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. 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 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.
