Product Name – Copper wire, 1.0mm (0.04in) dia, Puratronic™, 99.999% (metals basis) Quantity/Pack Size – 5m, 25m, 1m Form – Solid wire Grade – Puratronic™ (99.999% metals basis) Application – Electrical conductivity, thermal testing, calibration
Product Overview
This Puratronic™ 99.999% pure copper wire is engineered for applications demanding ultra-low impurity levels and consistent performance. The 1.0mm (0.04in) diameter ensures optimal balance between flexibility and structural integrity, making it suitable for intricate lab setups where precision is critical. Unlike standard copper wires, this variant undergoes rigorous purification processes to eliminate trace contaminants, ensuring reliable electrical and thermal conductivity without signal interference or degradation. The wire’s uniform composition minimizes variability in experimental results, while its high ductility allows for easy shaping or soldering without compromising purity. Compatible with most standard lab equipment, it serves as a dependable component for calibration, circuit prototyping, or as a reference material in analytical testing. The three available lengths (1m, 5m, 25m) provide flexibility for small-scale experiments or bulk requirements, reducing the need for frequent reordering. Store in a dry, inert environment to prevent oxidation, though the Puratronic™ grade offers enhanced resistance to surface corrosion compared to lower-purity alternatives.
FAQs
1. What is the maximum current this copper wire can handle without overheating?
The current capacity depends on ambient conditions, but at 1.0mm diameter, it typically supports up to 5-7A continuously in open-air lab environments. For enclosed setups, derate by 20-30% to account for limited heat dissipation.
2. Is this wire compatible with silver solder or only lead-based alloys?
It bonds well with both silver solder (Ag-Cu alloys) and lead-free alternatives, though we recommend using flux specifically formulated for high-purity copper to prevent oxide formation during soldering. Avoid zinc-based solders as they may introduce impurities.
3. How does Puratronic™ grade differ from OFHC (Oxygen-Free High Conductivity) copper?
Puratronic™ undergoes additional refining steps to achieve 99.999% purity, reducing oxygen and metallic impurities below OFHC standards (typically 99.99%). This results in lower electrical resistance and superior performance in sensitive applications like cryogenic testing or semiconductor research.
4. Can this wire be used in vacuum chambers without outgassing?
While the wire itself has minimal outgassing due to its high purity, residual surface contaminants from handling may require pre-baking at 150-200°C for 1-2 hours in vacuum to meet UHV (ultra-high vacuum) standards. Avoid lubricants or coatings during installation.
5. What’s the shelf life if stored unopened in original packaging?
When kept in the sealed original packaging under dry conditions (RH <40%), the wire retains its specified purity for 3-5 years. Exposure to humid or corrosive environments may accelerate surface oxidation, though the bulk material remains unaffected.
