The Fabrication and use of materials depends in large measure on such mechanical properties as strength, hardness, ductility and toughness. Numerical data describing these properties can be obtained from standard types of tensile, compression flexure, hardness, impact, creep, and fatigue tests.
ASMAC is able to carry out customized product testing on varied components like bearing and various types of materials like ferrous & non-ferrous metals, plastics, composites, rubber, high-temperature alloys. These tests performed vary from samples to samples and according to the needs from our clients.

Tensile :
Tensile Test measures the resistance of a material to a static or slowly applied force. The test sample will tailor to a dimension according to the choice standard (ASTM standard or customized specification). The specimen is placed in the testing machine and a force is applied. An extensometer is used to measure the amount that the specimen stretches between gage marks when force is applied.
By converting the result to stress and strain relationship, we are able to tell the modulus of elasticity, yield strength, tensile strength and fracture strength of a material.

The hardness test measures the resistance to penetration of the surface of a material by a hard object. Depending on the material hardness and apply loading, several types of hardness tests could be used:

• Brinell Hardness test
• Rockwell Hardness test
• Vickers (for micro-hardness)
• Knoop (for micro-hardness)
