If you are designing an electronic component or auditing a material supplier, having an accurate C10100 data sheet is the first step. C10100, also known as Oxygen-Free Electronic (OFE) copper, is the highest purity grade of copper available in the commercial market.
Understanding the specific C10100 copper properties-from its ultra-high electrical conductivity to its thermal stability-is essential for ensuring your project meets global engineering standards. Below is a comprehensive breakdown of the physical and mechanical data for C10100 Oxygen-Free Electronic copper.
What are the physical properties of C10100 copper?
The physical constants of C10100 are defined by its 99.99% purity. Unlike standard copper alloys, the absence of oxides and impurities makes its physical behavior extremely predictable, especially in vacuum and cryogenic environments.
C10100 Physical Properties Chart
| Property | Metric Value | Imperial Value | Search Keyword / Parameter |
| Density | 8.94 g/cm3 | 0.323 lb/in3 | C10100 density |
| Melting Point | 1083 °C | 1981 °F | C10100 melting point |
| Specific Heat | 385 J/(kg·K) | 0.092 Btu/(lb·°F) | Heat Capacity |
| Thermal Expans. | 17.0 µm/m·°C | 9.4 µin/in·°F | Coefficient of Expansion |
C10100 Mechanical Properties: Strength, Hardness, and Ductility
The mechanical performance of C10100 depends heavily on its temper (how much it has been cold-worked). Whether you are sourcing a soft-annealed C10100 Plate, Sheet or a hard-drawn rod, these values are the industry benchmarks.
C10100 Tensile Strength and Hardness by Temper
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness (Rockwell F) |
| Annealed (Soft) | 205 - 245 | 50 - 85 | 40 - 55 |
| Half-Hard | 260 - 310 | 170 - 240 | 60 - 75 |
| Hard | 315 - 380 | 275 - 340 | 80 - 90 |
If your application involves precision machining, the C10100 tensile strength ensures the material won't deform under stress. For components requiring complex shapes, we suggest referring to our guide on Machining C10100 Speeds and Feeds to optimize your production.
Electrical and Thermal Conductivity: The 101% IACS Advantage
The most famous of the C10100 copper properties is its conductivity. While standard electrical copper (C11000) hits 100% IACS, C10100 consistently reaches 101% IACS.
Electrical Conductivity: 0.586 x 10^6 /cm·Ω (at 20°C)
Thermal Conductivity: 391 W/m·K (226 Btu/ft·h·°F)
This superior C10100 thermal conductivity is why it is used in C10100 Seamless Tube & Pipe for high-end cooling systems. For a deeper dive into what these numbers mean for your energy efficiency, read our previous analysis of the science of 101% IACS.
Sourcing Certified C10100 Materials
When procurement managers search for C10100 properties, the ultimate goal is finding a material that adheres to ASTM B170 Grade 1. GNEE METAL ensures that all our C10100 Round, Square & Flat Bar and other formats are tested to confirm these physical and mechanical limits.
We provide full traceability for every batch. If you are currently comparing quotes, our guide on verifying a C10100 MTR will help you confirm that the data on your test report matches the official C10100 data sheet.
