Description
C17200 Beryllium Copper Rod TF00 for Mold Inserts & Industrial Components
C17200 Beryllium Copper Rod TF00 Alloy 25, UNS C17200, CuBe2, EN CW103C Beryllium copper rod C17200 is a completely age hardened copper alloy rod made to ASTM B196. This material has a tensile strength of 1110–1320 MPa and a heat conductivity of 105 W/m·K — 3 to 4 times quicker than P20 or H13 steel and is the best option for injection mould bases, core inserts and high-cycle precision components. This grade is supplied ex stock by Dongguan Jiaye Dingsheng Precision Casting & Forging Co., Ltd. created in 1997 with diameters from 10mm to 200mm with delivery in 3-5 days.
What Is C17200 Beryllium Copper Rod TF00?
Temper designation “TF00” indicates that the rod has been precipitation hardened (aged) from the solution-annealed state—formerly designated as the “AT” temper. The regulated ageing procedure results in a microstructural transformation that entraps the high hardness of 36–42 HRC without any further cold work.
The result is a material that combines the mechanical strength of tool steel with the thermal and electrical conductivity of a copper alloy. This combination is not available in normal brass, bronze or most other copper grades.
The chemical composition is strictly regulated; 1.80 - 2.00% Beryllium (Be) and not less than 0.20% Cobalt + Nickel (Co+Ni), the remainder being copper. These limitations are confirmed to ASTM B196 on each manufacturing batch.

Key Performance Advantages
Efficient heat dissipation: quickly takes away internal heat of moulds, minimises moulding cycles and lowers rates of C17200 Beryllium Copper Rod Tf00 warpage and defects.
Stable structural performance: Resistant to long-term clamping force and cyclic injection pressure deformation, hence ensuring dimensional stability in mass manufacturing.
Wear and galling resistance: stable surface hardness results in reduced friction loss of moving parts of moulds, without further surface coating treatments
Good processability: CNC precision machining, mirror polishing, may be used for complicated structure and high precision moulding.
Safety physical property: Non-magnetic, no spark, may meet specific working environment with explosion-proof and anti-interference requirements.
It is often formed into mould core pins and cooling inserts to increase moulding efficiency. It is used to service aerospace bushing and actuator parts to endure high load cyclic operation . It is suitable for HPHT and corrosion resistant work conditions in oil and gas downhole MWD housings. It is also utilised in high current electrical connections and spring contacts for steady long term functioning.

Frequently Asked Questions
Q1: What is the difference between TF00 and TH04?
A1: TF00 is solution-aged with balanced strength and ductility for molds; TH04 is cold-worked and aged with higher strength but lower ductility.
Q2: Is machining of this material safe?
A2: Solid rods are safe for handling. Ventilation and dust removal equipment are required during cutting and grinding.
Q3: How is its conductivity compared to pure copper?
A3: It has 22–25% IACS conductivity and far higher strength, suitable for load-bearing conductive components.
Q4: Can it be used in low-temperature environments?
A4: It maintains stable mechanical performance at cryogenic temperatures and will not become brittle.
Q5: Will TF00 performance change during storage?
A5: Fully aged TF00 material features stable metallurgical properties and no performance attenuation at room temperature.
Q6: What documents can be provided?
A6: EN 10204 3.1 MTC test reports are provided, with ISO 9001, RoHS and REACH supporting documents available.
