Description
C17510 Beryllium Nickel Copper Bushing — High-Conductivity Bearing Solution for Heavy-Duty Industrial Applications
Jiaye Dingsheng provides C17510 beryllium nickel copper bushings that comply with RWMA Class 3, UNS C17510, and DIN 2.0850. The aged bushing has a tensile strength of 680–880 MPa, an electrical conductivity of 45–60% IACS, and a thermal conductivity of 240 W/m·K. 0.20–0.60% beryllium and 1.40–2.20% nickel make up the composition. OD 10–500mm is available, fully EN 10204 3.1 certified, and CNC machined to ±0.005mm.
What Makes C17510 Different from Standard Bushings?
Under continuous mechanical and thermal pressure, standard brass and phosphor bronze bushings deteriorate. This is resolved by C17510. It maintains constant dimensions under clamping and cycling operation, maintaining 95–100 HRB hardness and 550–720 MPa yield strength at temperatures as high as 400°C. It provides twice as much conductivity for heat dissipation and current-carrying applications as C17200.

Key Performance Advantages
The C17510 beryllium nickel copper bushing accelerates heat dissipation for high-cycle machinery to avoid hot spot damage. Stable high conductivity reduces resistive heat buildup and stabilizes the operation of resistance welding equipment. By avoiding fretting and scuffing with steel shafts, its alloy structure extends service life as compared to conventional bronze components.
With magnetic permeability below 1.001, it causes no sensor interference for precision detection equipment. The material is also non-sparking, adaptable for flammable and hazardous industrial working environments.
Primary Application Areas
Systems for Resistance Welding
utilized in automobile body shops for rotating welding shafts and electrode holders. With 240 W/m·K conductivity and 95–100 HRB hardness, it can withstand repeated high-current pulses and mechanical pressure without experiencing thermal deformation.
Hot Spot Cooling in Plastic Injection Molds
Rapid heat transmission is advantageous for core and cavity cooling bushings in high-cycle molds. Sink marks are decreased and cycle times are shortened by replacing steel inserts.
Downhole Tools for Oil and Gas
Non-magnetic bearings that can withstand high compressive loads underwater and H2S corrosion are necessary for MWD components. All three are met by C17510.
Transformer Terminals and High-Current Power Connectors
This alloy is used in power distribution pivot points and transformer secondary terminals where there is a high current density and limited space.
Ongoing Casting Guides
In steel and aluminum casting lines, guide bushings are subject to abrasion and thermal shock. Premature wear is avoided by maintaining hardness at 300°C.
Quality Control and Inspection
Every bushing undergoes multi-stage inspection per ASTM E18, ASTM E8, and ASTM E114.
Chemical Composition: OES verifies Be and Ni levels against ASTM B534 limits.
Hardness: In old AT conditions, Rockwell B verifies 95–100 HRB.
Conductivity: Eddy current testing verifies that the IACS rating satisfies RWMA Class 3.
Dimensions: verified by CMM to within ±0.005mm.
Non-destructive: DPI verifies surface integrity; ultrasonic testing finds porosity.
A batch-level traceable EN 10204 3.1 Mill Test Certificate is included with every shipment.
Customization and Supply
For CNC-machined components, email designs or order stock sizes. It is possible to configure IDs, ODs, wall thickness, flange geometry, and surface treatment.
Hardness and conductivity targets are adjustable via heat treatment. TB00 and AT tempers available.
In three to five days, stock ships. Personalized quotations in a day. Complete customs paperwork for Southeast Asia, North America, and Europe as well as via air and sea.
Frequently Asked Questions
Q1: How do C17510 and C17200 bushings differ from one another?
A1: The conductivity of C17510 is greater for both current transmission and heat dissipation. For pure high-load mechanical situations, C17200 has greater hardness.
Q2: What is C17510 superior than phosphor bronze?
A2: Longer service life under high-temperature and high-cycle circumstances, as well as increased thermal conductivity and fatigue resistance.
Q3: What is the relevant temper condition?
A3: Formal assembly in the AT/TF00 hardened state. TB00 annealed condition for clients that require more machining.
Q4: Does machining have any safety regulations?
A4: Handling solid items is safe. During processes that produce dust, professional ventilation and protection gear are necessary.
Q5: What sizes are available for customization?
A5: Custom wall thickness and flange constructions, tolerance ±0.005mm, OD 10–500mm, ID 5–450mm.
