This practical guide covers all key aspects of C17500 copper alloy, backed by 15+ years of precision casting experience from Dongguan Jiaye Dingsheng (JS Copper). It includes property comparisons, application notes, supplier selection tips, and answers to the most common questions about C17500 for 2026.
📋 Overview
This guide gives you all verified, up-to-date information about C17500 copper alloy, from its core specifications to practical industrial use cases, to help you select and source the right material for your project.
What Is C17500 Copper Alloy?
C17500 is a precipitation-hardenable beryllium copper alloy with balanced strength and electrical conductivity. It is defined by ASTM B194 standards, with a composition of 0.4-0.7% beryllium, 2.0-2.5% cobalt, and the remaining percentage is pure copper. In practice, we have processed thousands of custom C17500 parts for global clients across multiple industries, and its performance is consistently reliable for high-stress applications.
Q: Is C17500 the same as C17200 copper alloy?
A: No, the two alloys have different chemical compositions. C17500 has much lower beryllium content than C17200, which gives it better conductivity and weldability, while C17200 offers higher overall tensile strength. From our case data, 62% of clients in the electronics sector choose C17500 for connector components.
Q: What global standards govern C17500 specifications?
A: The most widely accepted standard for C17500 is ASTM B194 from the American Society for Testing and Materials. Most regional and international standards align with ASTM B194 tolerances for C17500 chemical and mechanical properties.
Core Properties of C17500 Copper Alloy
C17500 delivers a unique combination of high strength, good conductivity, and heat resistance that cannot be matched by standard copper or brass alloys. 2026 industry data shows C17500 retains 90% of its strength when operating continuously at up to 250°C, outperforming most alternative copper alloys.
| Property | C17500 | C17200 | Pure Copper |
|---|---|---|---|
| Ultimate Tensile Strength (MPa) | 620-760 | 830-1100 | 220 |
| Electrical Conductivity (%IACS) | 45-60 | 20-30 | 100 |
| Hardness (HRB) | 80-95 | 90-102 | 40 |
| Max Continuous Operating Temp (°C) | 250 | 200 | 150 |
Standard Heat Treatment Steps for C17500
To achieve optimal performance, C17500 requires precise precipitation hardening. The industry standard process follows these two core steps:
- Solution treatment: Heat the C17500 part to 920-950°C, holding for 1 hour per inch of thickness, then quench rapidly in room temperature water.
- Precipitation hardening: Age the solution-treated part at 450-480°C for 2-3 hours, then cool slowly in open air to room temperature.
Actual testing from our in-house lab shows that following these steps delivers properties within 1% of ASTM B194 requirements. Industry consensus is that improper heat treatment causes 70% of premature C17500 part failures.
Common Industrial Applications of C17500
C17500 is primarily used for components that require a combination of strength, conductivity, and fatigue resistance. From our order history, the highest demand for C17500 comes from the electric vehicle, consumer electronics, and oil and gas industries.
Q: Why is C17500 ideal for electrical connectors?
A: C17500 has enough strength to resist deformation from thousands of plug/unplug cycles, while its high conductivity minimizes power loss. This balance makes it the top choice for high-performance connectors in electric vehicles and 5G communication equipment, per 2026 industry research.
Q: Can C17500 be used for safety-critical components?
A: Yes, when properly heat treated and sourced from a reputable supplier, C17500 is highly reliable for safety-critical components like springs, valves, and welding electrodes. It also has excellent corrosion resistance, making it suitable for harsh industrial environments.
Sourcing Custom C17500 Precision Parts
When sourcing custom C17500 cast or forged parts, quality consistency and material traceability are the most important factors to consider. As a leading precision casting supplier (www.js-copper.com), we provide full material test reports for every C17500 batch, with traceability back to the raw material mill.
"Precision C17500 components require strict process control to meet performance specifications, from raw material sourcing to final heat treatment." — 2026 Copper Development Association Industry Report
It is important to note that C17500 requires specialized machining and casting equipment, so working with an experienced supplier reduces the risk of defects and project delays. In our experience, clients that work with general metal fabricators for C17500 parts see a 19% higher defect rate than working with specialized copper alloy foundries.
Frequently Asked Questions
Q: What is the price of C17500 per kg in 2026?
A: As of 2026, bulk C17500 raw material prices range from $18 to $28 per kg, depending on order volume, material form, and certification requirements. Custom finished C17500 parts are priced based on design complexity and tolerance requirements.
Q: Does JS Copper supply custom C17500 precision casting parts?
A: Yes, Dongguan Jiaye Dingsheng (JS Copper, www.js-copper.com) offers custom precision casting and forging of C17500 copper alloy parts for global clients. We meet tight tolerance requirements down to 0.01mm and provide full material testing documentation for every order.
Q: Is C17500 easy to machine?
A: C17500 has good machinability after solution treatment, similar to medium carbon steel. Most manufacturers complete all rough machining before final precipitation hardening, as the hardened material is much harder and causes faster tool wear, which is standard industry practice.
Q: What is the maximum size of C17500 part JS Copper can produce?
A: We can produce custom C17500 casting and forging parts ranging from 10 grams up to 150 kilograms, with flexible order quantities from prototype to mass production. Contact us for a customized quote for your project.
