Hey there, fellow makers, engineers, and industry pros! If you’ve ever found yourself staring at a spec sheet wondering whether to grab N4 pure nickel wire or N6 pure nickel wire for your next project, you’re not alone. These two grades look almost identical at first glance, yet one tiny difference in purity can make or break performance in batteries, aerospace parts, or medical devices.
At DLX Alloy, we’ve been crafting pure nickel wire for over 20 years, and we’ve helped thousands of clients pick the perfect grade. Today, I’m walking you through everything — from chemical makeup to real-world wins — so you can choose with total confidence. Let’s dive in and clear up the confusion once and for all!
Picture this: your smartphone battery, the electric car you drive, even the pacemaker keeping someone’s heart beating — they all quietly rely on pure nickel wire. It’s not flashy, but it’s incredibly reliable.
Pure nickel wire delivers outstanding electrical conductivity, corrosion resistance, and the ability to handle extreme temperatures without breaking a sweat. Whether you need thin 0.02 mm strands for delicate electronics or robust 10 mm wire for heavy industrial use, this material just works.
At DLX Alloy, we don’t just sell pure nickel wire — we engineer it to solve your exact challenges. Our customers in 50+ countries tell us the same thing: once you try DLX N4 or N6 pure nickel wire, you never go back. But before we compare the two, let’s meet the contenders properly.
Think of N6 pure nickel wire (also known as Nickel 200 equivalent) as the dependable all-rounder in your toolbox. With 99.6% nickel content plus cobalt, it’s the go-to choice when you need solid performance without paying premium prices.
At DLX Alloy, our N6 pure nickel wire comes in diameters from 0.02 mm to 10 mm, bright-annealed or hard-drawn, with tolerances as tight as ±0.005 mm. It offers excellent ductility, easy weldability, and works beautifully in reducing environments. You’ll find it powering everyday applications where temperatures stay under 315°C and budgets matter.
Now enter N4 pure nickel wire (Nickel 201 equivalent) — the high-performance superstar with 99.9% nickel purity and ultra-low carbon. If N6 is your reliable sedan, N4 is the sports car built for the racetrack.
DLX Alloy’s N4 pure nickel wire shines in high-temperature settings because that extra purity and lower carbon prevent embrittlement. Higher yield strength (≥200 MPa), a slightly higher melting point (1455°C), and superior stability make it the favorite for critical applications where failure simply isn’t an option.
Let’s get technical but keep it real. Here’s exactly how DLX Alloy’s two flagship grades stack up.
N6 gives you 99.6% Ni+Co with a bit more iron and carbon tolerance. N4 ups the ante to 99.9% — that 0.3% difference is huge when you’re dealing with extreme conditions. Lower impurities in N4 mean fewer weak spots and longer service life.
| Grade | Ni+Co | Cu | Si | Mn | C | Mg | S | P | Fe |
| N4 | 99.9 | ≤0.015 | ≤0.03 | ≤0.002 | ≤0.01 | ≤0.01 | ≤0.001 | ≤0.001 | ≤0.04 |
| N6 | 99.6 | 0.10 | 0.10 | 0.05 | 0.10 | 0.10 | 0.005 | 0.002 | 0.10 |
| Ni201 | ≥99.9 | ≤0.25 | ≤0.35 | ≤0.35 | ≤0.02 | / | ≤0.01 | / | ≤0.40 |
| Ni200 | ≥99.6 | ≤0.25 | ≤0.35 | ≤0.35 | ≤0.15 | / | ≤0.01 | / | ≤0.40 |
Both grades boast tensile strength ≥450 MPa and elongation ≥40%, but N4 pure nickel wire edges ahead with higher yield strength (≥200 MPa vs ≥150 MPa). That extra muscle means it holds shape better under stress — perfect for springs, connectors, or structural components.
N6 actually wins on thermal conductivity (90.7 W/m·K), making it fantastic for quick heat dissipation. N4, however, offers more stable expansion (13.0 µm/m·°C) and is less likely to warp when temperatures swing wildly. Electrically, both are stars, but N4’s higher purity delivers consistent performance in sensitive electronics.
In reducing media, both resist corrosion beautifully. Yet N4 pure nickel wire from DLX Alloy pulls ahead in alkaline or high-heat scenarios because lower carbon stops graphite precipitation that can weaken the material over time. Your equipment lasts longer, and maintenance costs drop.
The electric vehicle boom runs on pure nickel wire. DLX Alloy supplies N6 pure nickel wire to battery connector manufacturers who love its cost-effectiveness and conductivity. When the project demands ultra-reliable tabs that survive thousands of charge cycles at elevated temperatures, our clients switch to N4 pure nickel wire without hesitation. One major EV supplier told us their failure rate dropped 40% after switching to DLX N4!
From sputtering targets to radio components, N6 pure nickel wire keeps signals crystal clear. In vacuum electronics and specialty bulbs, DLX Alloy’s ultra-clean N4 grade prevents contamination that could ruin performance.
Need non-magnetic implants or surgical tools? N4’s purity is non-negotiable. In aerospace engine parts or chemical reactors, DLX Alloy customers choose N4 when temperatures climb and safety is paramount. The difference? Peace of mind.

Need maximum purity for medical or vacuum use? → N4 wins.
Looking for great conductivity and ductility? → Both work, but N6 often does the job perfectly.
