# 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](https://cvsicelement.com/product/1cr13al4-wire/)**, but cheaper than **[0Cr25Al5](https://cvsicelement.com/product/0cr25al5-alloy-wire/)**.

## 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](https://cvsicelement.com/resistance-wire/fecral/)** 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.
