The 0Cr15Al5 FeCrAl strip is composed of iron, chromium, and aluminum. With 15% chromium and 5% aluminum, the alloy achieves a balance between resistivity, oxidation resistance, and cost. The aluminum ensures that, under high temperatures, a dense aluminum oxide (Al₂O₃) protective film forms on the surface. This layer prevents scaling and oxidation, even during rapid heating and cooling cycles that are typical in exhaust systems.
In addition to its oxidation resistance, the high resistivity of 0Cr15Al5 makes it suitable for electrical heating applications within the automotive sector. This combination of electrical and thermal stability makes it a versatile alloy strip for exhaust gas treatment and other high-temperature automotive parts.

Automotive exhaust systems face some of the harshest operating environments. Components are exposed to constant fluctuations in temperature, corrosive gases, and mechanical vibrations. The 0Cr15Al5 FeCrAl strip addresses these challenges with its ability to maintain structural integrity and resist oxidation.
It is commonly used in:
Catalytic converter substrates, where stable heating supports emissions reduction.
Exhaust gas sensors, ensuring accurate monitoring even under thermal stress.
Diesel particulate filters, where regeneration cycles demand high-temperature stability.
Heating elements in after-treatment systems, supporting efficient emission control.
By integrating 0Cr15Al5 FeCrAl strips, automotive manufacturers can achieve longer service life, improved fuel efficiency, and compliance with increasingly strict environmental regulations.
Industry Trends
The automotive industry is rapidly evolving toward electrification and stricter emission standards. Even as electric vehicles gain popularity, internal combustion engines continue to dominate in many regions, making exhaust system optimization essential. Advanced materials like 0Cr15Al5 are key to meeting stricter regulations while maintaining performance.
There is also a clear trend toward lightweight and long-lasting materials that reduce maintenance needs. By using FeCrAl strips, manufacturers minimize downtime and replacement costs, while supporting sustainable production goals. Additionally, as hybrid vehicles combine electric and combustion systems, materials with dual advantages in resistivity and heat resistance—like 0Cr15Al5—are becoming increasingly important.

When compared to nickel-chromium alloys, 0Cr15Al5 FeCrAl demonstrates better oxidation resistance at high temperatures and longer durability under thermal cycling. While nickel-chromium alloys may offer higher ductility, FeCrAl strips are superior in exhaust applications that prioritize oxidation resistance and service life. Compared to higher-grade FeCrAl alloys like 0Cr25Al5, 0Cr15Al5 offers a more cost-effective solution for applications that do not require the highest temperature resistance, making it well-suited for automotive use.
