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.

Frequently Asked Questions

NiCr Alloy FAQ

  • Q What is a NiCr Alloy?

    A Nickel-Chromium (NiCr) alloy is a metallic material primarily composed of nickel (Ni, 60-80%) and chromium (Cr, 15-30%), often with small additions of iron (Fe), aluminum (Al), or other elements to enhance specific properties.

  • Q What are the key properties of NiCr alloys?

    High electrical resistivity – Ideal for resistive heating elements.
    Excellent oxidation resistance – Forms a protective Cr₂O₃ layer at high temperatures.
    Good mechanical strength – Retains stability under thermal stress.
    Corrosion resistance – Resists acids, alkalis, and sulfides.

  • Q What are common NiCr alloy grades?

    Ni80Cr20 (e.g., Nichrome 80) – Classic resistive alloy (melting point ~1400°C).
    Ni60Cr15 – Lower-cost variant for moderate temperatures.
    Inconel series (e.g., Inconel 600) – High-performance NiCr-based superalloys.

  • Q What are the main applications of NiCr alloys?

    Heating elements – Furnaces, toasters, hair dryers.
    Resistive components – Precision resistors, shunts.
    Aerospace – Turbine blades, combustion chambers.
    Electronics – Thin-film resistors, thermocouples.

  • Q Why is NiCr alloy suitable for heating elements?

    Its high resistivity efficiently converts electricity to heat, while its oxidation resistance allows sustained use at high temperatures (up to 1200°C).

  • Q How corrosion-resistant are NiCr alloys?

    Chromium forms a passive oxide layer, providing strong resistance in oxidizing environments (e.g., air, nitric acid) but may corrode in reducing acids (e.g., hydrochloric acid).

  • Q What are the machining considerations for NiCr alloys?

    Work hardening – Intermediate annealing (800-1000°C) may be needed.
    Welding – Use TIG (Argon shielding) to avoid contamination.
    Avoid sulfur – Causes embrittlement at high temperatures.

  • Q How does NiCr compare to FeCrAl (e.g., Kanthal)?

    Cost: FeCrAl is cheaper.
    Temperature: FeCrAl withstands higher temps (~1400°C) but has lower strength.
    Oxidation stability: NiCr performs better under cyclic heating.

  • Q What are the limitations of NiCr alloys?

    High cost – Nickel prices can be volatile.
    Overqualified for low temps – Cheaper alternatives exist below 500°C.
    Machinability – Hardness increases tool wear.

  • Q How to select a NiCr alloy grade?

    High-temp (>1000°C): Ni80Cr20.
    Cost-sensitive: Ni60Cr15 or Fe-modified grades.
    Corrosion resistance: Mo/Ti-enhanced alloys (e.g., Inconel 625).
