long term repeatability in precision electronic assembly.
Oil & Gas Downhole Equipment
Its non-sparking properties and resistance to hydrogen embrittlement make it ideal for use in components of drill string and downhole equipment in sour gas conditions.
Aerospace & Automotive
Used in precision tools and fixtures where high strength to weight ratio, thermal stability and dimensional accuracy must be maintained under cyclic loading circumstances.

Frequently Asked Questions
Q1: What are the possible thicknesses and lead times?
A1: We carry standard plates for rapid delivery. Custom precision ground thicknesses typically take 2–4 weeks depending on drawing requirements and ASTM certification level needed.
Q2: Is this plate machinable?
A2: Yes — provided that wet machining or sufficient ventilation is provided. When cutting or grinding, fine beryllium-containing dust may be inhaled and should be avoided by following OSHA requirements.
Q3: How does it behave in corrosive environments?
A3: Good resistance to saline water and various organic acids. Suitable for maritime tools and chemical processing equipment.
Q4: Is C17200 Beryllium Copper Tooling Plate weldable?
A4: Yes, TIG or MIG. After welding, a post-weld heat treatment is often necessary to restore complete mechanical characteristics.
