Identification of Metals: File and Spark Tests

The file test and spark test are practical methods used to identify different types of metals in the workshop. The file test involves rubbing a metal sample with a file to observe how it behaves. Soft metals like aluminium and copper produce fine, continuous filings and feel smooth under the file, while hard metals like steel create shorter, coarser particles. The spark test is performed by holding a metal against a rotating grinding wheel. Different metals produce distinctive spark patterns: mild steel produces long, bright yellow sparks with many branches, while cast iron gives short, red sparks that end abruptly. Think of it like this: if you're working at a metalwork shop in Lagos and need to identify whether a metal rod is mild steel or cast iron, these two simple tests give you quick, reliable answers without expensive equipment. These identification methods are essential because using the wrong metal for a job can lead to structural failure or poor quality products.

💡 Exam tip: Practice both tests practically if possible, and memorize the characteristic spark patterns and filing behaviors for at least three common metals.
