The accurate measurements of the hardness value of any material can only be determined by a dependable hardness tester. In mechanical testing of hard materials such as metal, the Rockwell and the Brinell-Vickers are often used. The tester has to guarantee reliability, accuracy and long service life.
The Value of a Hardness Tester
Evaluating the properties of materials during production gives deeper insight into their durability, strength, capabilities and flexibility. Hardness testing is easy to perform, and most of the equipment needed is easily available. Most importantly, the test can be carried out on the product directly without the need to alter it. Previously, testing techniques involved minor scratching, while today, the advancement in technology has introduced more advanced tools.
Indentation hardness testing is the most common industry technique. It is a simple method, compared to ultrasonic, rebound and electromagnetic approaches. Here, an indenter is loaded onto the testing material to measure the dimensions or the penetration depth. Rockwell, due to its quick turnaround time, is the most leveraged technique for metals and alloys. Vickers and Knoop are common in the testing of thin materials and coatings while Brinell is mostly used to test the hardness of cast iron, aluminium and steel frameworks.
The Tests Ensure Quality
New industrial products are introduced every day. The components used in creating them are often new, and the technologies employed are also mostly technically novel. Hardness testing ensures that the products reaching the market are of a high standard and innovative.
With a hardness tester, the manufacturing process can benefit from high-quality materials. If you do not understand the properties in a material, it gets hard to make proper combinations. Ideally, it serves as a quality control process.
