# 1Cr13Al4 Alloy Wire

1Cr13Al4 is a basic FeCrAl (iron-chromium-aluminum) resistance wire with about 13% chromium and 4% aluminum. It delivers the essential heat and oxidation resistance needed for industrial heating, while being easy to work with and very wallet-friendly.

It’s one of the most economical and widely used grades in the FeCrAl family, especially popular for medium-temperature electric heating applications.

## Key Features of 1Cr13Al4

1Cr13Al4 is a medium-to-low alloyed **[FeCrAl resistance wire](https://cvsicelement.com/resistance-wire/fecral/)**. With 13% Cr and 4% Al, it prioritizes ease of processing, low cost, and reliable performance at moderate temperatures.

- Lower resistivity — great for longer wire runs and easier voltage/current matching

- Fairly flat temperature coefficient — works well for steady medium-temp operation

- Less prone to thermal shock than high-aluminum FeCrAl grades

- Good ductility and flexibility

- Easy to draw, coil, and shape

- Low risk of cracking during cold forming

- Ideal for complex shapes or very thin wires

1Cr13Al4 is one of the most process-friendly FeCrAl alloys out there. It’s not built for extreme heat, but shines in stable, cost-sensitive heating applications.

## Where 1Cr13Al4 Gets Used

1Cr13Al4 **[resistance wire](https://cvsicelement.com/resistance-wire/)** is common in these areas:

- **Industrial electric heating elements** — heating wire, ribbons, or frames for medium-to-high temperature needs

- **Heating equipment manufacturing** — box furnaces, ovens, drying ovens, etc.

- **Cost-sensitive heating devices** — light industrial or commercial systems with moderate temperature requirements

- **Standard heating parts supply** — reliable source for consumable or standard components

## Usage Tips & Limits

- Recommended continuous temperature ≤ 950–1000°C

- Not meant for long-term use above its rated temperature

- Oxidation speeds up noticeably at high temps or high surface loads

**Quick tip:** Keep the operating temperature and surface load in check — that’s the key to getting the longest life out of 1Cr13Al4.

## FAQs | 1Cr13Al4 Basics

### How does 1Cr13Al4 differ from 0Cr25Al5? 

1Cr13Al4 has lower Cr and Al, so it can’t handle as much heat, but it’s a lot cheaper — perfect when you want good value.

### What’s the max temperature for 1Cr13Al4? 

In air, keep long-term use under 950°C.

### Can it run continuously? 

Yes — fine for continuous operation at medium-high temps with reasonable surface load, but not for extreme heat.

### Do you offer custom diameters and lengths? 

Yes — we can make it to your drawings or specs.

### Good for bulk orders? 

Absolutely — stable supply and low cost make it ideal for large-volume purchases.
