Select your method and find the perfect hardness tester and metallographic preparation for you.

Brinell hardness testers measure hardness by pressing a carbide metal ball into the material. The indentation is then evaluated visually. The Brinell method is particularly suitable for relatively soft and inhomogeneous materials.

Rockwell Hardness Tester

Rockwell hardness testers are particularly suitable for metallic materials and are known for their quick and easy operating characteristics. Rockwell hardness testers use a depth measurement procedure and require calibrated and suitable measuring equipment.

Vickers Hardness Tester

Vickers hardness testers are ideally suited to thin, hard materials and surfaces and provide highly accurate microhardness measurements. A diamond shaped prism is used to create an indentation in the material to be tested and the indentation is then assessed visually.

Micro Hardness Tester

Microhardness testers are mainly used for the measurement of small, thin specimens, brittle hardware testing, through the selection of a variety of accessories or upgrading a variety of structures can be widely used for a variety of metals (ferrous metals, non-ferrous metals, castings, alloy materials, etc.).

Portable Hardness Tester

Portable hardness testers are mobile devices that allow testing directly on the part. It is particularly useful for large parts that are difficult to move.

Metallographic Preparation

Metallographic preparation, products include cutting, grinding and polishing, and mounting etc.a

Metallographic consumables

Applications

Johoyd has a wealth of experience for hardness tester and metallographic preparation for a wide variety of different industries.

Aerospace

Aerospace Testing Material Characterization in the Aerospace Industry The aerospace industry represents key technologies of great economic and strategic importance. The development of autonomous and unmanned flight - Advanced Air Mobility (AAM) and Unmanned Air Systems (UAS) - is now in full swing, with major advances in flight management and control systems. In today's new space age, private companies are eagerly working on developing their own rocket launch systems worldwide in partnership with established organizations to meet the growing demand for space launch services. To lead the aviation industry to a sustainable future, the development of propulsion systems based on sustainable aviation fuel (SAF) (mid-term goal) and hydrogen (long-term goal) is accelerating. Existing fleets are being modernized and the demand for maintenance, repair and overhaul (MRO) of aircraft is increasing. We help our customers develop more efficient hardness testing. Discover our expertise, long-term experience and in-depth understanding of hardness testing applications for metallic materials, composites, ceramic materials and fasteners used in the aerospace industry. The JOHOYD hardness tester can be used to test the hardness of aircraft engine components, such as turbine blades, turbines, etc. It can timely detect internal defects and problems in materials, providing important basis for engine maintenance and repair.
Automotive

Bodywork The hybrid structures of modern load-bearing bodies are becoming more and more complex in order to meet the increasing requirements for occupant protection, lightweight construction and functionality. This is why today, in addition to common steels, more and more high/ultra-high-strength steels, aluminium and fibre-reinforced plastics are being used in the automotive industry. Engines and powertrains The goal of the entire powertrain development and production is the same, i.e. to increase the efficiency of the powertrain while at the same time reducing emissions. In order to meet these requirements, it is also important to lighten the entire vehicle as well as the powertrain. Engines are becoming smaller and lighter, but they are also becoming more complex due to additional features such as supercharging, parameter optimisation, hybridisation and the use of composite materials. Chassis As the direct transition between the vehicle body and the road, the chassis determines the performance of the vehicle in terms of power, safety, comfort and fuel consumption. In view of the requirements of safety-critical design of components, reliability checks must be used in the development of new materials as well as new manufacturing processes. JOHOYD hardness tester can be used for hardness testing of automotive components, such as engine pistons, crankshafts, cylinder blocks, brake discs, gears, fasteners, bearings, etc., to ensure the wear resistance, durability, and reliability of the parts, thereby improving the overall performance and safety of the car。
Materials

Hardness testing on metals is used to evaluate the resistance of a metal to deformation or permanent damage, specifically in terms of indentations or scratching. It involves applying a consistent force using a rounded or pointed object under controlled conditions to create a small dent on the surface of a metal. The size of the dent is then measured to determine the hardness of the material. To carry out a hardness test, a constant force must be applied to the material, using a rounded or pointed indenter to form an indentation on the surface of the material. The type of indenter used depends on the type of hardness test being performed. The indentation created on the surface is then measured to determine the material’s hardness. There are many methods of hardness testing available, each with their own standards and benefits, but selecting the right hardness test is usually determined by: The shape and size of the metal material sample The area of the sample that needs to be tested Ease of application In our mechanical department, we specialise in Rockwell, Brinell, and Vickers hardness tests. Our metallurgical department also offers micro-hardness and Knoop hardness testing. By comparing the hardness values of different materials, the performance of the materials can be evaluated, providing a basis for the development of new materials. For example, studying the hardness characteristics of new materials, comparing the hardness differences of different materials, analyzing the relationship between the microstructure of materials and hardness, etc. The JOHOYD hardness tester provides important experimental data and results for these studies.
Construction and Engineering

In construction and engineering, materials are subjected to significant stress and wear. Hardness testing helps in selecting materials that can withstand these conditions, ensuring the safety and durability of structures like bridges, buildings, and machinery.
Manufacture

The JOHOYD hardness tester is used for monitoring and quality control during the production process to ensure that the product meets quality standards and customer requirements. By regularly conducting hardness tests on products, quality issues with materials can be identified in a timely manner to prevent the occurrence of non-conforming products. The JOHOYD hardness tester can also be used for rapid screening and classification in the production process, improving production efficiency and product quality.
Laboratory

The JOHOYD hardness tester can be used for experimental operation and demonstration, comparing the hardness of different materials, studying the microstructure of materials, practical applications and case analysis, as well as experimental data processing and analysis. It can better understand the concept of hardness, testing methods and practical applications, cultivate practical skills and scientific literacy.
