Description
C17510 Beryllium Nickel Copper Round Sleeve – High-Conductivity Bushing Solution for Demanding Industrial Applications
The standard UNS C17510 / CuNi2Be / CW110C alloy, which contains 0.20–0.60% beryllium and 1.40–2.20% nickel, is used in the C17510 Beryllium Nickel Copper Round Sleeve. The completed sleeve has 45–60% IACS conductivity and HRC 30–38 hardness and is made by our facility, which has over 25 years of expertise creating copper alloys. Precision machining with a tolerance of up to ±0.005 mm is supported. Every product is certified ISO 9001, complies with REACH and RoHS regulations, and has a comprehensive MTC certificate for every shipping.
What Is a C17510 Beryllium Nickel Copper Round Sleeve?
The cylindrical bearing bushing C17510 Beryllium Nickel Copper Round Sleeve is composed of low-beryllium copper alloy with nickel added. It addresses the problems of thermal softening and fatigue failure of common bronze and copper sleeves under cyclic loads by balancing mechanical strength, electrical conductivity, and thermal conductivity. It is a feasible substitute for C17500 in production settings with stringent standards since it is a cobalt-free alloy that satisfies international industry compliance regulations.
Material Composition & Temper Conditions
Batch composition is strictly controlled: Beryllium 0.20–0.60%, Nickel 1.40–2.20%, copper balance (total effective elements ≥99.5%). Two temper options are available for different assembly processes:
| Element | Content |
|---|---|
| Beryllium (Be) | 0.20 – 0.60% |
| Nickel (Ni) | 1.40 – 2.20% |
| Copper (Cu) | Balance |
| Cu + Named Elements | ≥ 99.5% |
Two supply temper conditions are available depending on your assembly process:
-
TB00 Annealed: Soft state for press-fit assembly, with on-site aging treatment to achieve standard hardness
-
TF00/TH04 Pre-Aged: Finished hardness and wear resistance, no secondary heat treatment required
Choosing the right temper saves time and avoids dimensional distortion during manufacturing.
Mechanical & Physical Properties
All values below reflect the age-hardened condition (TF00/TH04).
| Property | Value |
|---|---|
| Tensile Strength | 700 – 1000 MPa |
| Hardness | HRC 30–38 (HB 280–350) |
| Electrical Conductivity | 45 – 60% IACS |
| Thermal Conductivity | ~180 W/m·K |
| Max. Operating Temperature | Up to 480°C |
| Magnetic Properties | Non-magnetic |
| Spark Properties | Non-sparking |
| RWMA Classification | Class 3 Equivalent |
The 45–60% IACS conductivity is the key differentiator from C17200 (Class 4). It minimizes resistive heating in current-carrying applications, which directly reduces energy loss and component wear.
Dimensional Tolerances & Precision
You can specify custom inner diameter (ID), outer diameter (OD), and wall thickness based on your design requirements.
| Dimension | Tolerance |
|---|---|
| ID / OD Tolerance | Up to ±0.005mm (precision honed) |
| Concentricity | ≤ 0.01mm |
| Surface Finish | Ra 0.4 – 0.8 µm (precision ground) |
| Optional Surface Treatment | Silver or nickel plating available |
These tight tolerances make this sleeve suitable for direct installation in high-precision assemblies without additional machining on your end.
Key Performance Advantages
High conductivity reduces thermal fatigue and prolongs the life of welding accessories by speeding up heat dissipation.
Under cyclic heat and load circumstances, thermal deformation is prevented by stable hardness at 480°C.
Long-term rotational and reciprocating operation is prevented by the anti-galling characteristic.
For international industrial procurement, a cobalt-free recipe satisfies standard environmental regulations.
Typical Application Scenarios
It is frequently used to lower the frequency of maintenance for electrode sleeves in welding equipment. used in injection mold cooling cores to increase product stability and save molding cycles. bushings for oilfield and aircraft instruments that can withstand corrosion and vibration. Additionally, it provides wear resistance and steady current transmission for rotating electrical contact components.
Quality Control Process
We apply three-stage inspection: OES composition verification for raw materials, real-time parameter monitoring throughout manufacturing, and final dimensions, hardness, conductivity and internal defect testing. total MTC reports are included with every shipment in order to achieve total batch traceability.
