Description

Chemetall’s Ardrox 8032 is a ready to use high sensitivity Black Magnetic Ink used in the Magnetic Particle Inspection process. It is available in both aerosols and bulk. The ink has a fine particle size, mineral oil and suspending agent in a high flash. It is used in conjunction with suitable magnetising equipment to locate fine surface and slightly subsurface discontinuities in ferrous materials. Typical defects found include shrink cracks, welding defects, grinding cracks, quenching cracks and fatigue cracks. Ardrox 8032 gives clear black indications when viewed in daylight.

Ardrox 8032 is a highly sensitive oil-based product for nonfluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts. It has a high flash point with good particle mobility, it uses the highest grade of particles, selected for their response to very low magnetic field strengths and also low coercivity.

Benefits

Maximise indication detection

  • Heavy buildup of highly magnetic particles around all leakage fields make for heavy-contrast indications, especially when used with Ardrox 8901 or Ardrox 8903 (White Contrast Paint)

Convenient to use

  • Inspect in all conditions without the need for darkness or UV lights
  • The visible particles come in a convenient, aerosol format to be easily carried and used in the field

Wide application versatility

  • Inspect a wide range of components without fear of corrosion or specification non-conformance

Features

  • Clear indications under visible light
  • Heavy particle buildup
  • Great particle mobility
  • Protects parts and equipment against corrosion
  • Broad spray pattern provides even surface coverage over large areas
  • Fine particle size

Specification compliance

  • AMS 2641
  • ISO 9934-2
  • AMS 3043
  • AMS 2641

Applications

Ideal for:

  • Mild and low alloy Steels

Defect examples:

  • Grinding or heat treatment cracks
  • Forging bursts
  • Laps
  • Porosity
  • Inclusions

Instructions for use

Use Ardrox 8032 with appropriate magnetisation procedure and equipment. For best results, all components, parts, or areas to be tested should be clean and dry prior to testing to provide an optimal test surface and reduce particle suspension contamination.

  1. Use in a well ventilated area
  2. For best results, apply the white contrast paint (the manufacturer recommendation is either Ardrox 8901 or Ardrox 8903) before the Ardrox 8032 to improve contrast and inspection sensitivity
  3. Shake aerosol can well before use and occasionally during application to ensure suspension uniformity and concentration
  4. Hold the can 20 to 30cm from the area to be tested
  5. Using the continuous or residual application method, spray particle suspension over the test area until it is completely covered
  6. Inspect under visible light

To verify particle concentration, perform a sensitivity check using a known test standard prior to inspection
