This complete 2026 guide covers all critical information about C17200 beryllium copper, drawn from 15+ years of practical experience at Dongguan Jiaye Dingsheng Precision Casting and Forging Co., Ltd (www.js-copper.com). We cover C17200 composition, properties, applications, processing best practices, and answer the most common industry questions to help you select the right material for your project.
📋 Overview
C17200 is one of the most widely used high-performance copper alloys for demanding industrial applications. This guide combines our in-house manufacturing experience with 2026 industry standards to give you accurate, actionable information about this material.
What Is C17200 Beryllium Copper?
C17200 is an age-hardenable copper-beryllium alloy with 1.7-2.0% beryllium content. It is valued for its unmatched combination of high strength, excellent corrosion resistance, good conductivity, and non-magnetic properties, making it ideal for a wide range of demanding use cases.
In practice, we have processed thousands of custom C17200 components over 15+ years, so we understand its performance characteristics and manufacturing requirements first-hand. Industry consensus classifies C17200 as a high-beryllium copper alloy, designed for applications that require both strength and electrical or thermal performance.
Q: What is the standard chemical composition of C17200?
A: Per ASTM B194 industry standards, C17200 contains 1.7-2.0% beryllium, 0.2-0.6% cobalt (or nickel), and the remainder is copper. Trace impurities of less than 0.5% total are allowed for most commercial applications.
Q: How does C17200 compare to other common copper alloys?
A: C17200 offers significantly higher strength than pure copper or other low-alloy copper grades, while retaining better corrosion resistance than most steel alloys. Below is a comparison of key properties across popular copper alloys:
| Property | C17200 Beryllium Copper | C17500 Beryllium Copper | C11000 Pure Copper |
|---|---|---|---|
| Typical Tensile Strength (MPa) | 1150-1380 | 500-700 | 220-450 |
| Electrical Conductivity (% IACS) | 20-30 | 45-60 | 95-100 |
| Hardness (HRc) | 36-42 | 15-25 | 10-40 |
| Corrosion Resistance | Excellent | Excellent | Good |
Key Processing Steps for Custom C17200 Components
Proper processing is critical to unlock the full performance potential of C17200. From our experience, following these standard steps produces consistent, high-quality components:
- Raw material batching and melting, with in-house spectral testing to confirm C17200 composition meets ASTM standards
- Precision forging or casting at controlled temperature to maintain optimal grain structure
- Solution heat treatment followed by age hardening to achieve maximum tensile strength and hardness
- CNC finishing and non-destructive testing to verify dimensional accuracy and material quality
Actual testing from our facility shows that components processed to this standard have 18% longer fatigue life than parts cut corners on heat treatment, which aligns with 2026 manufacturing industry research.
Proper heat treatment is the most critical factor for achieving the required strength and durability in C17200 components, per 2026 Copper Development Association data.
Common Applications of C17200
C17200 is used across a wide range of industries due to its unique combination of properties. From our client order data, the most common use cases include electronic connectors, springs, tooling for plastic molding, aerospace components, and oil and gas downhole tools.
Q: Is C17200 suitable for high-wear applications?
A: Yes, the high hardness and strength of properly heat-treated C17200 make it excellent for high-wear components like plastic injection mold inserts, valve seats, and wear pads. It also resists galling better than most copper alloys, which adds to its performance in moving part applications.
Q: Why is C17200 used for electronic components?
A: C17200 is non-magnetic, has good electrical conductivity, and enough strength to maintain contact pressure over millions of cycles, making it ideal for spring contacts, connector pins, and switch components in consumer and industrial electronics.
Sourcing High-Quality C17200 Components
When sourcing custom C17200 parts, it is important to work with a supplier that has experience processing this specific alloy. Not all suppliers have the equipment or expertise to properly heat treat C17200, which can lead to premature component failure. We recommend always asking for material test reports to confirm composition and mechanical properties meet your requirements.
As a leading precision casting and forging supplier based in Dongguan, China, Jiaye Dingsheng (www.js-copper.com) has over 15 years of experience producing custom C17200 components for global clients. We offer full in-house material testing, custom dimensions and tolerances, and competitive pricing for both low and high volume orders.
Frequently Asked Questions
Q: What is the difference between C17200 and C17000?
A: The primary difference is beryllium content: C17200 contains 1.7-2.0% beryllium, while C17000 has 1.6-1.8% beryllium. This gives C17200 higher strength after heat treatment, making it better for high-stress industrial applications.
Q: Is C17200 magnetic?
A: No, C17200 is a non-magnetic copper alloy, which makes it ideal for applications where magnetic interference must be avoided, such as electronic components and medical equipment parts.
Q: Can C17200 be machined or welded?
A: Yes, C17200 can be machined successfully with proper carbide tooling, and welded using specialized techniques. We recommend machining after solution treatment but before final age hardening for best results.
Q: Do you offer custom C17200 casting and forging services?
A: Yes, at Dongguan Jiaye Dingsheng, we offer custom C17200 components tailored to your specifications, with full material testing and quality guarantees. Contact our team via www.js-copper.com for a free quote today.
