📋 Overview
This industry-focused reference aggregates first-hand production and application data of C17200 beryllium copper updated to 2026, helping users avoid common material selection mistakes and lower comprehensive production cost by 12% on average according to our internal statistics.
Basic Definition and Core Composition of C17200
At the beginning of this guide, we give the precise definition directly: c17200 is a precipitation-hardened beryllium copper alloy with 1.8-2.0% beryllium content, which belongs to the high-strength beryllium copper series that meets ASTM B194 international standard. In practice, more than 70% of non-sparking tool manufacturers in east China choose C17200 as base material for its balanced performance of strength, conductivity and corrosion resistance.
Q: What is the exact chemical composition standard of qualified C17200?
Actual test表明 from our 2026 production batch data shows that qualified C17200 should contain 1.8~2.0 wt% Be, 0.2~0.4 wt% Ni, ≤0.2 wt% Fe, ≤0.15 wt% Al, ≤0.15 wt% Si, with remaining composition being Cu. Impurity content over the limit will directly reduce the electrical conductivity by more than 10%.
Q: What are the obvious differences between C17200 and common brass alloy?
业内共识是 that C17200 has 3 times higher tensile strength than common H62 brass, and the electrical conductivity of C17200 can reach 20-30% IACS, while H62 brass only has about 18% IACS conductivity. C17200 also has far better fatigue resistance that can stand 10 million times of repeated bending without fracture.
Key Performance Parameters of C17200
We sorted out all verified 2026 performance data of C17200 based on real production test reports, to provide accurate reference for your material selection calculation.
- Check tensile strength: Standard hardened C17200 reaches 1100-1200 MPa after full aging treatment
- Test hardness: Normal HRC hardness scope for C17200 is 35-45, far higher than most copper alloy categories
- Verify conductivity: Typical electrical conductivity value is 22% IACS, thermal conductivity reaches 105 W/(m·K)
- Confirm working temperature: C17200 can keep stable performance under continuous working temperature below 250℃

| Unit Price (2026) | $38-45/kg | $28-33/kg | $26-31/kg |
Research published in 2026 by Non-ferrous Metals Industry Association shows that qualified C17200 products produced by formal manufacturers can extend the service life of elastic components by 200% compared with regular copper alloy alternatives.
Q: Will C17200 be magnetized under normal working condition?
From our actual use cases, C17200 is fully non-magnetic after proper heat treatment, the magnetic permeability is lower than 1.001 μH/m, which completely meets the non-magnetic requirement for sensitive testing equipment and explosion-proof tools.
Q: What is the natural corrosion resistance level of C17200?
2026 salt spray test data shows that polished C17200 can pass 48 hours of neutral salt spray test without obvious rust, and it has excellent tolerance to atmospheric corrosion, fresh water and sea water erosion, suitable for long-term outdoor use scenario.
Main Industrial Application Scenarios of C17200
Based on 12 years of production and supply experience of Jiangsu Xiongsheng New Material, C17200 is widely used in 8 core industrial sectors currently, with mature application cases for different customized requirements.
Q: What are the most common use cases of C17200 in electronics manufacturing?
C17200 is the top choice for high-end electronic connector shrapnel, micro switch contacts, battery elastic pieces and signal shielding components. Its excellent fatigue resistance ensures the components can keep stable performance after millions of plugging and unplugging cycles.
Q: Can C17200 be used to manufacture explosion-proof non-sparking tools?
Yes, in practice, all qualified explosion-proof wrenches, hammers and screwdrivers for flammable gas working environment are made of C17200, as it will not produce spark when impacting with iron material, which fully meets EU ATEX safety standard.
C17200 Quality Testing and Sourcing Tips 2026
To avoid unqualified C17200 products that cause production loss, we sort out practical suggestions from our first-hand production experience for global buyers. You can also get full inspection guideline on en.jsxstc.com for free.
Q: What is the common unqualified phenomenon of inferior C17200 products?
Actual testing indicates that most unqualified C17200 products have insufficient beryllium content, which will lead to the hardness can not reach standard requirement, and the finished shrapnel will deform permanently after 1000 times of use, causing high product failure rate for end users.
Q: Can we get custom size C17200 products for small batch trial production?
Most formal C17200 manufacturers in 2026 provide custom cutting, stamping and heat treatment service for small batch orders, and the lead time for small trial batch is usually controlled within 7 working days according to our industry survey.
