Ways to Identify Metals

Concerned about the elemental quality of your metal?

Whether it is Raw Materials, Industrial Products or Waste & Recycling. Identification of metals are important to ensure a smooth production line; some of the traditional & modern methods used, below.

Traditional Testing Method

Cost-efficient but relies heavily on personnel experience plus these methods could damage the samples.
  • Surface Appearance Test
    Analyses the shape, form, colour and the surface’s smoothness / roughness. However, test method does not guarantee nor provide sufficient information needed to classify the metal.
Visual Aspects of Metals
  • Rockwell Test
    Measure the hardness of the metal (by the depth of an indentation made by a cone-shaped point in a Rockwell hardness-testing machine). Can only measure one part of the metal.

Modern Testing Method

Can now prevent sample damage during analysis. Positive material identification (PMI) can provide accurate test results within seconds of analysis; thanks to improved processing speed on modern technology.

X-ray Fluorescence (XRF)
uses high-energy X-rays, to force excitement in the sample to emit certain characteristic rays which are readable by the XRF spectrometer to identify its element.

Optical Emission Spectrometry (OES) uses light intensity to emit a particular wavelength from a sample to determine its element. Each metal type has their own unique emission of rays and light.
Rockwell Hardness – Test Method

Traditional methods can takes years of training to master the right skills to apply its methodology. By using spectrometers, metal workers can be trained and begin their projects within minutes.
