FeCrAl Heating Resistance Wire Features

 FeCrAl alloy has a high melting point, typically above 1400°C, and can maintain stable performance at 1200°C for extended periods.
 At high temperatures, the aluminum in the alloy forms a dense aluminum oxide (Al₂O₃) protective film, which prevents further oxidation and enhances durability.
 The material exhibits low volatility and strong sulfur resistance, ensuring long-term stability while reducing material loss and replacement frequency.
 It has high resistivity with minimal resistance variation at elevated temperatures, making it highly suitable for heating applications.
 Compared to Nickel-Chromium alloys, FeCrAl alloy offers similar or superior performance at a lower cost, providing a more cost-effective solution for industrial heating applications.

How Does DLX ALLOY Control The Quality?

  

 

1.Raw Material Purchase Control

 
Establish long-term co-operation with reputable raw material suppliers to ensure the quality stability of raw materials.
Each batch of raw materials are required to provide quality documents (such as raw material reports, composition test reports, etc.).
Through professional incoming material testing, including chemical equipment composition analysis and mechanical performance testing, to ensure compliance with technical requirements.
 

  

 

2. Production process control

 
On-line inspection of key production nodes, such as dimensional measurement, strength test, etc., to ensure that the products at each stage are qualified.
Real-time monitoring of heat treatment, welding and other processes to ensure that the process parameters meet the design requirements.
 
 
 
 

  

 

3. Finished product quality testing

 
Chemical composition analysis: confirm the product composition by spectral analyser.
Mechanical performance test: including axial, impact, elasticity and other tests.
Non-destructive testing: Ensure that the products are free of cracks, air holes and other defects through scanning, ray testing, magnetic particle or penetration testing.
Appearance testing: check whether the product surface is smooth and free of scratches, rust or other surface defects.
