1cr20al3 Wire

1Cr20Al3 resistance wire is a mid-temp FeCrAl (iron-chrome-aluminum) alloy with around 20% chromium (Cr) and 3% aluminum (Al). It boosts oxidation resistance and max temp while keeping costs reasonable.

It’s basically the upgraded version of 1Cr13Al4, but cheaper than 0Cr25Al5.

Key Features of 1Cr20Al3 Resistance Wire

Bumping chromium to 20% and dropping aluminum to 3% gives it a nice balance of oxidation protection and toughness.

• Way better at fighting oxidation than 1Cr13Al4—you can run it long-term at 1050°C easy.
• Oxide layer builds at just the right pace—not too thick or brittle—perfect for gear you turn on and off every day.
• Resistance stays pretty steady over time, so power output doesn’t drift—awesome for always-on stuff like drying tunnels or continuous annealing furnaces.
• A tad harder to work with than 1Cr13Al4 (higher Cr), but still no big deal.

That 20% chromium helps it build a tougher oxide layer in mid-high heat air, so it lasts longer than 1Cr13Al4 under heavier loads and longer runs.

Where 1Cr20Al3 Resistance Wire Shines

You’ll find 1Cr20Al3 FeCrAl wire in spots like:

• Industrial furnaces and heaters: Wires, meshes, frames for mid-to-high heat jobs.
• Ovens and heat treatment gear: Gives even, steady heat.
• Always-on heating systems: Solid lifespan with proper loading.
• Bulk heating components: Perfect standardized material for big orders.

Usage Tips & Limits

Stick to ≤ 1100°C for best results: Going hotter risks the oxide layer not protecting well long-term.

Not for crazy high-power setups: It’s built for long life at mid temps, not pushing extremes.

FAQs | 1Cr20Al3 Basics

How’s 1Cr20Al3 better than 1Cr13Al4?

More chromium means way stronger oxidation resistance and higher heat tolerance.

What’s a safe long-term temp?

In air, keep it under 1100°C for steady long runs.

Good for non-stop industrial gear?

Yeah—runs stable continuously if you design the load right.

Can it swap in for some 0Cr25Al5 jobs?

Totally—great cheaper option when temps stay below 1200°C.

Custom specs and bulk orders?

You bet—built for B2B custom and long-term bulk.
